This is absolutely horrific, a professional is supposed to use their skill to get the tone right.
I know! He sent me the raw images and I was supposed to pick out six (I think) for him to
airbrush to death edit - I got an email two weeks later asking why I hadn't sent any picture numbers and I honestly can't remember whether I ever did or not

I had to take a load myself in a hurry and whilst they weren't fantastic they were a million times better, and I finally had a website gallery. Lesson learned.
These photographers should be paying us really.
I think that depends on who is booking who, and therefore who is providing the service. If I was booked as a model I'd expect to paid, since I'm the one providing the service to the photographer. If I book a photographer to take a set of photos I expect to pay them because it's the other way round.
