I have a couple hundred JPG files of different aspect ratios. Hardly

because that is the standard and cheapest, and will fit into the most
common albums.

So I'm wondering if anyone has suggestions on how I can run a few
hundred pics through a software that only pads the pic with blank
areas to achieve an aspect ratio of 2:3.

That is a relatively simple task using ImageMagick
tools... if of course you are familiar with them and
with writing batch files.


I did do this through a Photoshop action when when I was
making heaps of flash presentations.

The image was placed on a black background, and made to
fit. Had one action for Vertical and another Horizontal
images. Batched whole folders.

I do it with a shell script on Linux. It uses /exiftool/
to determine the orientation of an image, and adds an
option to the /convert/ command to first rotate the image
if necessary, then resample, and then add the back ground.
