I do use photographs of birds as reference, but I prefer to paint from a specimen, which is why I seem to have a number of reference paintings of dead birds.  A commission of a painting like the partridges (12 by 18 inches) would be about £1,500 but I will often include the preliminary sketches as part of a small “commission archive”.

The paintings of specimens were done from the collection of bird-skins at Tring, many of which are of great historical significance.
