Originally posted by willis I have an older Canon P&S (Powershot A540) that lets me simply switch from 4:3 photos to 16:9 photos. Is there anything like this for my Pentax?
In a word: no. Various P&S's allow shooting in different aspect ratios: 1:1, 2:3. 3:4, 16:9, 2:1, etc. Your K20D is a fairly advanced dSLR built in the tradition of old 35mm film cams, which only have the 2:3 aspect. To fit a 2:3 photo onto a different-aspect desktop without torturing it brutally (the Procrustean Bed syndrome), you must do a little PP editing. You have these options:
* Shrink the image to fit the monitor in one direction, then display it as-is, with no stretching.
* Shrink the image much smaller and have it displayed as a tiled matrix. Ugh.
* Crop the image to the same aspect ratio as the monitor. Lose an edge or two.
* Letterbox the image - create a background layer of the monitor's aspect, then put your image on top of that and save the combination. Now it displays correctly.
* OR: Shoot abstractions such that stretching and torturing won't be noticed.
I wonder if there's software for running the background/desktop as a slideshow, with options for displaying pictures resized but unstretched? I don't pay much attention to such warez, but I'd be surprised if such didn't exist. Gargle for DESKTOP OR BACKGROUND SLIDESHOW and maybe you'll find something. Good luck!
