You are welcome--I find the best way to learn is to share what you are learning. This exercise I can`t really help much on, though...It looks pretty good ^_^

[mitchoo]

Great lessons! Here is my take. This is quiet new for me, I knew about values etc. but never looked at them this way. Got some tips?

Thanks for this image.

I just started coloring recently and i was trying to think how sphreres can be colored and the details about the lighting.

While this image is helpfull does any of you have any some begginer tutorials about acrylics or geometrical shapes.

Edit: Seeing the previous pages heres a nice exercise.

Try to create a sphere with 2 light sources.For extra point let them be different color.

elo.1st post woo. 3d artist here trying to paint shit. this thread is soooo big. i dove in and started with ex.2 on spheres.

tell me if im doing anything outrageously wrong, from what i gathered, u can get away with anything as long as the value reads correctly??? idk. i need to study colour theory more.

[anjyil]

Mitchoo-- Nice start for the exercises. I had never heard about the eyelash trick, though I had heard about blurring your vision to help. I think the big thing is that the transitions are very sharp in your word. Values should be gradual, regardless of the material. You will want to work on blending, especially on the computer. That takes time and patience.
The light value above the sphere is a great idea and really helps you align your shadows well. I wish I had some suggestions for transitioning between colors and grayscale, but unfortunately I haven`t found the quick answer. It is just practice and practice. Take the object, photograph it, then turn it into grayscale on the computer. I also heard that you can take a piece of colored glass and use that instead of using the computer.


TheGreekDollmaker-- there are a lot of tutorials about spheres and geometrical shapes. You can check deviantart.com, or even just use google. I don`t have any of my own links with me right now--sorry ^_^;


SSquir33--I think that it would have been better to have the light source more near the front of the sphere to see it easier and give more shape, but in all I think you got the right idea. There is the answer key somewhere in this thread but I am not sure where... ^_^; As for color, there are actually some extremely strict rules that if not followed can make the image look really bad--even if the composition is good. It has a lot to do with complimentary colors, contrasting colors, hot, cold, and several other things I haven`t figured out yet. I have only dabbled in color-theory, but I have seen the wrong things really hurt a piece. It is not just value, unfortunately.

Sorry I don`t have any of my links on me today...a quick google search may help on some of these. The answer key is buried, I think...

Um yeah I guess this is task1?

Tbh the shadows are much more difficult to get right, I'm confused though, if the sphere rests on a surface, is the cast shadow supposed to be a simple grey? Shouldn't it be taking on the colour from the surface beneath it? (unless its a deep deep shadow in which case its just black).

Also task 2 (EDIT)

I had a fun time with this (pardon the shabby cutouts, I was in Sketchbook Pro11 and it doesnt have a greyscale feature so I had to cut out and to PS) Still though, its really odd, I did the first purple sphere (no.1) as dark, i was close to the colour of the grey sphere but it was off by just a bit dark, so I lightened up the sphere slightly in purple no.2, still a bit dark, but better.

hey all, this thread is really cool. I was just looking for back to basics sort of excercises.

I made two attempts at exercise 2. I went too dark in the first one. My values are much more accurate in the second one but still not perfect. The value around the highlight is too dark I think. Still new to digital.. my control is kind of lacking and I still can't get the transitions smooth.

Here are my results:

[Lois Tan]

Good exercise Never really thought about lighting so much.
I think the 1st difficult for me is, should I draw the dark part 1st, or the light part 1st?
I'm still a bit confused, but I chose the dark part 1st. I find drawing layer upon layers very difficult. some how, my form shadow didnt really turn out the way I wanted it. Yet I'm kinda stuck as to what i can do about it.
Please give me ur critiques

hi i found this site really helpful when studying the effects of color light and shadow. its done by a concept art member.

http://www.huevaluechroma.com/

V, informative will explain why the highlight always needs to directly face the viewer (i.e YOURSELF! ) and why the terminator (where light goes into shadow) is always at a right angle to the light source (try it u will see!)

[Pete Hidalgo]

So I just caught wind of vol 1 of this thread and I must say I am going to have to start re evaluating my abilities and put forth much more effort.

GREYSCALE- As I was doing this one I set a pre determined color from dark to light. Layed down layers of color ranging from black to white. I used 5 shades from dark to light all with a 100% hard brush. After I decided to drop the opacity and eye drop color layering it at different opacity's getting a greydation between the colors. When I was happy with that i switched to a soft brush and repeated the last step.

Color-Since this is just practicing I attempted to create the colored version the same way I did the grey scale.

All I can say is I must study forms moar and focus a lot more on values, because my conversion f the colored version looked more dull than the grey.
Looks like I will also be redoing this to match Vol 2.0 exercise requirements.

Hey guys!

This is my first attempt of the first exercise!
I'm from Brazil and i'm struggling to understand the exercises because of my level english... ( learn by yourself its hard! )

[Lo-L0]

hi, I love your workouts and I would like to share on a French forum. Does it bother you there?
I do not intend to assign your tutorial course.
thx

Exercise Three: Compound Response

Ok, first up is the generic key I wrote up when I wrote the exercise; after that is a specific response - you might just want to switch back and forth. ö

General:
3: Pure red, since our lightsource has the 'maximum' amount of red and our object reflects the 'maximum' I think 100s and 100b (PS) is appropriate. Shadows, if you chose to include them, would be less B but same S. Highlights if there were any would technically be 100s 100b so perhaps you would leave some room in the full light for them.

hey, i hope this havnt been discussed here before, i got a question on this exercise:

"Ok, taking our perfect white lightsource"

Exercise says "perfect white lightsource", does it behaves exactly the same on a sphere only emitting perfect blue as a perfect blue lightsource? i hope you are getting my point.

imho perfect white does not behave the same way in this example, i did this exercise and considered that a perfect white lightsource must be somehow very intense and would dilute the first lit tones in saturation...just a bit. same confusion for the shadows, how can the shadows be as saturated as the halftone if we dont consider reflected light? the darkside of the sphere (roar!) isnt selfilluminating or something, i dont get it... plzzzzzz someone help me out of this confusion, and please overthink it yourself..thanks!

little sidenote: i usually test all my thoughts on this in little setups i do here in my room or on my roofgarden since i havnt got a 'perfect white lightsource' its hard to find out that way..

Edit:

after reading some stuff about it on huevaluechroma.com, i cant find something about desaturation from light :/ MY HOLE LIFE IS A LIE.
okey, to break it down as a rule, how can i describe it? Perfect Light emits perfect Saturation, so an Object with an HIGH-Satuarted Material can not be desaturated by light? but i dont get how desaturation of light works... i hate those situations -,-

Edit2:

im doing my research like crazy and maybe got the point, i hope you correct me if im wrong:

Perfect White Light-Source means, every Color in the Light-Spectrum is there, in the same Concentration. So, there can only be 100% Saturation in the reflected Light of an Object. The Saturation wont be reduced in the shadows as long there is no Second Lightsource causing a hue-shift..which impurifys the Color. This leads me to the thought that only impurity of Light causes Desaturation on Objects.

On simple Blue-Sky and Sun Setup it would be true, that we got desaturation in the shadows and in the Lightsides. Only hues that match the Hue of the Sunlight would keep most of the Saturation... so it makes sense that a Complimentary Color causes the most appropiate Desaturation possible.

What do you guys think?

HOPE ANYBODY IS STILL ALIFE

Just Discovered a Color-Theory thread, should probably ask there and not bugging you here maybe
