I have been recently evaluating image enlargement using Photoshop CC
(detail preservation), Photozoom Pro 6, and Perfect Resize. This is
all on a 64 bit Win 7 system on a Dell Inspiron laptop. Had some
initial problems with Perfect Resize as my laptop's video drivers/ card
wouldn't support it, so I had to install on my desktop with supported
card.

After using all 3 programs, and from what I could find googling these
seemed to be the best enlargers at present, I don't really find any
significant difference. In fact, so far, just barely above the age old
bicubic resampling the original Photoshop and other programs offered.

Photos I'm enlarging are generally 16 bit TIFF that do sometimes have
artifacts to start with, but I can sort of negate these artifacts with
any one of these three programs. Enlargements have generally ranged
from 200-500%.

Overall, I'm not all that pleased. Photozoom costs quite a lot, not
sure about CC and Perfect Resize. Perhaps I'm not using the correct
settings, although I have experimented and customized a LOT of them, or
perhaps there are better enlargement programs out there, which is why I
turned here.

Thanks, in advance, for your replies.

For enlargement after some cropping, the current releases of Photoshop
CS6 & CC both use rsizing which does a very good job of bringing even a
sev crop up to normal sizes and slightly.
For extreme enlargement of 200%-500% such as you have been talking
about, I have always got good results from Perfect Resize. However, I
will add the caveat that I was working with RAW image files, or TIFFS
of PSDs which where producd directly from the RAWs.
You talk of the TIFFs you are enlarging having artifacts to start with.
Why? Were they originally JPRGs converted to TIFF, or were they scans
to TIFF?

Then there is an application I haven't used, because Perfect Resize
meets my needs, Alien Skin's "Blow Up".
