1. Leveling: First, ensure that the easel is placed on a stable surface to allow for stable painting. The painting board or canvas should be parallel to the ground, so you can see a clear image from any angle.
2. Height Adjustment: Adjust the height of the easel based on your height and painting habits. Typically, you should position your eyes at a height approximately equal to the length of your arm's stretch, which can reduce neck and back strain during prolonged painting.3. Angle Adjustment: Depending on the perspective you want and the specificity of the painting subject, you may need to adjust the angle of the canvas. For example, if you want to paint a low-angle landscape, you may tilt the canvas slightly to better capture the scenery.
II. Drawing the Perfect Perspective 1. Determine the Perspective: First, determine the perspective you want - overhead, eye level, or bird's eye view? Understand the visual effect you want to express and adjust your perspective accordingly. 2. Study Light and Shadow: Different light and shadow affect the shape and contour of objects. Carefully study and utilize light and shadow to emphasize your subject and enhance three-dimensionality. 3. Observation: Observe your subject from the correct perspective, ensuring that all details are clearly visible. This includes the shape, size, color, texture, etc., of objects. 4. Practice and Revision: Don't be afraid to make mistakes. Continuously practice and revise during the painting process until you achieve the desired effect. Remember that perfect perspective is achieved through constant practice and revision. 5. Post-Processing: After completing the initial painting, take time to carefully examine the picture and make necessary adjustments and modifications to ensure that every detail meets your expectations and compositional requirements.
