Photoshop-blowing up a picture-question

how much larger are you wanting it?

12 by 12 is huge for that picture. Here is a stab at it.

It won't let me post the image. For some reason during the upload to image shack it's distorting the color. I can email it if you'd like.

I know it sounds weird... but run a "Glaussian Blur," with a setting of 1, then run sharpen. Should help.

But you are dealing with the pixels (or lack there of) that you have, so you are only going to get so much out of this original file.

If you need a great quality image... take the existing image and have it outputted to slid film (say 3 x 5), then have that slide scanned it at a übber high resolution on a professional drum canner, then you can print that image on any medium you want.

Might run you about $60, but it may be worth it... depending on how important this image is to you.

You need to have the original image (the sharpest one) scanned with a super-high resolution. 300x300 is pushing it for household scanners. (a print shop or photo lab may have a better one...)

There is an article that explains scanners:

The problem with blowing up a photo (or digital picture) that doesn't have a high resolution (or pixels per inch) is that there isn't anything to "blow up" if there are only a few pixels already there....that's why it's blurry when it gets stretched.
