I'm very into photography and would have many tips to share, but I don't really feel like writing anything down, right now, other than this: If you point the camera towards the sun - if the camera has an eyepiece, do not look into it as that can damage your eyesight, quickly; especially if you use the zoom. Also, otherwise, if you point it towards the sun to take photos with the sun present, keep the camera towards the sun for very brief periods. Longer periods can damage or melt the shutter, and even destroy the sensor. If you are composing a landscape shot, for example, with the sun a part of it, then keep the lens covered until just before you take the photo. Do not fret taking photos with the sun in them, though; just take precautions and do not waste time when being about to take them, and let the camera's sensor cool off, for a bit, by not taking new photos with the sun in them, too quickly.
Also, if you take landscape shots, use the timer to avoid losing sharpness. If you use an SLR/system camera, you may also want to activate mirror lock-up, for optimal sharpness.
