How do I resize photos without losing quality?

Question

I have lots of photos that I would like to enter into competitions and upload to online photo libraries but the rules state that photos should be smaller in both dimension and file size than mine actually are. I have tried to compress with microsoft picture editor but then they are too small and if I try to make them larger/small manually, the picture distorts.

Please can some explain how a dummy like me can get this right?! Thank you!

Pixels are the smallest picture elements that the computer has recorded to make up the picture. Almost all digital photos are recorded in a format called JPEG. These are recognised by the .jpg extension after the file name. When a photo is made smaller (as distinct from 'cropped') it can only be done by removing pixels.



Sooner or later this will inevitably lead to clashing when pixels from totally different colour and intensity butt against each other. The result is mis-matching parts of the picture; very similar to what you see if you fold a pleat into a printed picture. The affect may not be so bad or abrupt as you'll get by folding a pleat but if there are enough mis-matches then it will still look pretty bad.



To re-size a photograph without getting these affects at all is impossible. But the better quality editor programs are able to do a good blending so that the disjoints are less evident. It needs some pretty nifty code writing on the part of the writers of these programs, that's why they cost more.



You really need a good editor like Adobe Photoshop or similar. These cost a bit more that the cheap ones that come bundled with computers but they have the ability to smooth out disjoints very well when pixels are removed. Photoshop also allows you fine control over the dimensions of your re-sized photo. Note that these programs are very versatile and so are slightly harder to use than MS Editor, but much more rewarding if you're going to do a lot of it.



If you re-size the photograph to make it larger then the good editor programs will attempt to fill in the gaps created when the pixels are separated (they can't change size). The better the editor then the more successful it will be in recreating the missing bits of the picture. But even these have their limits. You can't put information into a picture when it's not really there without producing a different sort of visible artifact. The good editors will let you enlarge to a greater extent than the cheap ones before it becomes too noticeable.
