CS3 Cropping and retaining resolution
Would anyone be so kind as to lead me through the process of cropping an image in Photoshop and preserving the original resolution?.

It seems that when I go in and crop (and sometimes adjust the levels) I get an end result that looks like it has less resolution than the original image..

Could it be that I am doing a "save as" (to leave a pure copy of the original image) and that is the reason? (Saving to jpg.?)..

I am shooting with a D2x if that makes any difference. The resolution should be quite good, but they don't look so good after I get done "fixing" them..

Thanks in advance for any help...

A crop, by definition, removes pixels. Therefore you must lose resolution (pixels)..

Does "resolution" perhaps mean something different in your mind?.

Probably. Things work differently in my mind. Perhaps resolution is the wrong word..

First of all, thanks for the quick reply..

Let's try this. The original image looks crisp and sharp. After a modest crop and a save, the image looks more grainy and dull than I think it should..

Perhaps it is normal, but if I am shooting a 12MP camera, shouldn't I be able to crop and end up with an image that is nearly as crisp as the uncropped image?.

I know a lot of this is subjective, and I'm probably using the wrong terminology...but this is the beginners questions forum and I am......obviously....painfully.....very much a beginner...

You should not see any change in image quality (sharpness, resolution,tonal range, etc) when you just crop image in CS3. So you may be doing something, perhaps unknowlingly, in processing. Do you use crop tool? if so, do you specify resolution? Do you start with Raw image, if so do you use optimum settings in Raw converter? CS3 is a complicated program and it is easy to get things wrong. Also, do you view your images at the same size on your monitor. Images look different if you view them at different percentage size. Particularly, if the image is not tack sharp, image viewed at 16.67 percent will look sharp but fuzzy at 100 percent size.

Experiment. Sandy..

Sounds like either you are cropping and saving a JPEG or not viewing the image at 100%..

If you are shooting JPEG, you need to convert to a PSD or TIF before doing any modification to the image. Then you won't be degrading the image each time you modify and save. If you're not viewing at 100%, you can't make statements about how the cropping degrades the image because you're not viewing the image properly..

Additionally, every change in size softens an image and Unsharp mask is then needed to bring back the clarity.Larry Berman
