Back in the old (pre-digital) days, I would switch from taking photographs to etching plates every so often just to keep myself in balance. Photography is a scattershot process - you take a lot of photos, but very few of them end up being great. Printing etched plates is a nerve-wracking craft - you spend weeks on a plate trying to make it perfect - at every dip in the acid wondering if you're improving your print or about to ruin it.
These days, I mostly switch between the program "ArtMatic":http://www.uisoftware.com/artmatic/indexAMinfo.php and creating huge layered Photoshop files as epitomized in the “Atlas Of Dreams” series. The layered Photoshop files have become my modern equivalent of etching a plate, with the added benefit of being able to save versions and go back to them if things go bad. My modern equivalent of a camera is ArtMatic. Instead of searching for interesting subject matter and trying to find the right way to capture it, I search mathematical parameters for interesting algorithms. When I find one, I can “mutate” it until I find it aesthetically pleasing, then explore all its nooks and crannies.
The Rogues Gallery series is a collection of “one hit wonders” of my ArtMatic explorations. While each one is an interesting image, moving ArtMatic’s “camera” around didn't yield anything much different.
