I'm submitting some work to American Photo for their annual photo contest. I've had digital photos published before, but they're pretty specific about size and dpi and I want to make sure I get it right.
Namely, they want 350dpi and a size of at least 8x12. When I res up the photos from 180, going 5% at a time like I learned here, they get a little noisy but mostly they just lose sharpness. That's when I'm viewing them at full size on my monitor. When I take them down to 50% or less so they fit on the screen, they're razor-sharp and noiseless again. Will this be a problem? I guess this means the original wasn't as sharp as I thought?
Also, at 350dpi they have a "document size" of 7.5 by 11.6 inches, roughly... should I uncheck "Constrain Proportions" (using PS 7) and just make that into 8x12? It's certainly not a big jump and doesn't seem to affect quality further.
Thanks!
