Aspect ratio change after rotation.

Why does the aspect ratio change an image after a 90 deg. rotation. It's OK if I wanted to make someone look tall and thinner, but that's not usually the case. I always have to resize the image to strech it back out to the original aspect ratio. This seems to happen on different computers and with different software.

Aspect ratio never changes with a rotation. It will be your perception based on a poorly configured display.

Calibrate your monitor at your favorite resolution. Use square and circle target images to make sure your pixels are displaying at 1:1.

If you have a traditional 4:3 aspect screen, then never run at 1280x1024 resolution. That's a 5:4 mode and is only displayed properly full-screen on an LCD. My immediate guess would be that's the resolution you're running. But as mentioned, whatever resolution, you need to calibrate to get your pixel ratio to 1:1 (ie. each pixel should be a perfect square).

I have an 18.1 digital flat panel and it is recommended to run at 1280 by 1024. Should I change the settings?

No. With flat screens you should never deviate from the recommended resolution. If you do the screen will still work but the picture will degrade significantly. I'd suggest you live with the problem. We all do. Just remember that the file from the camera is still correct. The only problem is the way the monitor displays. Printing will show you the correct ratio.

You are already running the correct aspect. Digital Flat Panels (DFPs, aka an LCD (Liquid Crystal Display)) come in various aspect ratios. 4:3, 5:4, 16:10 etc. Your 18" model is 5:4 aspect and shaped/sized to run 1280x1024.

The pixels are perfectly square and you will be seeing exactly what you'll be printing. People with CRTs (analog displays) that are 4:3 should not run 1280x1024. This does not apply to you. :) Anyone with a CRT that wants a similar resolution should be running 1280x960.

I run at 1280 x 1024 on a Samsung SyncMaster 900NF CRT. It has controls to change the horizontal and vertical proportions. I simply draw a large square in a graphics program (any photo editor will do), hold a ruler up to the monitor and adjust my monitor until height and width of the square are the same. Move the square to different corners of the monitor and check again. I once had to return a monitor that squished images on one side but not the other.

It seems that many monitor default settings give you a disproportionately wide display. That may be fine for text editing and spreadsheet work but it sure plays havoc with graphic design.

Your setup follows exactly what I suggested in one of the first messages. There are great target images and programs available for size calibration. However, by squishing the image on your CRT to properly display that resolution, you're not maximizing your display's width. You are in fact making your pixels smaller, but you could always increase your resolution if that was your goal (to 1600x1200 let's say).

I'd rather run 1280x960 if the monitor is able to render properly close to its borders on a smaller screen, and 1600x1200 on a larger screen. Just make sure to increase font size to a comfortable level so you don't damage your eyes. As has been mentioned before, Photoshop's ailing interface doesn't give you control over the size of most of its elements, including fonts.
