Nice shots. I've been interested in trying this approach. Can you outline the basic process for doing this? Thks
What tools do you use? I used Photoshop, which has Adobe RAW built in. My examples will reference these tools, although similar techniques can be used with other programs with similar functionality.
First, you can play around with the saturation levels of different colors to emphasize/deemphasize them. For example, a lady bug in the grass -- desaturate the green (grass), and boost the saturation of orange/red (lady bug) and the bug will pop out in the shot.
Another technique is to "paint" pictures. I posted a couple shots where I did this. the steps are as follows: create a layer over your background shot, select the brush tool, pick a color, paint on it, and set the opacity. For example, to create "pink" cheeks, I painted red splotches where her cheeks are, set the opacity low (e.g., 10%), and it appears like a soft addition of pinkish color. I probably feathered the edges to create a soft blend.
