Here's how I used this photo to create a painting.
I came across this old farmhouse high up in the hills inland from Benidorm in Spain, and immediately knew that i wanted to paint it. But access and parking were difficult, so I only had time to quickly stop the car, reverse back and snap a photo or two.
Back home I did a quick pen sketch in my sketchbook so that I could play around with the composition and decide what needed to be included and what didn't, and to think about the tonal structure of the picture (where to put the darks and lights). I added a dark shadow right across the front as I wanted to concentrate the viewers' eye to the house and this is a neat way of doing this.
When I was pleased with this I was ready to paint.
I used water mixable oils on a small 6" x 6" board which had been coated with gesso and then painted with orange acrylic paint.
I just used ultramarine blue, alizarin crimson and cadmium yellow, plus white.
As I painted I referred to the photo less and less - really only using it for the detail of the farmhouse. I used my sketch for the rest. In this way I was free to paint with any colours I thought would work and to let my imagination run wild, especially with the foreground. I left large areas of the orange undercoat showing through.
Towards the end I wasn't looking at either my sketch or the photo at all, just seeing what needed to be done to make the painting work. I hope it did!
