Anyone using Genuine Fractals ? How useful you people find it ? Any plus points ? Any minus points ?
I use GF, and it does a good job of preserving sharp edge definition when you extrapolate images.
You can't take a thumbnail and blow it up to full size with decent results, but taking a good sized scan and enlarging it by 50 works OK, and I've taken 3.3 mexapixel shots and blow them up to 12x18 - a huge increase in size - and they have held their own.
I recently read something about acuity (the sharpness of edges) vs resolution (the ability to pull out fine detail.) It occurred to me that digital cameras are hi acuity / low resolution devices (relatively speaking.) Since GF cannot compensate for a lack of resolution (it the detail isn't there, it can't be extrapolated) but does a great job keeping sharp edges sharp, it is particularly well suited for digital shots.
