Rendering Discussion: "Edges" Tips and Tricks
I wrote this up as part of a reply to this thread, but I thought it was worth reposting here.
Edge basics 101: There is a scale of edges, just as there is a scale of values. It goes from hard>firm>soft>lost. Just as with value, you can use the whole scale in one picture or just a piece of it. The careful manipulation of edges is one of the most overlooked, but most important, tools an artist can use to create form, atmosphere, and believability. In general, edges are: Harder in the light, softer in the shadow Harder in bright light, softer in dim light Harder in focused light, softer in diffused light Harder in the foreground, softer in the background Harder on smooth forms, softer on textured forms Harder on hard forms, softer on soft forms (Duh, but really) Harder on flat forms, softer on rounded forms Harder on thin forms, softer on thick forms Harder on still forms, softer on forms in motion (on moving forms they are harder on the leading edge and softer on the trailing edge) Harder at the center of interest, softer as you move away The above are additive. So a kitten, far away, in the dark, would be really soft. Of course, any of these guidelines can be ignored/modified for pictorial effect.

Dear Elwell,
I'm just rewriting these points and feel like I don't really understand some of the latter ones. I.e; Harder on hard forms, softer on soft forms Can you give an example of this? I'm confused. Lead would be a hard form with a softness to it's edges, but jelly (or jello) would be soft with a hard edge. Or am I getting this confused with spectoral highlights? Harder on flat forms, softer on rounded forms Like a cardboard box compared with a ball? A D20 compared with a marble? Harder on thin forms, softer on thick forms Like a thin straw compared with a thick pipe or barrel? Also (and this is going to sound stupid but...) what is the definition of an edge? Would it be safe to describe an edge as, 'A transition caused by either light hitting adjacent surfaces of a single object or adjacent overlapping objects/surfaces'? I know this was posted sometime ago so anyone want to have a go at it? Regards, EtaCarinae

In painting the figure, areas where bone is close to the surface (nose, collarbones, kneecaps, etc) are handled with harder edges than fleshier forms. Quote:

Remember, these aren't hard and fast rules! If something has to be harder or softer than it "should" be to do it's job in the picture, good! The main point is to think about and design your edges with as much care as you would put into any other aspect.

I'm new to the concept of painting in layers. I'm more used to doing something in pencil, then finishing all the edges with ink.
When you paint, how many layers do you do, and at what layer will the edges appear? Especially the hard edges. At the end? If you don't have any solid boundaries while you're working, how do you keep a sense of the shapes of things?

Your second question seems to be a bit of a misunderstanding. You can have solid boundaries from the very beginning. This tutorial is simply showing the general firmness that the edges of a particular form should have in a given light, focus, or distance. It is this hierarchy of edges that can create a true sense of visual depth in an image. |

Just one of the reasons why I love these forums. There is always some nugget of condensed knowledge lurking
I think a lot of this is stuff I've often used to various degrees, but never really stopped to think through. Having someone point it out really makes a difference in being aware and giving it a little extra thought. Thanks! |

So if edges are softer on textured forms, and harder in bright light, how would one depict holy kitty?

I know it's somewhat a facetious question, but...
What you have there is an example of halation, which occurs on strongly textured or hairy/fuzzy surfaces in rim and backlighting. Notice how the outside contours are harder in the lit than in the shadow areas. Also, photography exaggerates these effects. The lights wouldn't appear nearly as blown out in real life, and the individual hairs and whiskers wouldn't be as distinct.

Thanks, Elwell. Although the picture is inherently ridiculous, I was genuinely curious.

Mihail, thanks for those links. I especially like Kearns' emphasis that edges have to be designed rather than observed.

This symmetry is a hierarchy of edges with the design elements with a painting. The aim is to generate dominant and subordinate edges which act to reinforce the overall compositional intent-forcing a viewer's concentration on a single focal point (without being vulgar). Mozart would have tried for this if he had been a painter. Such an integration is the way we naturally see things anyway, but it is anything but easy in a painting.
