"In my opinion, paying someone $50 to be a tickle model is nothing short of scandalous."
Then pay your models what you think is a fair price. It's really pretty simple.
"In my humble opinion, this is nothing short of completely exploitative, especially given that you would pay $100 minimum to tickle an escort of the same quality of looks and ticklishness."
Then don't do it!
"Why are models so badly paid? £20 an hour seems to be The starting rate in the UK, and some models even do shoots for free to build a "portfolio"!!!"
You would be surprised at what some people will do in order to have the slightest chance at becoming famous, lol.
"So let me get this straight, there are men out there who get to work with very beautiful women and take pictures of them for FREE! Needless to say if you had a tickle fetish or a foot fetish you could satisfy it in this professio with a quick tickle or a shot of a barefoot in the pose."
And what about the model with a tickle fetish? Or the model who is an exhibitionist? She is getting her fetish satisfied too. Sounds like a win/win to me!
"What's worse, some women will even PAY a photographer to take pictures of them! Hundreds of pounds in some case."
Mmmmm, yes. Just like you pay a photographer to take family photos or photos of your wedding. That is how photographers make their living...by providing a service. If the model needs professional photos for their portfolio - to advance their career - then they need to pay for that or make some arrangement to compensate the photographer (letting him use the negatives for example).
"Does anyone else have any opinions on this. Surely women (and male models) deserve to be paid more - especially given that most won't work with any great frequency and regularity."
The fact that most won't work with any great regularity is what makes small model fees acceptable. It's not the model's main source of income.
And there are other benefits to be had, beyond simple cash in your pocket. Experience, quality photos that can be used to get more modeling jobs down the road, etc.
Speaking only for myself....I got so much (on a personal level) out of my video shoots that it very quickly became about the experience, rather than the money.
Bottom line: It's a free market. If a model wants to work for exposure, more power to her. If a model wants to demand several hundred dollars per shoot, more power to her. As long as the terms are negotiated up front and everyone involved agrees to it - more power to them.
Edited to add: Even at 50.00 - for say a 1 hour shoot - that is 50.00 an hour. I don't make that much in my regular job - and I have 20 years experience.
