Photoshop can be used by many artistic professions. I happen to enjoy what the program is capable of doing for us Photographers. It has such a wide range of tools and effects available to really get creative with your images. Its not just about thinning out your model, reducing wrinkles and pumping up the saturation in your landscapes. I like to use Photoshop to enhance my photographs by using toning to antique my images, using brushes to grunge them or add burn marks or wrinkles. I add vignetting or noise to really give that nostalgic feel to a photograph. Split toning, blending modes over adjustment layers, different opacities or textures, and creative blurring can really set your work aside from other photographers. The only downside to using Photoshop on your photographs is knowing when to stop!
Lately I've noticed a pattern in students that come to me for photography help. Understanding light and how your camera captures it is half the battle in photography. The other half involves you having some sort of talent to compose and create. But that crucial understanding of light can make or break any photograph and any photographer. Light can be mathematically, scientifically and visually complicated. Its not just about the temperature and color of the light, but it's intensity and its direction. Also reflecting light can interrupt or help your image, paying attention to what color the walls are, how light skin or dark someone's skin is, and a materials reflectivity, can effect your image. All these things are not to be over looked during lessons or during practicing lessons.
