Genuine Fractals is the program. It is a method of interpolating images to
larger sizes that is supposed to hold up better when making large prints. It
is supposed to give a smoother interpolation. It uses some sort of fractal
algorithm when doing the interpolation that is supposed to retain more
sharpness in the image. I don't know if it might develop artifacts in the
image when doing so or not.
I have never used the program. Usually I am interpolating down rather than
up. I think it may also be more popular with people using digital cameras.
If I interpolate up in Photoshop I use Bicubic interpolation.
My guess is that it might only be helpful when you need very LARGE negatives
and have a small file. Just depends on what you need.
If you adjust your image to 360 ppi, and the image is big enough to make the
size negative you want, then you wouldn't need to interpolate up. 360 ppi
should give you the smoothest negative.
Perhaps there is someone on the list that uses it and can elaborate more on
the advantages and disadvantages of the program.
