A lot of people ask me this a lot and I really don;t have a good answer for them.

Does anyone know if there is a program or if Photoshop can be used to crop a certain area of a picture and than magnify cleanly with no pixelation?

I can't think of any program that can enlarge, without pixilation.

You have just so much information stored in those images.
When you try to enlarge an image, you're basically pulling the pixels apart, and the program has to "guess" what is to occupy the additional space between the pixels.
Most programs aren't very good at "guessing".
I imagine, there are some high-end (expensive) image editing programs that are better at "guessing", than other programs, but I can't say for sure.
Even then, I'd imagine the results would be mediocre, at best, depending on the level of magnification.

Photoshop does an 'alrighttttt' job of it.
you can buy plugins for photoshop that will do a better job though

crop the area you want magnified and hit ok, then go up to Adjustments >> Image Size and change it to how you want there. You may have to click constrain proportions to keep it even though :thumbsup:

try not to overdo it though.
