I think it's essential to cover all aspects of exactly what each party is contributing on a tf shoot, be it either cd or prints before the day of the
shoot.No hard and fast rules as I see
it.My good lady has never expected nor implied anything should be offered except for the agreed media ie:cd/prints.
A common sense approach prevails in most cases, I wouldn't expect a model generally to travel nationally for a
TFCD shoot, would be very expensive I'd imagine both in terms of fares and travelling time.However for a more local shoot, I suspect they may be willing to cover their own travel, depending on what the shoot could bring to their portfolio.
I have heard of some models, especially new girls refering to tf shoots as "free shoots" however just because no currency changes hands, this is far from the case, time on both shoot and any editing work is valuble and cannot be classed as having no value just because no money is exchanged.
Very much a mutually beneficial arrangement if arranged properly to both parties satisfaction.
