I'm going to start looking for helpful tutorials that can be of use to photographers just getting into stock photography and generally looking to sell images for advertising purposes. The above tutorial is a good reference for color correction and sharpening of images. There are no advertising photos out there that are used totally as shot. There is always some color work you want to do before putting your images out for sale. This is good example of making adjustments the right way without taking things too far. The maker of this tutorial is http://www.youtube.com/user/DigitalAssassin.
No shoots scheduled for the near future.
