Does anyone have any useful references for photographic image printing
algorithms?  A printed image is typically at a higher resolution than the
digital image data.  For example, a 1600x1200 image will seldom require
magnification for screen display purposes, but the same image ...

Hello.  Is there some way of taking a 72-dpi image and somehow
squeezing more detail out of it?  I've got a photo that was done at 72
dpi but the publisher needs 300 dpi to work with.  As a newcomer to
digital photography I tried printing the 72 at highest quality and then

Hopefully someone can help with this somewhat obscure problem.
I've got a bunch of panos to stitch together and since I don't want to
spend the next week picking out control points, I thought I'd give
Autopano-SIFT a try. It seems to be working OK from the OS X Terminal

I've just noticed that IV is not displaying thumbnail views of any PSP
or PSPimage files.
Could someone please check whether this is possibly a flaw in the
latest version 3.98? If not, then it's down to my system or settings,

Right now, I am working with a pretty cheap Kodak digital camera, using
series of photos to make panoramics by stitching with Hugin/Panotools.
The camera has two particular annoyances that make this more
difficult...

I'm looking for a compact wide-angle digicam.
The Canon S60 seems nice. Offhand the extra resolution of the newer
models seems pointless. (Or am I missing something?)
Anyone know if the startup speed and focus/shutter-lag speeds are

I can not figure out how to take video clips that I can see! All of my
video clips are dark. I read the maual but can not seem to figure it
out. Can anyone please help?

I've had a few digital cameras but nothing very fancy, for the past year or
so I've been using a small Canon Ixus 500 which has done a pretty good job.
However, I would like a camera with a few more features, especially improved
zoom and more control over manual focusing (there ...

At some rare occasions I could use some extra "reach" on my 5D with
100-400mm IS L. I probably got a little pampered with the extra "reach" on
my EOS Rebel (1.6 factor).
So I was thinking of buying an EF 1.4x II extender.

I am currently getting my 4x6 prints made through Sam's club, and I'm
satisfied with the price and quality.  I've not tried other services
however, and I'm curious for opinions on some of the others out there.
Thanks!

Is there a way of adding a "multiplier", to the focal length, so that the
35mm equivalent is shown?  I've searched the help and FAQs without success.
TIA,

I have the S5600 (5.1 mp) camera. It shoots in RAW mode as an option. I
recently took a few pictures in the RAW mode and edited them in S7RAW (a RAW
file editor and converter), then saved them as 95% quality JPEGs. This saved
just over half the original RAW filesize. They went from ...
