i am going to buy a new digital camera as the one i use on my phone is crap and i want to take better pictures when i go abroad.what features are best to have?what are good camera makes?what card does the camera normally save to so i can print them off?
Most digital cameras these days use SD cards (and higher capacity SDHC cards etc). They can be bought very cheap now, a fast 16GB is around £20-25 or so, depending on brand, and will hold plenty of photos (and some HD video).
The best compact cameras available at the moment are probably the Canon Powershot SX230 HS (around £200) which has a 14x zoom lens and offers great photo quality, particularly in low light (for a compact camera).
The Sony HX9V is more expensive and also very good quality, although personally I'd choose the Canon myself.
The Canon S95 and Olympus XZ-1 are in a different league, image quality-wise, offering better quality all round, but lacking the large zooms of the Sony and Canon's mentioned above. They have the typical 4-5x optical zoom as opposed to 14-16X in the Canon and Sony respectively.
If quality is more important, go for the Canon S95 (or new S100) or Olympus XZ-1 (both more expensive but worth it IMO) but if you want a longer zoom lens (but still very good picture quality) then you can't go wrong with the Canon SX230 HS
Here's a link to a group test of compact zoom cameras that might help - Check out the comparisons of photos shot in daytime and night to see the quality difference between the different compacts. The Canon wins every time I believe, closely followed by the Sony:
