I've been asked to do a double dog portrait for my niece to give to her boyfriend's family. So I'll begin by posting the reference photo and showing the subsequent changes to the photo fo create a usable reference.
A lightened version:
An equalized version:
Then a version showing the poster edges so that general shapes can be seen:
I then toned an 11" x 14" gessoed Ampersand board using Golden Fluid Acrylics, Quin. Burnt Orange and blocking in the general position of the two dogs.
I have a small easel sitting on my desk so I can paint from the computer screen and be close to eye level. Hope you stay tuned and offer any advice you wish as painting dogs isn't something I do very often.
