There are many nuances to the model release as mentioned above. Remember, the release is the model granting YOU permission to display her likeness under the conditions outlined in the release. Don't confuse that with copyright and usage/ license. In all likelihood if you're just doing a fun shoot, you're probably fine. BUT, say you butcher the images and the model asks you not to post them on Facebook? What if they are so embarrassing she threatens legal action? What kind of hard copy proof do you have? Additionally, your verbiage on your website is making you sound like you are pursuing more than hobby photography. If you have aspirations of one day being a paid professional, it's never too early to start conducting yourself like one.
I disagree on the first point. People are fickle. They change their mind, and they get weird for all sorts of reasons that make sense to nobody but themselves. Anything from a new ultra conservative rich boyfriend who makes it his mission to rescue a girl from her past and will stop at nothing to punish anyone and everyone who ever knew her... to... well make up your own stories. If you're going to do the shoot, take 5 minutes to execute a release. It's too simple not to.
For TFP, mine is simple: I can use all images for self promotion, and can and will publish them for self promotion but not for profit, with the following exclusions: _____________________ (Sometimes when doing "implied" nudity, the model is nude, but doesn't want nudes published. Fair enough, and I'll hand write it into the release.) I also include a "compensation" fill in clause which I write in "materials for self promotion only" to indicate that the model has been compensated with a copy of the work which can be used for their self promotion, but not sold for profit, or used for other commercial purposes.
For commercial work, should you ever choose to work for hire, ask the CLIENT to give you one to use. They are paying for the shoot, they get to make the rules. And often
nobody is allowed to use the images for
anything except for them. If they don't care, then use your TFP release, and just write the amount in the fill-in space.
On the second point I agree completely. Act like a professional.
Third point... anyone who won't sign my release (after reading it) is a HUGE warning klaxon... WARNING WARNING WARNING THIS ONE IS FLAKY WILL BE TROUBLE AVOID AT ALL COSTS WARNING WARNING WARNING.
