Here are a couple of thumbnail sketches I did for my next painting. Thumbnails give me a chance to work out the composition of the painting and determine where my focal point will be.
I’m going with the bottom sketch.
This painting will be done in oil and on a canvas 24 x 30. This is bigger than I normally work. I will be attempting to paint the jewel so that it will glow. To get this effect I will use the colour theory “law of field size”. This theory uses a large dark field/background with a smaller foreground of pure colour. For my painting, the smaller foreground is the actual jewel in the top brooch. The rest of the painting will be in various shades/values of grey.
