Does anyone have any ideas of a pricing structure for artwork? For example, how much should be charged for a full colour render, or a logo, book cover etc.?

Is it wise to charge by the hour when doing a poser render as opposed to putting an acceptable price on the finished product?

My first advise would be to get some printing prices first, see how much it will cost to print per size, and factor in shipping if any, then decide how much you want for profit.

As an example, I went to Kinko's and got a quote on an 8 x 14 full color print on watercolor canvas, {unstretched btw} and it was going to run me close to $60.00 USD

Digital output of course would be less expensive, so you would take into account how much time and attention to detail you put into the renders..and base your final price on that. Also look around at some others artwork you can find on the net, and see what base prices they are selling at for digital output, and what kind of detailing went into the renders

Check out the small prints at CafePress to see what I mean...large base price. So going thru someone like that, it will really cost you more than you will profit

Further, Im not so sure about charging per hour on a Poser render...some of those render times are horrendous..and alot of people might not like the price..I myself would go for a flat charge upon final render.

Hopefully others will be along shortly and have some good ideas for you :)
