PS20 Basic Concepts Part 1
Summary
TLDRThe video explains the key differences between Photoshop and Photopea, focusing on workspace customization, managing images, and tools like layers, panels, and the move tool. It highlights Photoshop's flexibility in undocking panels, dragging elements between images, and the use of smart objects. The video also covers resizing, cropping, and adjusting image modes, alongside tips for working with different color modes. Additionally, it touches on saving workflows, using the history panel, and various shortcuts to streamline navigation. The next lesson will dive into hands-on practice with Photopea.
Takeaways
- π₯οΈ Photoshop allows for a highly customizable workspace, where users can dock and undock panels, while Photopea lacks this flexibility.
- πΌοΈ Both Photoshop and Photopea use tabs to organize images, but only Photoshop allows images to be viewed side by side through tab undocking.
- π Dragging elements from one image to another is easier in Photoshop, where images can be placed side by side, but in Photopea, users must rely on copy-pasting or 'File > Place' methods.
- π¨ When placing an image in Photoshop, it becomes a 'smart object,' preventing direct modifications (e.g., erasing) unless it is rasterized.
- β οΈ Be cautious when rasterizing layers like text, as it converts them into pixels, making them uneditable in terms of font or size.
- ποΈ Photoshop uses different color modes, such as RGB, which must match between images if dragging across tabs. This issue is exclusive to Photoshop.
- π The history panel in both Photoshop and Photopea helps track and revert changes. However, Photoshop requires Ctrl + Alt + Z for multiple undos, while Photopea uses Ctrl + Z.
- π Navigating and zooming can be done using keyboard shortcuts in both programs (e.g., Ctrl + Plus/Minus, or Spacebar for the hand tool).
- π Photoshop allows for canvas resizing (under Image > Canvas Size) and image resizing (under Image > Image Size), with similar options in Photopea.
- πΎ In Photopea, files must be manually saved to a local drive or Google Drive, as it does not support automatic saving like other online apps.
Q & A
What is a 'workspace' in Photoshop?
-A 'workspace' in Photoshop refers to the arrangement of all the panels, including tools on the left, the properties bar on top, and tabs for images. It can be customized by moving, resizing, or rearranging these elements.
Can you customize the workspace in Photopea like in Photoshop?
-No, in Photopea, you cannot undock or rearrange panels like in Photoshop. You can hide panels, but you cannot move them around or customize them in the same way.
How can you move images between tabs in Photoshop?
-In Photoshop, you can drag an image from one tab to another using the Move Tool. Alternatively, you can use 'Select All,' 'Copy,' switch to the other tab, and 'Paste' the image.
What is the purpose of 'Place Embedded' in Photoshop?
-'Place Embedded' in Photoshop allows you to insert an image into your document as a 'smart object,' which can be edited separately and resized without losing quality.
What happens when you 'rasterize' a smart object in Photoshop?
-Rasterizing a smart object converts it into a regular layer of pixels, allowing you to edit it freely, such as erasing or applying filters. However, this process removes the ability to edit the object in its original form.
How do you undo multiple steps in Photoshop versus Photopea?
-In Photoshop, you need to use 'Ctrl + Alt + Z' to undo multiple steps. In Photopea, 'Ctrl + Z' can be used repeatedly to undo several steps.
How can you zoom in and out in both Photoshop and Photopea?
-You can zoom in by pressing 'Ctrl + Plus' and zoom out with 'Ctrl + Minus.' Additionally, pressing 'Ctrl + 0' fits the image to the screen in both Photoshop and Photopea.
What is the purpose of the 'magic eraser' tool in Photoshop?
-The magic eraser tool in Photoshop removes all pixels of a similar color in one click, making it ideal for quickly erasing solid-colored backgrounds. This feature is not available in Photopea.
How can you flip an image horizontally in Photoshop?
-To flip an image horizontally in Photoshop, go to 'Image' > 'Image Rotation' > 'Flip Canvas Horizontal.' In Photopea, it is located under 'Image' > 'Transform' > 'Flip Horizontally.'
What is the difference between resizing and cropping an image in Photoshop?
-Resizing changes the overall dimensions of the image, while cropping removes parts of the image to focus on a specific area. Resizing is done through 'Image' > 'Image Size,' and cropping is done using the Crop Tool.
Outlines
π₯οΈ Understanding Workspaces in Photoshop and Photopea
This paragraph introduces the concept of 'workspace' in Photoshop and Photopea. It explains that the workspace refers to the arrangement of panels, such as the tools panel, properties bar, color swatches, and layers. The key difference between the two programs is that Photoshop allows customization, like undocking and resizing panels, while Photopea does not. The 'reset essentials' function in Photoshop restores the workspace to its default state, whereas Photopea lacks this flexibility.
π Arranging and Moving Images Between Tabs
This section focuses on how Photoshop and Photopea handle multiple images. In Photoshop, users can undock images from tabs and arrange them side-by-side, whereas in Photopea, images must remain in tabs. The paragraph also describes how to move content between images using three methods: dragging (Photoshop-only), copying and pasting (both programs), and placing an image (both programs). Placing an image in Photoshop creates a 'smart object,' which can be edited separately but requires rasterization for further changes like erasing.
π§ Smart Objects and Rasterization
This paragraph introduces the concept of 'smart objects' in Photoshop. When placing an image, it becomes a smart object, which allows non-destructive editing. However, to make certain changes, like erasing, the object must be rasterized. The text warns that rasterizing converts items like text into pixels, limiting future edits. It emphasizes caution when rasterizing to avoid losing editable qualities of layers.
π¨ Color Modes and Image Adjustments
This section explains the importance of matching color modes (like RGB) when moving images between files in Photoshop, as incompatible color modes can prevent images from being moved. It also discusses the 'history panel' in both programs, which tracks user actions and allows for undoing multiple steps. Key differences between Photoshop and Photopea in undo functions are mentioned, along with useful navigation tips like using the space bar to pan around an image.
π Cropping, Erasing, and Working with Background Layers
Here, the paragraph covers essential image-editing tools in Photoshop, like cropping and erasing. It explains the difference between locked and unlocked background layers and how unlocking a layer allows for true erasing (producing transparency). The paragraph also introduces the concept of resizing brushes and erasers using keyboard shortcuts, as well as the 'magic eraser' tool in Photoshop, which is not available in Photopea.
π Mirroring, Adjustments, and Canvas Size
This section describes how to flip (mirror) images in both programs and introduces the 'black and white' adjustment, which lets users convert an image to grayscale and optionally tint it with another color. The paragraph also explains how to change the size of the canvas on which an image sits, either to enlarge the workspace or to resize the entire image. Photoshop and Photopea handle canvas resizing similarly.
πΎ Saving Files in Photoshop and Photopea
This paragraph explains the process of saving files in Photoshop and Photopea. In Photoshop, files can be saved directly to local or cloud storage like Google Drive. Photopea, however, requires downloading the file to the computer and saving it manually. The importance of regularly saving work is emphasized, as neither program saves automatically, unlike Google Docs.
π Final Overview and Preparation for the Next Lesson
The closing paragraph wraps up the lesson by recapping the key concepts of workspaces, panels, and basic image manipulation. It previews the next session, which will focus on creating a project using Photopea, starting with a background image and adding additional elements. Students are encouraged to have good notes for the upcoming lesson.

Highlights
Introduction to the workspace concept in Photoshop, focusing on the arrangement of panels like tools, properties, and image tabs.
Photoshop allows for workspace customization, including undocking and resizing panels, which is not available in Photopea.
The ability to reset workspace to default settings in Photoshop using 'Reset Essentials' under the Window menu.
Photopea does not allow undocking of panels, though it allows hiding and showing them.
Photoshop offers multiple image viewing arrangements, including dragging tabs for side-by-side viewing, a feature not available in Photopea.
Photoshop supports dragging and dropping elements between images directly, while Photopea relies on copy-pasting due to lack of side-by-side view.
Using 'File -> Place Embedded' in Photoshop to insert images as smart objects, allowing for more advanced editing options.
Smart objects in Photoshop prevent certain edits like erasing, requiring rasterization to convert objects into an editable form.
The importance of understanding color modes, like RGB and indexed color, for compatibility when working with different image formats.
The history panel in both Photoshop and Photopea allows users to backtrack through actions, with Photoshop supporting both 'Undo' and history navigation.
In Photoshop, 'Ctrl + Alt + Z' is used for multiple undos, while in Photopea 'Ctrl + Z' alone works for repeated undo actions.
The navigator panel in both Photoshop and Photopea facilitates zooming and navigating around an image efficiently.
Keyboard shortcuts for zooming in and out (Ctrl + Plus/Minus) and fitting images to screen (Ctrl + 0) work in both programs.
In Photoshop, unlocking the background layer is necessary for transparent erasing; otherwise, the background color remains.
The Magic Eraser tool, exclusive to Photoshop, allows for quick deletion of connected color areas, which is not available in Photopea.
Transcripts
all right let's start off with basic
concepts so we're going to look at the
window
and the workspace and i'm going to start
off by looking at this in photoshop then
we'll pop over and look and see what the
differences are in photo p
so first off we're going to use the term
workspace
workspace is the arrangement of all of
these panels that you see on the screen
so the tools that are on the left
the properties bar on the top that's
going to be in both our programs
the use of tabs for your images both
programs
and then the fact that we have all of
these little tabs over here
color swatches learn layers channels all
of those
that's the same in all of them but in
photoshop you can customize your
workspace
so for instance i can grab this layers
panel
and bring it out here somewhere oops i
grabbed a hold of the picture
so i can grab this layers panel and
bring it out here i can also make it
bigger or smaller and things like that
and those are the types of things that
you really can't do
in photo piece so there are some things
that are very specific to photoshop and
these workspaces
are one of those things so
um if i pull out all of these different
little things say i've just got
everything in kind of a crazy place
i can put them back by going to window
and workspace
because of the arrangement of panels as
the workspace and then i would click on
reset essentials now it says reset
essentials because i'm in the essentials
workspace right now and that's what we
usually work in in here
so i'm gonna hit reset essentials and it
puts everything back in its night
nice tidy little places okay so that's
what a workspace is and we only have
workspaces in photoshop
because in photo p you cannot undock all
your panels so let me open up photo p
here
i can hide these panels by clicking on
them and hiding them
but i can't pick them up and scoot them
that's just not something that you can
do in that program
okay so back in here
we can also change the way that we see
images when we have multiple images open
so
i can grab a hold of this little tab and
just yank down
and i can actually look at both of mine
i can yank this one down too
i can look at both of my pictures at the
same time
can't do that in photo p either if you
have a bunch of pictures
open you can go to window up here at the
top and arrange
and then you can tell it how you want it
arranged so i can say you know put them
side by side
or i can tell it to put them all back
that's consolidate
all to tabs and that puts them back in
those tabs
so again it's kind of up to you as to
whether or not you're going to want to
undock things or not but that's an
option in photoshop this gives you a
little bit more power
and control all right so how do we get a
picture
from one to the other so let's say that
i have this background i'm going to
undock it
and i have this frog and i'm going to
undock it i can take this frog with my
move tool
just point to the frog and click and
drag and
let go when i get over to the other one
and then the frog
is in there i can't do that in the other
program because i can't put them
side by side so that's kind of a problem
how can i do that a different way
let me show you let me put these back to
tabs
so let's say i have this one if i want
to take this one
and put it in the other one and you can
do this this in both of them is the same
you can go to select all which puts
little ants around the whole thing
edit copy which copies it
click on your other tab and edit paste
and now you have that in the other
document
and that's how you would do it in photo
p because we can't put them side by side
okay the third way that you can insert
pictures
so you can either drag them in or you
can copy paste
but remember you must select all first
or
you can what we call place it and you
can do this in both programs as well
so it's file place there's only file
place in photo p
in photoshop you do place embedded which
just basically means like make a copy of
it so
file place embedded and then i can go
get that saved picture
and place it it puts it in there and it
automatically if it's
bigger than the picture that's there
it won't let it hang off it always makes
it no taller
than your picture so if we were dragging
something in and it was huge mungus
it would stay huge fungus like it would
cover the whole thing and you wouldn't
be able to see that background anymore
so if you place it it kind of puts it in
there in a
in a different way it makes it a little
bit different to work with
now you might say well then why don't i
just always do that i'm going to hit
okay here
well because look down here on my layers
i'm going to undock these so you can see
better see that little icon
when you place a picture it's considered
what they call a smart
object which means that you can actually
edit that picture as if it was
still open on its own i can double click
it
and it's going to go in there and it
takes me to that frog picture
where i can like work on it and close it
and then it would update it
now that's not going to mean anything to
you at this point in the class but i
need you to understand that when you see
that icon
it means that you have it in there a
special way
and if you place it you're not allowed
to do things like
erase it see how i get a big no sign it
says no erasing
because you can't erase objects
okay to erase it we would have to
convert it
to a different form and that's called
rasterizing
some people call it flattening but
rasterizing is the proper term now if i
click to try to erase right now
it actually is going to tell you hey
this smart object
must be rasterized now caution caution
if i'm like
little lights going just because
something pops up on your screen
does not mean you click ok in this case
it does
because i want to erase but if you
accidentally were on the wrong layer
and you got ready to erase and you were
on a layer that has
like text on it you can't erase text
so if you rasterize your text you turn
your text
into pixels instead of text which means
you can't change the font you can't
change the size without it getting
blurry
so just because things pop up does not
mean you say okay
okay in this case i would want it to do
that and once i rasterize it see it's
not a smart
object anymore now it's as if i pasted
it in
okay so that's that another thing that
you have to worry about
only really in photoshop and only if
you're going to drag things across
is the color mode we talked in a
previous lesson
about color modes it's under the image
menu again this is a photoshop only and
this is where you can change the color
mode of your images
okay indexed color that's what your
gif images are going to come in as and
gif images don't play nicely
so if i go out here and try to grab one
of these images let's see
i think i have a gif well no i don't
have one if i had a gif image in there
and i tried to drag it over
it wouldn't let me i'd get one of those
no signs
so the thing to do about that is look up
here
see in the little tab it says rgb rgb
if they don't match you just go to image
and mode and you pick rgb
you say hey you got to match everybody
else so join the rgb club
okay and then you can drag it across now
if you're copying and pasting or if
you're
file placing you can put them in there
though
so just bear in mind that that may be
necessary depending on what you're doing
okay um the history panel each action
that you do appears in the history panel
if you can't find a panel
and this is in both programs you go to
the window menu
so i'm going to go to window in history
and here's my history panel
so it says i opened it i saved it i drug
it in there i moved something around i
pasted something i moved something
around i placed something and then i
rasterized the layer
so if i wanted to back way up to the
beginning when i drug that first one in
i can click back in my history instead
of hitting undo
a bunch of times you can also go to edit
and undo the state change
control z in photoshop is only going to
undo
one time so if you want to undo a bunch
of times you're best to use your history
now in photo p you can press ctrl z
multiple times
in photoshop you would actually do
control
alt z if you want to back up multiple
times
so control alt z is actually how we back
up
in photoshop and plain control z
in photo p so make sure you know the
difference between those two
um the navigator is another good one i
like to keep it up most of the time as
well
window and navigator and this allows me
to zoom up on the image
and back on the image without having to
go over and grabbing the magnifying
glass all the time
okay so we can zoom up now you can also
zoom up by using your keyboard so you
could say control plus
plus plus plus plus plus control minus
minus minus
you can press those or you can press
ctrl zero
and these work in both programs control
zero fits it on the screen
so if you got zoomed up real close and
it was like hanging off the screen and
you wanted it all to come back so you
can see it
control 0 is going to fit it to the
screen
okay i'm looking at my notes page to
make sure i've covered all of the basic
things when you're zoomed in really
closely
you can point to your navigator see how
you get a little hand
you can point to your navigator and use
that or you can come over and grab the
hand tool which does the same thing
but what i normally do is i press the
space bar
so watch when i'm pressing the space bar
and i'm holding it down right now like
it's still pressed
i can pick up and scoop this from inside
here
instead of having to go to this little
guy okay now that won't matter a lot
here in the beginnings of working with
photoshop but it will later on and
it just while you press the spacebar you
get the hand and when you stop pressing
the spacebar it goes back to whatever
tool you have which right now i have an
eraser
okay um some additional items we'll get
into in the next session when we're
talking about how to change the size of
things
and all that but i do want to show just
a couple of other items
so if we were changing the whole image
then there are a few things that we can
do
one of those things is we can
crop the whole image that's the crop
tool
and i'm sure you've seen the crop tool
and lots of other things you just
draw your box around what you want to
keep and it hits check mark
and it gets rid of everything else basic
cropping
you've done that on lots of things on
your phone and so forth
now on here on photoshop notice that
whenever we have an image and we open it
it's on a background layer
in photo p when we open an image it's
also on a background layer but it's not
locked well photoshop locks it so i'm
going to click on that and
unlock it if it's locked and we erase
we don't actually erase we end up with
some sort of background color
so i'm going to grab my eraser now and
now if i write see how i get
checkerboard
i wouldn't get that if my background is
locked so
if you're going to be erasing a
background you're definitely going to
want to unlock that background layer you
can tell because it actually even
renames the layer in photoshop
so i'm going to press ctrl plus plus
we're going to zoom up here and you can
see my little
frog now i have a kind of a soft brush
going on we haven't talked about
soft and hard brushes yet but eventually
we will
so to make your brushes bigger or
smaller and
erasers are called brushes in photoshop
they're just brushes that erase instead
of
paint um to make your brush bigger or
smaller to the right of the letter p
are brackets so if i push the left
bracket see my circle gets a little
if i push the right bracket my circle
gets big it's a lot
faster to use those keys than it is to
come up here at the top of your screen
and
change the sizes like there's a size
button but there's no reason to use it
there is literally a cat on my back
right
anyway um so that's one of the things
that you need to know about an eraser
the other thing is that our two programs
have different erasers so in photoshop
we have three erasers
and the first two we have on both um
photoshop has the best eraser which is
called the magic eraser
so let me show you how the magic eraser
works the magic eraser works by
basically
if you click it erases everything in
that color
that's connected so like this parts not
connected
but that's it it's like bam it's an
amazing eraser we don't have that in
photo p
so whenever i do the demo i'm actually
going to use photo piece so we'll put
together a document together
and i'll use photo p and show you how to
use the other erasers
the magic eraser pretty cool only
photoshop regular eraser works as you
would expect it would click and drag
around and things erase
but again if you're going to erase you
need to make sure that that background
layer
is indeed unlocked okay what if we
wanted to flip this the other direction
that's what we call mirroring to mirror
the whole
image you would go to image
image rotation and flip canvas
horizontal
and then it flips it the other way now
in photo p
it's pretty close to the same um there's
just one little difference in where to
go on the menu but
you'd be able to find it so it's in that
same kind of area
there are also some additional things
that you can do
up here under the image menu one of
those is adjustments
there's lots of adjustments in here i'm
only going to look at one of them
today which is the black and white
adjustment the black and white
adjustment will let you make it black
and white
or it will let you tint it
so that means i make it shades of
another color so i come in here and i
want to make it shades of blue
or red or purple or whatever i can do
that and then i can increase how much of
that color we're getting
so that's called tenting so basically
you turn it black and white and get rid
of the color
and then you tint it a color now this
has done the same in photo p
almost so let's take a look at it i'll
just do it with this image here
so i'm going to go to image and
adjustments and i'm going to go to black
and white
so there we go we got the same situation
if i click
colorize though so it's colorized
instead of tint
then i can come in here and pick a
different color so say blue
and okay and there we go so it works a
little bit different than the other one
but
it works so we can move these sliders
around to change
various parts of it so that's that one
to flip this one the other direction you
go to image
and then transform and then it's that
same thing flip
horizontally so as long as you kind of
know what menu to get to you can find it
regardless of which program that you're
in
it's not too hard to figure that part
out
okay resizing images so your image sits
on
what's called a canvas the canvas is
this invisible thing
so like if i pick up this frog and i
scoot him around now
that transparent area behind my frog is
the canvas that it sits on
so that's what that's called you can
make your canvas bigger or smaller
so if i go to image the image menu again
and canvas size
then i can make my canvas bigger so like
right now my canvas is five
and five inches and something wide if i
make it seven
inches wide and hit okay then my canvas
gets bigger on the edges
same thing with photo p we can also
enlarge the canvas
it doesn't work as nicely in photo p
unfortunately
um but if i go to image and canvas size
say i add this one's in pixels at the
moment but let's say i make it 800
pixels wide
then it expands it out now you can see
in this one
i hadn't deleted my image or my
background yet and so we have
transparent pixels out there but you get
the gist of it it's basically the same
concept
so enlarging canvas is the same
image canvas size and resizing images is
the same
it's under image image size and then
same d you just put in your
measurements for that same thing in
photoshop
image image size and then you can resize
the
image if you need it to be smaller you
should really never resize to be bigger
that's not considered a good practice
okay um i think that pretty much covers
the basics of it
in the demo of what we're going to do
together i'm going to use photop
instead of photoshop so for my students
if you are using it on a computer that's
totally cool if you want to use your
chromebook
that's also cool and just know that if
you're using your computer
you're either going to have to save your
file to your
actual computer drive or you can use the
google file stream
so all my computers in my lab should
have google file stream so if you go to
file save as
find the google drive file stream and if
you've never connected your account you
may have to do that
there should be a shortcut somewhere
just search for it
and then you can actually access your
google drive so these files here are
actually
on my google drive and then i've saved
this demo file there
and then it will sync up to my google
drive so that it's on my google drive
and then if it's on your google drive
technically you could even open your
photoshop file later
in photo p and continue to edit it
so even in photo p it does not
automatically save
like your google documents do so you are
going to have to take that extra time
to save your work and you want to save
it periodically you don't want to work
for an
hour and then save so you save as the
first time so you can give it a name
and then any additional saves you're
just going to go to file and save
and that's the way that works now in
photo
p it can be a little bit different
because it tends to download it so like
if i decided to save this document right
now
it's going to have me save it as a psd a
photoshop file
and technically it's going to have me
download that file to the computer
now again i can put that file on my
google file stream if i'm on a computer
or on your google drive if you're on
your chromebook so either way you can
still access that file
but you do have to save it it does not
save automatically so if you just close
out a photo p
and come back another day your file will
be gone
it won't be in there it doesn't hang on
to it for you
okay all right um
i think that's pretty much it all the
basic items here uh you'll learn a lot
more things as we put together a
document but i wanted you to at least
have an
overview of the panels and the way all
of these little things work
before we actually get into the project
so in the next
lesson let's hop into photop you're
going to be opening this background
image just like this
and we're going to start with the
background image and then we're going to
be
working with this frog fly image and
adding some additional things
in there so get ready
and make sure that you have good notes
