This is my first post, so hi everyone. I'll be posting from time to time on general photography, lighting, or Photoshop topics, most likely. These days I do mostly studio work (in my home), most of which is some kind of personal project. I've definitely developed a love for lighting in general and studio lighting in particular (if you have an interesting in lighting, definitely pay a visit to Strobist).
So I wanted to share a Photoshop technique I use for dodging and burning. Often I'm unhappy with the results from the dodge and burn tools, they tend to muddy things up or add grayish casts. Also, I'm usually wanting to add subtle contrast to make the image pop, so my goal is to dodge highlights and burn shadows in key places in the image. I'm assuming some level of Photoshop familiarity... if you have questions about how to do any of these specific steps, please ask.
I start by creating two new layers above the image. Fill the top layer with white, and change its name to Burn. Fill the second layer with black and name it Dodge. Set the blend mode of the top (Burn) layer to Color Burn, and the blend mode of the second (Dodge) layer to Color Dodge. Because the Burn layer is white, it has no effect. You'll lightly paint in black on the layer in areas you want to burn in. Similarly, the Dodge layer is black and thus has no effect. Lightly painting in white will dodge those areas painted over.
That's the basic setup... grab the brush tool, set the opacity to 5-10%, and the color to black. Select the Burn layer, then find shadows (or darker midtones) in your image that you want to enhance, and paint over them, a little at a time. Then switch your foreground color to white and repeat a similar process for the Dodge layer, painting over mid-to-highlight areas you want to brighten up.
A shortcut for getting your foreground and background colors set to black and white, respectively, is just to hit the D key. That resets the swatches. The X key is also really handy, it swaps the foreground and background colors.
Questions/comments/feedback definitely encouraged. Do others out there have Photoshop tips to share?
