I started delivering watermarked preview discs. Basically enough file so it can be viewed on a computer. Seems to make it a lot easier for the girls to go through and select the files they want for the albums and files that they will want for prints. We also shoot 1200-1500 images and our keeper rate is about 85% so im often sending a disc with 1100 shots. They are all cropped and color corrected.
I catch some heat from photographers for doing this. But ive found that many times what i think is good and what a client thinks is good are very different. Some of the stuff i would have trashed has wound up in albums. We deliver all files that we take to the client. I have no need for any of them. The files that they select for albums get final processing and then they are included with the rest of the files on the final disc.
