a study in form and light

first let me say that I haven't had this much fun since the seventh grade. And that I was looking for a subject that would be both enjoyable to Frank and that I could place on Adobe Stock. Studies have show than squirrels actually collect these things - Is it any wonder?

I have been reading "How To Render - the Fundamentals of Light, Shadow, and Reflectivity" by Scott Robertson and Thomas Bertling and I will use this image to practice and study some of the techniques that are in the book. Wish me luck and a fun journey for all of us.

Frank and Minnie, thank you guys very much for playing along. Frank knows that the fool (that would be me) needs a straight man!

First, I removed the NIK artistic filter that I had applied earlier.
Second, I learned how to use puppet warp, and curved the leaf around the acorns.
Third, I darkened the part of the leaf that would now be in shadow (camera right part).
Fourth, I converted the image to black and white - since the majority of this study will be in Value.

And here are the results from step 1-4.

Next I plan to average out some of the values attempting to reduce the "coarseness" of the texture. And an easy thing to do would be to darken those areas that are now behind the leaf...

Can't speak for step one, but steps2,3, and 4 are done well...

thanks Frank!

Now to attempt to reduce the texture imprint from the accorn, but to maintain the general value, I used a mixer brush and with very short strokes, mixed/smoothened/blurred the local contrast away. And of course it turned into a smudgy mess. But the spirit of it was close, so I just reduced the opacity of this new layer to 50 percent and merged down. This allowed some detail/texture to be kept, but also managed to lower it substantially.

Also, painted in some shadows where the fabric/leave would stop light.

I plan to mix/smooth and then bring back some detail again, but anyway, here it is for now:

A later challenge will be to make the upper part be more flat - and the lower part (fabric covered) more round!

not many will notice the shadow as I had to toggle a couple times before I even saw what shadow you were referring to, but it is rather straight compared to the leaf shape.....nitpik

thank you - my fix isn't that great, but at least it is no longer straight. (that shadow will require more work, doesn't look too good)..Smoothened one more level. Not sure what I want to do next, but probably get rid of the railing/board the acorns are resting on and work on making the shapes be less perfectly round.

you are ruined, it is too late..

struggling with this part. Added a splash of light to the top, but might need to attempt Warp.
