If you have an 8" x 10" photo that you want to crop, but you want the resulting size to be 8" x 10", you set your crop tool to 8" x 10" in the width and height boxes and the image – less the parts you cropped out – will still be 8" x 10". The image will not be smaller.

If you did not specify the crop dimensions when applying the crop, the image will be smaller.

If you have already done this, and not saved a copy of the pre-cropped image, you can bring it back up to 8" x 10" by resizing the image. (Provided that you cropped in a 2:5 ratio) There will be some loss of quality, but it may not be noticeable.

btw you should specify the resolution in the box aswell

BUT, there will be fewer pixels

If you did not specify the crop dimensions when applying the crop, the image will be smaller.

The only difference is the dpi setting, thus the ‘size’.

NO loss, if all you set is the dpi – same as the crop tool does after it removes the unwanted area[s].

IF you resample and try to generate new pixels, there’ll be some changes, but that depends upon the amount of cropping.

Cropping a 4×5 turtle from an 8×10, means you will have 1/4th the original pixels and thus the image will have less apparent detail when printed at 8×10. Still the -=same=- amount of detail as you started with, just that you’ve made it bigger – similar to printing the 8×10 at 16×20.

You really want to confuse the guy with this? He wants to crop an 8" x 10" to 8" x 10" by deleting unwanted extra area. The above does that. Assuming the original is sharp, he has a sharp new image that is a better composition.

Yes, but it won’t have the same amount of information, therefore it won’t be of the same quality, in precise quantifiable terms. However, if the original is sharp enough, the difference may not be discernible to the average naked eye.

It’s kinda like HDTV. Most people can’t tell the difference between 720p and 1080i although there is a quantifiable difference.

As with -=any=- resolution, the viewer’s distance from the display plays a major role.

A cropped original that would have printed at, say, 400 dpi, now printing at, say, 250 dpi is still close to the resolution of the medium.

A viewer at 10′ can hardly discern the details between 720p and 1080p. Note that 1080i is actually LESS vertical resolution than720p !!!

Now, put on a 15′ x 26′ sheet, then the audience can see the differences between 720p and 1080p.

Let me say thanks for all the above information from all of you. Now I have one additional question, if I do a crop as suggested to retain the 8×10 size should I put the same resolution in the resolution box at the top as I am starting with before doing the cropping? Thanks.

Depends. Are you going to print the image or use it on the web? Crop at 240 to 300 if you print, at 72 to 100 if you will use it on the web.

I am going to print it as an 8×10 so when I started it had a p/i of 311.5 so when I crop it as the 8×10 should I put in the resolution as 300? Thanks Tony for the help.

There’s a point beyond which a higher number doesn’t result in a better image. Anywhere between 240 and 300 is recommended for print, but you won’t reduce the quality by using 311.5. The file will just be a bit larger. Use 300 or 311.5. Either will work.

The you will resample and attempt to -=add=- information. The amount added would be dependent upon how much you’ve cropped.

You may or may not see the artifacts.

Best question is what are you going to print it on?

Fuji Photo or inkjunk?

Frankly, I’d crop using a fixed ratio in the marquee, then see what size you get. Then use the Image Size to set it for 8×10 WITHOUT resampling clicked.

IF the resultant dpi is more than 240 – I’d leave it alone and make the print.

No … now you have some bastard interpolation as the original setting was 311.5 and you’ve cropped and resampled to another dpi.

Then the printer’s going to have a go at the pixels to fit its capabilities.

In short potential for a discernible difference.

All you need to do is using the CROP TOOL then you will have 100% crop no matter what size you crop.
