[USER=115633]KerryEmery[/USER] - Sorry for the delay in getting back to you, but I've been trying to keep too many balls in the air. Anyway, I think I know what you are asking, but I'm not quite sure, so first, let me ask you a few questions then make a few comments.
1. You gave the sizes of your images in "Mb" (ie, megabits), not "MB" (ie, megabytes), or even better, "Megapixels". Since the first unit would imply very small images, I assume you meant, "MB", ie a typical image size from a 12 to 18-ish megapixel camera. Is that correct?
FYI, when one talks about the size of an image, since images come in different formats (eg, raw, TIF, JPG), and can be compressed by various amounts ranging from zero to factors of 5 or more, by far, the best unit to use to describe the size of an image is the number of pixels, or even the image dimensions in pixels, not the file size.
2. You also gave the intended final file size in Mb, so I'll assume that you are up-rez'ing each image by something like 3x to 4x in number of pixels along each axis. Is that correct?
3. You have a very nice 7890, but unless you have a good, color-managed workflow (including profiling the particular combination of paper and inkset that you intend to use), you could easily waste tons of ink and paper getting the colors to be exactly what you see on your monitor. For example, if you didn't purchase the optional paper spectrometer (spectraproofer, or whatever they call it), you should have your printer/paper/inkset profiled by a 3rd party service before you embark on what sounds like a major printing effort.
4. OK ... down to your real question. BenVista's Photo Zoom vs onOne's Perfect Resize / Genuine Fractals. From the tests that I have done, if your images are photographic in nature, ie, lots of textures that must be preserved, versus graphic art images (eg, out of Illustrator, with sharp edges that must be preserved as well as possible), then these two programs are about neck-and-neck, with maybe a very slight edge going to Perfect Resize.
On the other hand, if the images to be up-rez'ed are of the graphics arts variety, they are both good, but Photo Zoom does a noticeably better job.
I should also comment that I seen some claims by Adobe that they have improved their up-rezing. The last time I did a comparison between PS's native up-rezing and Photo Zoom was about 1.5 years ago, so something might have changed since then.
HTH,
Tom M
