Here's that same tree again. I will try to post some kittens too, just to enliven things, but this tree has the qualities I need for this series and it is patient. I wrote for a few days on sky holes and now I want to move on to the parts of the foliage which are in the light. They are clearly defined in the picture above. Do you remember our illuminated sphere from long ago in the blog? Here is a link to that, if you have not seen it, here it is.
Some one asked in the posts about the tree as ball lesson, I guess we are getting as close to that now as we will.
This is important,
EVERY BIT OF THE TREE WHICH IS IN THE LIGHT IS BRIGHTER (HIGHER IN VALUE) THAN ANY PART OF THE TREE IN THE SHADOW.
There's another variation on the rule I explained in the bedbug line post I linked to above. If you obey that rule you will have the effect of light on the tree, if not you will have the effect of soil on the tree. Below is a picture of a tree in flat light. The lights are not clearly brighter than the shadows so, no light. I know you hate rules, perhaps we could call it a principle.
Ideally the light and darks on a tree should be two big shapes with one predominating. In other words an equal amount of light and shade will make your painting static and dull. OK, here are the nice kittens I promised.
