Nice! Just a few things to keep in mind: - The core shadow will typically be more along the same lines as the terminator. - The dark halftones will be a smaller area, the area of shadow before other factors (ie reflected light) take effect. - Reflected light affects any area near another surface receiving light, so this will also affect the left cheek, jaw, and eye/note bumps to varying degrees (depending on the strength of light coming from the nearby surface). - The highlight in this scenario will be more limited, still in the same areas you correctly marked, just smaller. The surface texture of the monkey appears matte, so that will limit the amount of reflectivity to create a highlight. - Ambient occlusion will also affect any crevice with a pocket of shadow, not just between the object and ground. You can find some areas around the eye surface crevices, and the nose/ear/mouth bumps. These may be smaller corrections, but understanding the components of light both separately and how they work together early on can really help in the long run once you enter more complex subjects, as even the most masterful and complicated scenes build on top of these principles. Happy drawing and I hope this helps!

my modfac hunting assingments. distinguishing between center light and halftones is pretty hard for me. any feedbacks will be appreciated

My attempt of drawing the modelling factors with the example white ball. I found it quite hard to make the ball appear white while also differentiating the shadow mid-tones and the darkest cast shadow. Critique welcome!

Identifying modeling factors definitely gets hard with complex volumes but managed to survive this.

I have now seen the instructions and made my best of it. Took a peek at the final correct monkey-shart. Questions: I wonder what kind of dark shading is it in the eyes, under the eyelid? Is the penumpra always only located to the cast shadow on the surface/like utside the figure?

Here is my first take on this exercise. After looking at the solution and reading some comments I realize I totally forgot about the cast shadow on the face itself, which made me realize I am a bit confused about the difference between the terminator and the penumbra. If the terminator marks the frontier between light and shadow, shouldn't it also exist around the cast shadows on the face itself ?

I think I was the most confused about the cast shadow on the form itself as well as the highlights but I'm sure I've made many more mistakes. Some critique would be very much cherished, thank you.

I did the exercise in photoshop with a mouse, not a stylus. I found the lesson more challenging than I thought it would be, due to the complex shape of the monkey’s head and so I spent a lot of time with it. I made several changes as I went through it. In particular, I kept changing the shadow under the monkey’s brow, —from form shadow initially, to cast shadow, but settled on dark halftone; the reason being it was in the light family. Another thought was whether to include the ear on the right as a form shadow or cast shadow, or both.  I also had some thinking to do about the center light.  Because of the modeled surface there were some parts that seemed to be receiving center light, like the monkey’s eye on the right, even though it was surrounded by half-tone. And I wasn’t sure how broad to define the ambient occlusion. So I would really appreciate some feedback on this assignment.

You did very well, @Bradley Forbush 👍 A few thoughts: - The shadow on the ear on our right is a cast shadow caused by the head, so the edge of that shadow is a penumbra rather than a terminator. - I tend to expand the Ambient Occlusion to a wider surface area because in shading, AO is such a useful device for creating form inside shadow areas.

I’m excited to check the “module 2 feedback”. Video and hopefully get all the corrections because I dont’t feel confident this is correct. Would appreciate any feedback on this assignment from anyone. I can tell this is a weakness for me at the moment, can’t wait to get a hang of identifying these factors well!

@Dorian Iten This already makes more sense, and after some thought and doing it again I feel much more confident with my 2nd attempt and the reasons why I chose to label things the way I did. But I still have some questions . I think I’m gathering that this is a bit of a balance of using what you see (or think you see) and using your brain and thinking, “well if this surface may appear similar value, but knowing there is 1 light source and the angle of it compared to this other plane, they both can’t be center light.” Based on your assignment reviews there doesn’t seem to be 1 absolute correct view but that there is room for artist interpretation. I understand that in creating we group things together on purpose and make design choices, I am just curious if it is more exact than that or not. For instance, is the “solution mod factor” file you posted the closest to true or is there slight argument for some of the subtleties? I apologize for the wordiness and Thank you. I feel like I am finding weaknesses in my drawing already!
