Our business deals with industrial tablet pc solution (link in sig), we want to features people using our devices on the homepage, the great news is that we've found some very appropriate images from stock image sites, of people holding a clipboard, which is absolutely perfect for us, as we can simply place our products into the image.
This is far cheaper than paying models to hold our products and shooting them with an expenvie photographer.
I'm thinking is it even possible to photoshop is a way which is realistic and doesn't look tacky.
For example we acquired the image http://www.123rf.com/photo_7159198_.html
and we'd like to place our product in the professors hands instead of the ipad. Would it be possible to do it without looking tacky or "off", if the photo we have isn't exactly the same angle as in that pic.
Also how much would this job cost?
