If I accept a TF* shoot, I do NOT send a CD of all images. I post the images online, ask that you select your top 5 (more if it is a long shoot) and I work on those only. This ensures you get 5 quality pics rather than lots of very similar shots.
If we agree a part paid shoot, I expect this to be agreed before the shoot, what the rate is and how many images you expect. I may refuse a part-paid shoot because I may be looking for images with sole use.
If we agree a paid shoot, the rate is fixed beforehand and no images will be exchanged.
