One of my other hobbies besides shopping is photography. It does give the added benefit of all the extra shopping but it can build up in cost. However most people do not need to go into exorbitant expense as most are into point and shoot photography. This is why digital cameras are fantastic, you point, you shoot and you can see your results instantly. Also if you are not satisfied you can shoot again and again.
There are a number of things to look for in a camera but this is dependant on what you are after. However, in digital photography the main feature is pixels. The reality is that most cameras today have sufficient pixels to provide decent photographs. A lot of cameras are nowadays coming with 10 Mega Pixels or more. The reality is that anywhere in the range between 1 and 10 mp is good, though I would aim for between 5 – 7 mp.
