Yes, we have accepted some digital photos very recently. It's becoming a matter of necessity, as more and more people trade in their film cameras for digital ones. Of course, our usual photo-quality standards for sharpness, contrast, depth of field, colors, etc., continue to apply.
We're probably still saying "thanks but no thanks" to a larger percent of submissions with digital photos than we do to ones with film photos. It's still better if you can submit prints/slides/transparencies, but we won't reject digital photos just because they're digital.
Digitals seem to work OK for the close-up in-process shots, but it's a stretch for current consumer-grade cameras to produce good, large article lead photos. Given the rate at which the price of pixels is coming down, that may soon change.
I should add one new word of caution about digitals: no retouching, doctoring, or "Photoshopping"; the photos we run in the magazine must show the model
exactly as the modeler built it.
Hope this clarifies things. Happy modeling!
