Philosophy: these days, you can just go for the cheapest camera and get decent image quality.
- Search for a used 10mp+ camera for as little as $10, typically between $20 and $40 on Google or Ebay
- Make sure the camera has a continuous shooting mode so that when we send it into the air with the button mashed down, the camera will continue taking photos every second or so.
- Consider what kind of battery the camera has: when buying a used camera with a proprietary rechargeable battery, there is always a chance that the battery will be worn out and unsuitable for long flights of interval shooting. This is especially true if the camera is a very old model. The Canon A490 takes standard AA batteries which is helpful when simply being outside might prevent you from recharging the custom battery.
- Buy the camera!
