TFP - Time For Print(s)

TFCD - Time For CD

TFP/CD

and I am sure there are other options.. TFDVD, TFLCD, TFEIEIO...  but since you are essentially traiding time for pictures, why not...

TFI - Time For Images

Keep it simple.  Whether it is print of CD can be discussed individually when contact is made.    Just a thought, my scientific mind wanting to keep things simple. :-)

I've seen lots of people say TFI.

You forgot TFF=time for food lol

You forgot TFF=time for food lolmaybe shhots for food

You forgot TFF=time for food lol maybe shoots for food

lol That would make it sound like you're a homeless photographer.   Stand on the side of the road "Will Shoot Pictures For Food"   

I like it, much more simple, the details can just be ironed out by the model and photog.

TFAD - Time for a drink...   

TFN - Time For Nap... after a long long photo shoot hehe
