What is the best way to crop a photo and not lose pixel quality? I shoot on 10 Megs.

Thanks.

Are you asking - Crop or reduce image size?

I want to crop to get rid of all background. As in cropping a flower.

Thanks,
Sam

This will not reduce the quality of your shot - just the size of shown area.
In Photoshop when I open - image> image size
a box opens up that give you the choice of either just changing the dimensions and/or the pixels/quality you never change the quality unless you want to for some reason such as Email or posting in some gtroups limit size.

Check out the crop edge slection strength _ % _ by adding 5 thru 20 ( more or less depending on your likes)you get a blurred edge to the crop rather than a sharp edge - makes a nice copy > past on a new colored background then frame it.

I noticed my picture size was 6.65 Meg and after cropping
it is 65.5 KB, and the picture is like a large thumbnail. Is that normal?

No, you're doing something wrong, unless you're cropping 99 percent of the image out. Can you post samples of the original and cropped images?

Let's say you have a 4" x 6" photo at 200 DPI (dots per inch). You decide to crop to only one quarter of the photo. At 200 DPI, you now have a 1" x 1.5" photo, and you've discarded three-fourths of your pixels. If you now want to print that reduced image at 4" x 6", the DPI will drop to 50 DPI. You can force a higher DPI (at least in Photoshop), but you will lose a lot of image quality in the process.

It all depends on how much of the original you cropped out. It's entirely feasible that a 6 MB original could get cropped down to 65K. What you have to remember is that the more you crop out, the lower your 'upper limit' to enlarging and printing is. If you find yourself cropping too much of your original, you may need to get closer to your subject next time. Without examples, it's hard to give you a definitive answer.

Are you going from RAW to JPG?

This is where you are going to get the answer you want -from fellows like this who know the tec. stuff I ignore most of the time. - keep answering thier questions and asking about things you don't understand.

I think I got it, I was cropping with windows 7 live photo.
I went into PS 10, and cropped the photo. Than when I saved it I slected save in 8x10 size.

Is this correct?

Are you shooting in RAW? What are you using for post processing? What is your full size image? What is your final, or cropped, size?

That may indeed be the answer. My first thought, was that perhaps you had resized the pic inadvertently, which could reduce your megs signifcantly and produce a thumbnail on your PS 10 screen (although when you subsequently pull it up in Windows, it will be full size, with no apparent loss in quality.)
