Selective TF*.
I will usually aim to produce 2-3 top quality, fully retouched images on a shoot, of benefit to both the models and my portfolio. Extra for the MUA of course. If we produce lots of looks we can discuss it.
If a model wishes to choose further images beyond this for her own needs I will be happy to retouch them to a high standard for a retouching fee of £35 per image (2-3 hours of work on average are involved to retouch the images).
