Zach offered some excellent suggestions. I’d like to add one, the Kodak Guide to Photography. We called it the Kodak “Bible” back in the day and it’s probably the best basic photography book you can buy.
Johnrstrouts,
The image quality difference can be dramatic between a 6mp SLR and a 6mp point and shoot. Most point and shoot dit cams use a sensor that is considerably smalller then a comparable SLR. This means, even though they are capturing the same mega pixel image size, the larger sensor on the SLR is going to produce an image with much better overall resolution and sharpness.
As an example, I have an HP 4mp p&s that I take out on the creek with me for snapshots. It produces a file in its best mode of 540kb. My Nikon D2h is a 4.5mp camera and its file size is 2mb. That’s nearly four times the file size of the HP.

“First, make sure you have a full charge on your battery. Set the camera to manual mode and the shutter speed to “B” or bulb. USe a locking remote release cable and open the shutter. Now the mirror will be open and you will be able to see directly into the anti-aliasing filter and sensor. Take a bulb blower to remove any loose dust or impediments first. Keep the camera turned upside down during this. Then, take a lens pen set (a set usually has two lens pens – one small and one large) and clean the filter with the large lens pen and then the smaller one for the corners. Take the blower and blow clean again.”
Good idea, but really doesn’t solve the problem, just makes it better.
When you lock the camera open in Bulb, you are creating an electrostatic charge across the sensor. By creating a charge, the dust really won’t come off the senor, it just moves around. Nikon and Canon both have a sensor cleaning mode built into the custom functions, but you have to hook the camera up to an ac adaptor to perform the cleaning. In the cleaning mode, the mirror rises but the sensor is deactivated to stop the static charge.The Bulb cleaning will help temporarily when you have big dust particles in the middle of the frame but your best bet is to send your camera out one a year for a factory clean, lube and adjust. If you attend photo seminars or shows that are sponsored by the camera manufactures, many times they’ll have a tech at the show to clean cameras and perform minor repairs (I have mine cleaned at the National Press Photographer events I attend each year).
