So basically, an understanding of the physical rules of light should help us break down and systematize everything we see while painting. As well as that, it may also help us foster a deeper appreciation for the world around us.
MAIN IDEA:
-The way light comes in and the types of materials it hits determines what kind of things happen in a scene.
>DIRECT AND INDIRECT LIGHTING (How light comes in)
-If light comes in in direct, parallel lines such as directly from the sun, the lighting will be direct with harsher shadows and brighter highlights.
-But if light comes in from many lines, such as sunlight through cloud cover, the lighting will be indirect, creating softer shadows and softer highlights.
>The three main behaviors of light particles
-Absorption
-Reflection
-And Refraction, but we didn't really talk about that much?
>The Materials the light hits change the way these behaviors manifest.
>MATERIAL PROPERTIES
-There are a lot of different ways that the material effects light, and certain properties can combine and make multilayered effects.
>Color is probably the most obvious one. When light hits and an object it will reflect and absorb into it depending on its color. When a white light hits a black object, most of the light is absorbed, the object appears dark. When a white light hits a white object, little light is absorbed and object appears brighter. When white light hits a red object, only the red light reflects off, it appears red and usually appears less bright than a white object in the same situation. (I think)
>Surface Roughness meanwhile determines *where* reflected light goes.
>Specular Surfaces are very very smooth at a microscopic level, and if light hits it, it bounces at a perfect angle. This makes things have a mirroring effect. Example: Mirror.
>Diffuse Surfaces are very rough at a microscopic level, and when light reflects off it, it scatters all around. Diffuse surfaces make dull, unreflective surfaces. For example: Bread. You will not see your reflection in bread, the surface is too rough, instead all the light which isn't absorbed is scattered all around.
>Surface Texture
-We didn't really talk about this much, but I think that the bumpy shiny ball Jeremy showed seems more like an example of texture at first than it is of surface roughness???
>Additional Properties
-Some objects have additional material properties besides color and roughness.
>Glazing, for example, is a thin layer of smooth, specular material over a usually rougher material. This certain je ne sais quoi that Jeremy will probably force use to paint at some point in this week. This is a multilayered material property.
>EFFECTS OF LIGHTING AND MATERIALS
>Diffuse Bounce light
-Often seen in enclosed spaces with a single direct light source. When a direct light comes into a space, it often hits a diffuse surface and suffuses through the room, creating diffuse lighting. You can see this if you turn off all the lights in a room while the sun shines through a window. All the light in the room is bounce light from the sun.
>Colored bounce light
-When a direct light hits a colored object, the color often ends up reflecting off other nearby objects. The video had a lot of great examples. (Colored bounce light often happens despite the underlying colors of nearby objects being different. Apparently if you blast enough colored light an object, the base color becomes overridden kind of. As Jeremy said, everything has reflections.)
>Speculars and Highlights
-Often in directly lit scenes, there are stronger highlights. If you have shiny objects, those objects often have very shiny, distinct highlights which are sometimes themselves called speculars, such as the little white bubbles that are always in cartoon character's eyes.
-On the other hand, in diffuse lit scenes, the highlights and speculars are not as pronounced.
>Reflections of the Scene in Objects
-If an object has a particularly specular (microscopically smooth/flat) surface, the scene around it will be reflected (including the light source which is how specular highlight occur). If the object is relatively colorless, the scene is often reflected in the same colors it appears to an observer. However, if the object is colored, the reflected scene will likely be tinged by these colors.
I think that's most of the stuff we went over? I mostly wrote this because I like taking notes/summarizing to remember things :)

Here’s my submission for Imagination Bonus Week 2. It was a lot of fun,I can definitely see this as something I’d do to spark inspiration.

amazing boost in confidence until critique, right now feeling amazing. This went so well i might do this in acrylic, graphite and markers. Thanks yo. BUT I am short of time due to exams so i might not complete those ones in time. BUT I will try my best to do those asap!!!
It looks really great, super excited to see those other versions if you get the time. Totally understand with exams though -_-

Hi every one, Im not sure where to post this but Ive struggled to create and enjoy the process of drawing due to perfectionism. I wanted to do character design to have put it off for years waiting until I was Good enough. Unfortunately by waiting so long to do what I actually wanted to do all along I've become better at doing studies, and drawing from observation than character design and story telling, and this gap has made me feel like an imposter. don't get me wrong studying is important and so is drawing from observation, but I almost never drew What I actually wanted to, and when I did I would criticize it harshly and tell my self to go back to studying, thinking my fundamentals were the problem. It burned me out and now Im 6 yrs in and my character designs still aren't very good. Now Im just trying to enjoy creating characters, illustrations and having fun. I think this year I've had the most growth out of all the years combined due to being willing to make mistakes and letting perfection go. If you're starting out please try not to get too caught up in the way your art looks, it will save you years. ( yes,I know Stan is always says this, Thanks Stan for awesome advice!)
Hey! Thanks for sharing this—it’s such a relatable story. Perfectionism can be such a tough barrier, and waiting until we feel “good enough” often just holds us back from creating what we actually care about. I went through a similar struggle before I finally allowed myself to dive into what I really wanted to make, and it was so freeing. The best advice I can give is exactly what you’re saying: if there’s something you want to create, just start now. Thanks for sharing your journey and for the great advice, and i wish you all the best on your art journey!
