Every time you save a “lossy” format like a JPG image, you lose a certain amount of information, making the image less clear. You don’t lose any information with a “lossless” format like PNG no matter how many times you save the image.
When you are done editing, you can re-
Confused over what size an image needs to be for print use? Join the club!
The short answer is this: take the width of the digital photo in pixels and divide by 300: that's how wide (in inches) the printed image will be if printed at 300dpi (dots per inch). Do the same with the height.
For instance, an image that is 1800 x 1500px will print at 6 x 5” at 300 dpi. Or, to put it the other way around, if you size an 1800 x 1500px image to 6 x 5” (when you paste it into a Word document, for instance), the image will print at 300 dpi quality.
What about the image's resolution -
So what can be done with print (film or non-
Once a print photo has been scanned into the computer, a graphic editing program such as Corel Paintshop Pro can be used to clarify and enlarge it. Of course some things, such as excessive spotting or silvering of dark areas of background, can't be completely fixed, but even they can be improved.
If the photo is scanned into the computer at a high resolution (such as 600ppi), the resulting digital image can actually be printed out larger than the original, which can be a great help with very small photographs.
Besides removing faults like spots, stains and tears, digital editing can be used to straighten an image, correct colour problems, and crop out unwanted features.
When scanning a print photo into the computer, use the highest resolution you can -
Not every print photo can be corrected, nor can all photos be made suitable for all uses. For instance, a very small print photo can't be blown up beyond a certain point. Almost any photo can be made more usable, however, by digital image editing.
Print photos tend to deteriorate over time, and are subject to getting torn, bent, and stained. Once they are scanned in, digital image editing can be used to create clearer, better pictures. The edited images will also preserve your photos in a useable format.
You can do some things to help keep your print photos from deteriorating, of course. To find out how to preserve film photographs, read How Should I Store My Photographic Prints?
If you are using images for anything, you need to be aware of -
If you created the image yourself (and did not copy it from a copyrighted source), you own the copyright.
If the image is in the public domain, it's not under copyright and anyone can use it.
If the image creator has made the image available under a Creative Commons license, you can use the image under the specific terms of the license.

You'll find detailed information on copyright and Creative Commons licenses on the Copyright page.
If the original image is in a “lossy” format (like a JPG file from your camera), first save it to a “lossless” format like RAW, PNG or Paintshop Pro’s PSP format. That way you can edit the image and re-
