I drew this pic on my tablet. I've been doing all my drawings on my tablet. I've colored it and I've tried adding depth and texture to it by doing my best to add shading and such. but they never turn out as realistic or detailed as I want. THe colors still seem flat. Any tips. Can any one teach me or give me a tutorial program on coloring and adding depth to digital pictures.

If you want your subject to have more shape and depth then having your light source so far forward probably isn't helping, because that tends to make things look flatter.

Moving your light off to the side at an angle should give you more interesting shadows and bring out the shape more.

I drew a little example of a similar shaped guy shaded with the light coming from the right. I didn't draw any features or anything cause I was trying to keep it quick... but hopefully you get the idea.



Shading is easy if you break your subject down into basic shapes. The 3 fundamental shapes are Square, Cylinder and Spear. Every conceivable surface is going to be either flat, curved, round or a combination of the 3. So learning to shade these 3 basic objects under different lighting conditions should enable you to shade anything.

You should also think about cast shadows, and reflected light. Reflected light in particular is very important for realistic shading an colouring.

Colouring is not just a matter of pure colour with a slightly darker colour for the shadows. Often the saturation vary under different lighting condition over the same surface. For example metals tend to have very deeply coloured shadows but greyed out midtones. Other surfaces (like skin) have deeply coloured mid tones but greyed out shadows.

An objects colour will also be tinted by the light around them. For example a man my have a yellow top on. but if he stands in a red room then his top will pick up all the red light reflected off the walls and appear orange. His blue jeans will pick up the red light and appear slightly purple... and so on.

You might also want to think about your use of lines. Real world objects don't have black lines around them so it's best to try and describe forms using only light and shadow if you want realism. Outlines are often okay, but surface lines like on your guys t-shirt and chest aren't so good. I would only use lines like that to suggest very strong shadows, but otherwise I would avoid.

Nar..can you please open some special "Teacher" thread for Smack? he rocks in this!

ok, i think this is a good start, and Smack already says some great stuff, if you don't have anyone with you who will show you some things in live (like i don't have) then tutorials are probably the best thing!

Thank you both for the tips. I will definitely put them to practice. I hope to come up with something that looks 100 times better.

I redrew him. It looks better I guess although it's still not that much better. What am I doing wrong?

This is actually a lot better. the creases on his shirt and his pants look much more realistic now... as do the shadows on his chest muscles.

I think where you might still be going wrong with the shadows is you are not emphasising the difference in tone enough. On his face there is very little difference in tone between the highlights and the shadows. Looking at the image in black and white will make this much more apparent.

You might also want to try working in black and white first to get your tone and shadows right. You can add colour later.

I think you might also be having some problems with saturation. When you see something blue your brain does this funky thing where it filters out all the subtle tints and shades and just calls it all "blue" like the blue you see in a paint box.

Of course objects in the real world don't tend to look like that. the only time you generally see a pure bright blue is if you are looking at a screen with a light behind it or a very ambient material.

Colours in the real world tend to get washed out. and look a lot more grey and faded than you might expect. The scale from pure grey to pure colour is called saturation. The more saturated a colour is the more pure it is. this is different to light and dark.



I found this photo online of a guy in a blue jacket. And I took colour sample from certain points to show you what I mean.

Point 1 is a pretty medium tone (blue right?) but when you look at it on the left you can see it's actually pretty grey and washed out.

Point 2 is a shaded area but seems to be reflecting light from somewhere else (perhaps a wall) on the scale it looks almost as close to purple as it does blue.

Point 3 is a dark shadow. Look how dark and grey it is compared to your shadows?

Point 4 is a flesh highlight. It looks a bit pinky in the photo, but on the scale you can see it's a dull pale yellow, obviously reflecting the yellow light.

Point 5: flesh shadow. As you can see it's a lot darker than the highlight. and this isn't even a very dramatic photo.

Point 6 is the brown t-shirt under yellow light. I think it actually looks more flesh coloured though when you see it on the scale.

Point 7 is the shadow on the t-shirt. It is hardly recognisable as brown at all. Perhaps more purply. The hint of blue probably comes from subtly reflecting the blue of the jacket.

Also pay attention to the ambient light source which is yellow. The colour of the yellow light is reflected on the skin on the t-shirt on areas of the jacket and the white wall behind. Using a single ambient colour in your own pictures will help to unify all the other colours and make them appear more realistic. It also helps you to dictate the mood of your image... cold, hot, dark etc...

Keep bringing out more highlights to it. Some dark shades could be worked in there too. Unless youre actually sticking to the animated cell shading style which then works as is.

Amazing teaching Smacks! You're so caring and thoughtful!! awwwww!!

My little suggestion would be to go for simple rather then complexe. Texture of clothing is something very hard to get a hold on. To merge learning how to shade with learning how to render texture is quite a big self imposed challenge.

The shading you drew suggests creases in the clothing, but your line suggests a smooth surface. So dont be afraid to go with big simple shapes at first when shading. Like what you did at the neck/shoulder area. I know Smacks said:"the creases on his shirt and his pants look much more realistic now... as do the shadows on his chest muscles." Thats very true, but I just think it might be an idea to master where your shades go and then refine it with texture.

Excellent suggestions Kate.
