Does anyone not us auto white balance? I have used different settings to get it right.
A lot of us don't, because on digital SLRs, it is wrong a lot of the time. (i.e. any time we're not using natural light) For what it's worth, my Olympus C-750 Ultrazoom has outstanding automatic white balance. It was easily 5X better in any artificial light than my Pentax DSLR. By the reviews, this seems to be common to most DSLRs. Maybe Olympus is the exception though. To find out if you should use it, take some indoor shots without flash, at night. If you're light is supplied by conventional light bulbs (incandescent) then your pictures make look yellowish, sometimes even orangish. If you're shooting under fluorescent lighting, they may look greenish or purplish. If either of those is what is happening, your automatic white balance isn't working properly. In that case, you should manually set your white balance for the type of light you have. Usually, when you change it in the menu, you can see the effect in the LCD immediately.
Also a setting for vivid, normal, dull, B&W and septa. For color shots I use Vivid. Is this also a COMMON adjustment?
Vivid makes colors a bit brighter and more saturated than is natural. This usually looks great in landscapes, which is why people like Fujichrome Velvia film so well. In people pictures it can make people's clothes look like they're almost glowing, and give unnatural color to their skin. Normal might be better for people pictures, but try them both and see which one you like better. Oftentimes, normal is calibrated for skin tones. Dull usually adds nothing, and leaves things perfectly neutral. For product photos, this is sometimes desirable. For pictures of people & landscapes, the prints usually look very flat & dull. B&W is for black & white. Don't do this in the camera, unless it has the option of saving in color at the same time. You can do this in the software afterwards and still have the option of going back to color. Sepia is B&W with kind of a brownish cast, as if it is(an old B&W print that has aged quite a bit. It kind of looks old-timey. Sepia is my favorite for portraits. It has all the qualities of B&W, but without ever appearing cold like B&W sometimes does.
Noise reduction? Night shooting only? Is it a needed function?
It is needed for longer shutter speeds. Whether you have the camera do it now, or monkey around with it later in software is up to you. I just let the camera do it automatically when the shutter speeds drop below a certain point. I'm sure your camera can do this too.
Before you do, read the manual. On a digital SLR, you will not get everything your camera has to offer unless you do. At first, just look up the things you're curious about. Then play around for a bit, and look up the new things you've discovered, but don't know what they are. Then, spend some time and read the whole thing. (I do this on the train or during lunch at work) I used to not read manuals. I'm a smart person, technically speaking, but I found that I was only getting about 85% of what my cameras had to offer if I didn't read the manual. Also modern manuals are very well-written. Olympus has some of the best in the business, even showing a lot of sample photos. It really is worth your time, and then we don't have to retype the whole manual for you here. :blushing:
