Photo Straightenin/ cropping help

[PMan6766]

So I've been straightening a couple photos using the lens correction filter. The only problem that I have is that I usually end up cropping the picture instead of changing the scale, so that i can better center the photo. When I do this I lose the original/standard size ration of photos. How do I make sure that the new cropped image stays with the standard size ratio?

Thanks for your help

hold the shift key while using transforming handles, that should help

Under the Auto Correction tab there is an Auto-Scale checkbox.

Congrats on using that filter to straighten your images. I think it is the easiest method.

Now, your question. You say you lose the "original/standard size ratio of photos". The way I understand it, there is no "Standard" size ratio. The ratio of the original is dependent upon the sensor size of your camera. My Canon 7D has a 1:1.5 ratio sensor, meaning the length of the long side is 1 ½ times longer than the short side. A 4x6 frame is also a 1 to 1.5 ratio, 4 times 1.5 = 6. Short side 4, long side 6. Same thing with an 8x12. 1 and ½ times 8 = 12. So for those size frames my prints will fit entirely with no cropping.
Other frame sizes aren't the same aspect ratio, so the prints have to get cropped to a different ratio. A 5x7 is 1:1.4. An 8x10 and 4x5 are 1:1.25.
Hopes this helps and that I understood your question.
