Menggambar menggunakan Grid

Summary

This tutorial demonstrates how to enlarge or reduce an image using the grid technique and scale. It explains the concept of scale as a ratio between the original and the actual size of an object. The grid method involves drawing a grid on both the original image and the target paper to ensure accurate enlargement or reduction. The tutorial provides a step-by-step guide, including materials needed, and emphasizes precision and attention to detail when copying the image square by square. The technique helps preserve proportions and capture intricate details in the final drawing.

Takeaways

• 😀 Scale is the ratio of the size of a drawing to the actual size of the object it represents.
• 😀 Example of scale: a map with a 1:10,000 ratio means 1 cm on the map equals 10,000 cm in reality.
• 😀 The grid method is a popular technique for enlarging or reducing images manually.
• 😀 Grid comes from the English word meaning 'network' and consists of evenly spaced squares.
• 😀 Grids help determine the scale ratio between the original image and the enlarged or reduced version.
• 😀 Example of grid scaling: a 15 cm × 15 cm image enlarged 5 times uses a 1 cm × 1 cm grid on the original and a 5 cm × 5 cm grid on the new image.
• 😀 The grid technique works by copying details from each square of the original grid to the corresponding square on the new grid.
• 😀 Smaller grid squares allow for more detailed reproduction of the original image.
• 😀 Required tools include drawing paper, pencil, ruler, eraser, and optionally a printout of the original image.
• 😀 Steps for using a grid: create a grid on the original image, number the lines, draw a scaled grid on new paper, copy details square by square, and add shading after transferring all details.

Q & A

What is the definition of 'scale' according to the script?

Scale is the comparison of the size of a drawing to the actual size of the object it represents. For example, a map with a scale of 1:10,000 means 1 cm on the map corresponds to 10,000 cm in reality.

What is the purpose of using a grid in drawing?

The grid method is used to enlarge or reduce a drawing manually while maintaining accurate proportions by dividing both the original and target images into a series of equal squares.

How is the size of each grid square determined when enlarging or reducing a drawing?

The size of each grid square on the target drawing is determined by the scale factor. For instance, if a drawing is enlarged 5 times, a 1 cm × 1 cm square on the original becomes 5 cm × 5 cm on the enlarged version.

What materials are needed to apply the grid method?

You need drawing paper, a pencil, a ruler, an eraser, and a printout of the original image.

What is the first step when using the grid method?

The first step is to choose the object or photo that you want to enlarge or reduce.

How should the grid be applied to the original image?

Draw horizontal and vertical lines at equal intervals across the object, forming a network of squares. The smaller the squares, the more detailed the reproduced drawing will be.

Why should each grid line be numbered?

Numbering each horizontal and vertical line helps in referencing and accurately transferring details from the original image to the target grid.

How do you transfer the image from the original to the new grid?

Copy the details from each square of the original grid to the corresponding square on the target grid, using thin sketch lines to maintain accuracy.

What should be done after all squares have been filled?

Once all squares are complete, add shading and refine details to enhance the final drawing.

What is the main advantage of using the grid method?

The grid method simplifies the process of enlarging or reducing images while preserving accurate proportions and details, making it useful for both beginners and experienced artists.

Can the grid method be used to both enlarge and reduce images?

Yes, the grid method is effective for both enlarging and reducing images by adjusting the size of the squares according to the desired scale.
