Menggambar Konstruksi Perspektif dengan Pencahayaan - Seni Rupa Kelas 9 Fase D

Summary

This educational video, presented by Miss Estter, explores the art of perspective drawing for 9th-grade students based on the Merdeka curriculum. The lesson covers creating drawings with one or two vanishing points, emphasizing the concepts of shadows and shading. It explains how light interacts with objects, creating shadows and highlights, and discusses various lighting sources like sunlight and lamps. The video also guides students through practical exercises for drawing constructions with lighting, including side, back, top, and front lighting, and highlights how these affect the appearance of shadows.

Takeaways

• 🎨 The lesson focuses on drawing constructions and perspectives with shading for 9th grade, based on the Merdeka Curriculum.
• 📏 The objective is to learn how to draw using one or two vanishing points while applying concepts of shading and shadows.
• 🌞 Light sources, such as sunlight and lamps, are key in creating shadows and shading on objects.
• 💡 Shadows form on the parts of objects not directly exposed to light, while the illuminated areas reflect light.
• 📝 Steps to drawing perspective with light include determining a light source, drawing lines from the object's corners, and shading based on intersecting points.
• 🔍 Different types of lighting (side, back, top, front, diffused) create different shadow effects, impacting how objects appear.
• ☀️ Side or low lighting, common at sunrise or sunset, creates long shadows by illuminating objects from one side.
• 🌑 Backlighting creates silhouettes, and shifting the object's position can change the lighting angle.
• 🕛 Top lighting, occurring around noon, results in smaller shadows directly below the object.
• ☁️ Diffused light, such as during cloudy weather, softens shadows and reduces contrast, creating a more balanced appearance.

Q & A

What is the main objective of the lesson in the video?

The main objective of the lesson is to teach students how to draw perspective constructions with one or two vanishing points while applying the concepts of shading and shadows.

What is the source of the main light on Earth?

The main source of light on Earth is the sun.

Besides the sun, what other light sources are mentioned in the video?

Other light sources mentioned in the video include indoor lights such as lamps, desk lamps, and other artificial lights.

What is the difference between a shadow and shading?

A shadow is the dark area formed where light is blocked by an object, while shading refers to the darker areas of an object that are not directly exposed to light.

How is a shadow formed according to the video?

A shadow is formed when light hits an object, and the side that is not directly exposed to the light remains in darkness, creating the shadow.

What are the three steps mentioned for drawing perspective constructions with lighting?

The three steps for drawing perspective constructions with lighting are: 1) Identify the light source, assuming it comes from a 45-degree angle, 2) Draw lines from the object's edges based on the light's direction, and 3) Mark the intersections of the shadow lines and shade the area to create a shadow effect.

What materials are needed for the drawing activity?

The materials needed for the drawing activity include drawing paper, pencils, an eraser, and a ruler.

What is side lighting and when does it occur naturally?

Side lighting occurs when light hits an object from one side only. It happens naturally at dawn or sunset, creating long shadows.

How does backlighting affect the appearance of an object?

Backlighting places the light source directly behind the object, often creating a silhouette effect where the object's details are obscured and appear as a dark shape.

What happens to shadows when the light source is positioned directly above an object?

When the light source is directly above an object, such as during midday, the shadows become smaller and are positioned directly underneath the object.
