Sizing after Crop
RDOC
I have an image that is an 8''x10'' photo and I want it to remain that
size. It is an image of a turtle which has to much open space around
the turtle so I want to crop it to remove all that open space. Now
when I crop it to remove the open space the size of the photo becomes
smaller.
What is the proper way to now enlarged this cropped image back up to
the 8x10 size without causing any loss of quality in the photo? Thanks
for your help.

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.

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.

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 8x10 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 8x10 so when I started it had a p/i of
311.5 so when I crop it as the 8x10 should I put in the resolution as
300? Thanks Tony for the help.
Rob
I would and you interpolate it up to the same pixel count.

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.
