To begin with, I'm curious about your process. How much does technology, such as photoshop, play into it? Your work seems like the marrying of old master techniques with a modern edge of image merging. How do you choose what images to use together? Are there certain criteria they have to share, or are you looking more for images with distinct differences?
I'm a big supporter of the marriage of technology and arts. Visual artists have loads of helpful tools at their disposal and should be taking advantage of them, or at least testing the electrified waters. It's important to shake the stigma of that integration, embrace the inevitable, and live in symbiosis. Artists since the renaissance have been utilizing modern technology to further their careers and abilities, such as the camera lucida and camera obscura. Caravaggio, Vermeer, Ingres, so many more. I've been integrating technology into my practice for a while, from the use of photoshop to projection to prints on canvas, but I do have a preferred few. In the incubation stages I use photoshop, whether it be setting the actual composition of two images to make a double exposure or a simple crop and color correct. I also use photoshop's color picker to find the simplest mixture of color. This is my favorite tool because it makes my colors very clean, no muddiness and almost luminescent.
My image selection process isn't very esoteric. The most prominent characteristics I search for are beauty and anonymity. I have a proclivity for the lucid and ethereal, but careful to avoid images that appear too gaudy. I try and match images that are diverse but still share a important quality. This formula varies with each painting, so I can't really pin point any prevalent visual theme.
