Recently I came across a number of new 'models' who had done TFCDs with photographers. My disappointment to many a photo which they have shown me. The photos are very nice in the view of a photographer to extend of some even can try for contest. But what of that as a model 'selling' your services to them for free?
What you may get is a bunch of low resolution watermarked artistic junk...
The photographer's aim of the shoot is to grab hold of some pics which they are able to show off to and not to concentrate and show off the best of a model. To top it off, they are of such low resolution that you cant use it as comcards or representation materials as they are also watermarked.
So whats the best bet? Go pay for a creditable professional (hopefully as a pageant photographer in the past or a fashion photographer). Just remember that every hour you spent doing your TFCD can also be converted into cold hard cash instead of wasting your time.
