I have noticed a few contaminants in some of my K-x images. especially in photos with a light-clear sky back ground. In the middle of the image there is an object shaped like a tipped over S and to the upper right a few specks. I remove these in my photo software but I would like to remove them from my camera. I just don't know what to clean. I tried the lens with a soft lens cleaning rag and blew off the image sensor after I removed the lens. But the contaminants are still appearing. Any ideas?
Also, a very good friend just gave me a used SMC Pentax-FA 28-200 Zoom lens. It is great over all, but I am getting many washed out photos on sunny days. I have the dial set to auto picture, but the wash out is pretty dramatic. When I shoot away from direct sun or in shade, then there is no problem. I am not sure how to eliminate this washout, what to do different. Any help on these two issues would be greatly appreciated. Thank you! - Mike

2. If you're getting washed out photos you are over exposing for some reason. Either your ISO is too high, your shutter speed is too slow, or your aperture is too wide open, or a combination of all 3. That's if it's something YOU are doing. If you are using one of the Auto modes, Av, Tv, Green, etc, be sure you have the lens set on A (you have to push the little button next to the A to turn the aperture ring all the way to A). If it is there and none of the above is true, you may need to clean the contacts so the camera knows where the lens aperture is at. If all that fails, check and make sure there is no oil on the aperture blades. If there is, then they won't close fast enough to give you proper exposure. For focusing and viewing purposes, the lens aperture is held open until you press the shutter release. Once you press the shutter release, the aperture blades are supposed to immediately close to your predetermined aperture (either from the camera or from the setting of the aperture ring). Oiled blades will prevent that from happening.
