If you take a photo using Camera Raw the image on the computer does NOT look like it does on the back of your camera. I teach you how to make small changes to make it look much better than it does on the back of your camera.
I teach you how to make changes that enhance your photo so that they look their best on screen or as a matt or gloss print, and nobody will be able to tell that you carried out small post processing changes.
I teach you how to follow my workflow which means that I spend an average of 90 seconds on preparing the photo for printing or for screen. My view is that if you can tell that Photoshop work has been done on the photo, then you have not done the job properly.
