Textures

4:24 PM, Thursday August 4th 2022

I just finished lesson 2 and I am now doing the 25 Texture Challenge, we only have to draw cast shadows, does that mean that when drawing a mountain for instance we don’t draw the dark side of the mountain but only shadows cast by rocks or other objects on the mountain?

Another way of saying it would be: Are all the shadows on an object (like a mountain) cast shadows?

That is correct. The "dark side" of the mountain is the result of form shading, where it's the orientation of the object as a whole that makes it lighter or darker. As explained here, we are not applying form shading in our drawings for this course, except for the crumpled paper you would have handled in Lesson 2, which is a special case, as explained in the homework section for that exercise as quoted below:

For the crumpled paper, you're actually not going to worry about cast shadows - instead, its purpose is to get you used to working with bold, clearly defined black shapes, rather than being timid and using hatching. Your crumpled paper study/gradient should be made up of clearly defined, distinct black shapes and white shapes. We find that despite breaking away from cast shadows, this helps students become bolder and more confident, which then yields better results for the other two textures that follow.

Cast shadows are always the result of one form blocking the light from reaching another surface. It's the specific shape of the cast shadow that establishes the relationship between the form casting it and the surface receiving it, and that's what we want to be focusing on here. You can also read more about this, and get more clarifications from this section of reminders.

Thanks that’s super helpful. Textures are hard…

Wescott Grid Ruler

Wescott Grid Ruler

Every now and then I'll get someone asking me about which ruler I use in my videos. It's this Wescott grid ruler that I picked up ages ago. While having a transparent grid is useful for figuring out spacing and perpendicularity, it ultimately not something that you can't achieve with any old ruler (or a piece of paper you've folded into a hard edge). Might require a little more attention, a little more focus, but you don't need a fancy tool for this.

But hey, if you want one, who am I to stop you?
