Perhaps I haven't noticed this before...
Because of emminent system failure, I purchased a new PC with Windows7 (upgrade (?) from Windows XP) and then upgraded Photoshop to CS5 from CS3. However, I notice that when I rotate a "landscape image" and make it a "portrait", I find that the image appears to be cropped automatically, rather than retain the aspect ratio of the "lanscape image"; it appears that the former height in the landscape, becomes the new height in the portrait . I think it has something to do with the aspect ratio, as manipulating this seems to alleviate the symptom somewhat. It also appears to be present in the other image viewers that are not Adobe. Can anyone explain this and direct me to information on how to correct this problem?
...when I rotate a "landscape image" and make it a "portrait"...
How are you doing this, exactly?
You need to rotate your entire image document.
Try this: Choose Image - Image Rotation - 90 Degrees Counterclockwise (or the appropriate choice). What do you see?
I've tried that and the image is still "cropped". I've also made the image a layer, made the image canvas larger, then tried to rotate the image as a transform, with the dimensions locked. It also crops when I rotate it that way
Can you please do screen grabs before and after, save them as JPEGs, and attach them to a post here?
You don't just need to zoom out, do you? Use the Zoom Tool to change how much of the image you can see. The Control 0 key combination will make it all fit.
I believe I have determined what was happening by thinking about my question after I posted it. As the "cropping" was system wide, I realized the problem had to to do with the system and not Adobe. So I looked at the aspect ratio of the monitor by looking at the vendor's specs for it on line. The problem went away when I changed the graphic card aspect ratio to the correct ratio for the monitor
