Several people recently have taken digital photographs of sports events, etc., but have been disappointed with the the results, and have asked for advice.

This is an overview of what to do.

First, there are several settings you need to change, and each has its costs and its benefits.

1) Resolution. It is a fallacy that more megapixels means better quality. The size of the sensor is a serious influence, and is why 'improved' versions of a camera, from 10 to 12Mp, actually receive lower quality results. However, they sell cameras so the manufactureres still do it. The pixel size is microscopic, and cramming more into the sensor just increases noise and other artifacts. There are 20+Mp cameras, and the quality is superb, but they have big sensors to match their big prices. As a guide, 6Mp or 8Mp is fine.

2) File size. Memory cards are cheap. For example, a 4Gb card can be had for about £30. If you reduce the file size to get more pictures on a small card, they won't be worth using: it is false economy. Get a couple of memory cards, and regularly save the ones you have to your computer, then format the card. Of course, it's a good idea to do a backup of your files, in case the hard disk fails. It may be under 'lifetime' warranty, but that will only replace the disk, not your memories.

File size is also related to compression, which by its nature throws information away. If you use maximum compression you will be able to save hundreds or thousands of photos, but they will not print well and you won't be able to zoom in without losing quality. Once again, as memory is so cheap, I would suggest that you use top quality.

Another slight price to pay for this is that, depending on the camera, they will take longer to save, so it may be a few more seconds before the camera is ready for action.

3) Shooting Technique. If you have a camera without a strong zoom, don't take pictures if the players are at the far side of the pitch. Wait until they come nearer. If your son is scoring a try at the far end, of course, take it as a record shot, as you would do if a Martian was landing and it was the only thing you had. Anything is better than nothing. The other thing you should do is to get low. Crouch down if you can, or if you'd rather not because of age, smart clothes or disinclination, set the camera to its widest zoom and shoot from the knee, just pointing it in the general direction. You'll be amazed how many good, though admittedly lucky, shots you will get. Further, in a crowd set the camera to its widest zoom and hold it high above your head. Above all, decide what you're taking and make sure it is big.
