Im going crazy here. I want to maintain the 4:3 aspect ratio when cropping but my brain cant figure it out.
The only way i can do it is by typing 4 & 3 in the boxes to which photoshop then resamples my image to 4 x 3 cm and then i have to resize it. Can someone please tell me how to do this before i go all nuclear on myself. Im using photoshop CS5

I normally just enter 4 and 3 in the boxes like you say. What you need to rememeber is that it does NOT resample the image unless you enter a value in the 3rd box for resolution.

I only know of one way. Select the crop tool, leave all the boxes for dimensions and resolutions empty, and then select the entire image. Now, with the entire image selected, hold the shift key, grab one of the corners and drag it to crop. If you don't select the entire image first, holding shift will lock you into a square crop.

Select the entire image, then while holding down the Shift key, resize the crop area.

Why are you cropping to the 4:3 ratio?

Yeah, if you are doing this to a DSLR image the original aspect ratio is 2:3 not 4:3. This could confuse you if you enter 4 and 3 in the dimensions box and see your image being cropped off at the wider end!

Like was said, don't enter a resolution number or you can end up resampling the image. Or, like was said, hold down Shift as you drag the crop rectangle and it should keep the originsl aspect ratio or whichever one you choose to enter.

No, you're missing the point. Why are you cropping to any ratio at all?

You should only crop when you have specific reason to do so - eg printing. And only a handful of standard print sizes are 2:3, and even less 3:4.

I tried doing that for a while but then I figured it's kind of over-rated if I'm not going to be printing the vast majority of the images anyway, now I just crop to the strongest composition if all I'm gonna be doing is viewing it digitally.

Glad you figured it out though, it's very good to know and good to be aware of, whichever you choose to stick to.

Yes, but why?

I'm asking because I want you to thoroughly analyse your own workflow. Is cropping really the best thing to do? Have you considered the 8x10 problemexternal link which occurs from careless cropping?

I have noted what you guys have said and will take it to mind when processing in future. I am a beginner photographer. Just got my camera today so i still need to run in with all these issues. Im just so over the moon that i have learnt one thing for today that has been bugging me for months.

It's not too complicated, some people just make it that way.

Unless you're going to print, crop to whatever size / ratio you'd prefer.

If you plan on the image being printed, then crop to the appropriate ratio for the print size. 8x10 is obviously 4:5 ratio. 20x30 is 2:3. Clearly you can't provide the same image in every ratio without using borders, or re-cropping, so either provide prints only in sizes you're satisfied with or just accept the fact that in order to make every common print size, you're going to have to produce some strangely / poorly composed images.

Some online services (SmugMug, for example) will allow clients to perform the crop themselves, which I find very nice, since I'll get a sale, and the client can see what the crop is going to cause their final print to look like.
