First of all, DO NOT use Q-tips or any other product similar. The fine strands of cotton can scratch the lens surface. It is recommended that you purchase a camera cleaning kit. It is a good investment to keep your camera looking and taking pictures like new.
(ednote: one of the best investments one can make is to get a skylight or uv filter (if possible), and just keep it on all the time. If you mess up the filter, you can always replace it. Much less expensive than a new lens!)
(ednote2: another convenient way to clean a lens is to use a LensPen. These cheap (~10$) tools have bristles on one end, and a moisturized cleaning pad on the other end. First, brush off any loose debris from the lens/filter, then gently in circular strokes wipe the lens/filter using the moisturized tip. Once the moisturized tip no longer works, invest into a new lens pen.)

Most consumer digital camera CCD's allow infrared or near infrared light(NIR) to pass through the lens because the hot mirror (a filter for removing Infrared Light)is not of high grade quality,so equipped with a in-expensive filter such as the Hoya R72 or the Wratten 89b you can take dramatic shots using non-visible light from the sun or other light sources.
  
What you need for infrared photography:
•A camera that is sensitive to NIR/IR
•An IR Filter
•Tripod
•Image Editor
•NeatImage (not required but helps quite a bit - Demo Available)
The test
A quick and easy test to find out if your camera is even remotely capable of infrared photography is the "Remote test". Turn the camera on and power on the LCD. If you have an SLR then you don't have an LCD to look at, just take a photo and look at the photo on your computer. Turn off all the lights (closets & bathrooms work pretty well). And point the TV/VCR/Cable remote at your camera's lens. Press a button and see if the LCD displays a white/red/orange color coming from the remote. If there is something chances are your camera is capable of infrared photography.
Some cameras that are great for IR photography:
•Olympus C-2100UZ
•Olympus C-2000Z
•Olympus C-2020Z
•Sony 7x7
•Minolta cameras
•Older Nikon cameras
•And many more...
The technique
The general technique for infrared photography is hard to describe. The obvious suggestion is to shoot vegetation. Green healthy foliage is usually excellent. But it can obviously be almost boring as just about everyone tries to photograph greenery. Spicing up the photo with big/interesting structures makes the photo a little different. People can introduce an interesting element but they have to stand/sit still as the exposure for infrared photos is usually long.
Using a tripod is at times essential depending on the sensitivity of your camera. The big problem with shooting vegetation is that wind can cause movement of trees blurring your photos. To get around this it's best to shoot on calm days. Best IR is during the morning and late afternoon hours, it's when the lighting is most dramatic.
Depending on your camera it is possible that you will get different tints to your photos. For example, a C-2040Z will have a deep red tint to any infrared photo and the exposure time will be quite long (1 second or more). A quick and easy way of getting rid of the color cast is to use the B&W mode of your camera. A lenghtier process is to use an image editor such as Photoshop. The advantage of using an image editor is that you have much more control over the image manipulation. Playing with channels and gradients is a good way to alter the appearance of your image.
NeatImage can help you get rid of excessive noise in your photos caused by long exposures and warm temperatures in the summer. It's not required but once you see the difference you will ask yourself why you have not been using it all along.

One of the most simple and effective ways to prolong battery life is to not use the LCD screen. This screen has a backlight and will drain your battery. Get accustomed to using the viewfinder.
Also, save your flash! Learn to know when flash is needed and when it isn't.
(ednote: Keeping your batteries warm in cold weather also prolongs battery life.)

Yes, possibly...
First, you must have a card reader attached to your computer that shows a physical drive.
Second,download a image recovery software program such as
Data Rescue and follow the instructions
Some Data Recovery Software will also restore images, check with the software author as to what type of files in is capable of recovering as some only recover text files

3 basic ways, But first,, Understand what red-eye is
Red eye is when the light from the flash goes into the eye of the victim , uh, I mean subject, and bounces off their retina (The "film screen" in the back of your eye). The blood vessels in the retina turn the reflected light red, which is, in turn picked up by the camera.
1) Red-eye reduction thats built into the camera. This shines a small light, or fires a strobe at the subject that forces the subjects iris to shrink down, thereby reducing redeye.
2) Have your subject look a smidge to the left or right of the camera (just hold up a finger with your free hand about 8-12 inches off the side of your camera).. Or, move your flash off the camera. (Slave strobe or PC triggered strobe, But these are expensive and bulky). Just having the subjects eye not looking directly down the lens of the camera, will reduce the light reflected off their retina showing up on the final image.
3) Make a Bounce diffuser. This one is easy.. rotate your flash head up towards the ceiling, Now tape a white business card to the back of your flash, overhanging where the light comes out, and Viola.. A bounce diffuser. The light comes out of the flash, bounces off the white card, and the ceiling and evenly illuminates your subject, while reducing redeye.
Hope this helps you, Give these ideas a try, and above all else, Have Fun!!
addendum by your friendly neighborhood editor... take a look at Red-eye control for a somewhat more elaborate explanation, as well as additional hints...

If you're trying to take macro shots or time exposure shots, professional photographers will recommend that you use a cable release or remote control to release the shutter. The smallest vibrations can blur your whole picture, even if you've got the camera mounted on a tripod.
But what if your camera doesn't have a threaded shutter release for a cable, or a remote control? You can use the camera's self timer instead to get the same result. Almost all cameras have a self-timer, and some digital cameras even have a special 2-second timer in addition to a longer 10-second timer for this purpose.
Another thing to try to minimize vibrations at medium speed shutter speeds (1/10-1/30th of a second) is to stabilize yourself against a tree or something similar. Breathing and the way you press the shutter release is also very important. I found that I got best results when exhaling and holding my breath. And holding the shutter release button also helped me stabilize the camera.

This happens sometimes, Usually because a picture gets framed right after printing it. The ink may be dry to the touch, but it hasn't "Cured" yet. Give an inkjet print at least 24 hrs to cure on the paper, before putting it in a frame.
Also: Using a mat board helps (Matting). A mat board is cut out in the middle to show the picture, but fits into a larger frame.. Mat boards can be 1/8" and thicker, This serves to keep the surface of the print off the glass, and thereby reduce the chance of the image sticking to the inside of the glass..

Warm/dead pixels are imperfections in the CMOS/CCD device of your camera. They are usually a different color from the surrounding pixels in a photo, mostly visible in dark parts of the photo.
A good way to test your camera for warm/dead pixels is to take a photo with the lens cap on. Or, if you own a camera that doesn't have a lens cap or the lens cap will interfere with the lens then go into a closet or bathroom with the lights off (complete darkness) and take a photo. The longest exposure you can get your camera to go (manual mode might provide longer shutter speeds) will show you more warm/dead pixels.
Then you can use this application to analyze the image for a detailed report.

Figure of Merit is a term used to describe the comparison of digital cameras with varying zoom and pixel counts and their ability to maximize the number of pixels on the subject.
This relates to the common question of "Is a 5 megapixel camera with 3x zoom better than a 2 megapixel camera with 10x zoom?"
What happens is that with a longer zoom you can sometimes place more pixels on the subject than a higher resolution camera but with less zoom.
Here's a great explanation and comparisons on Figure of Merit

First things first: Do not use a flash!!!
Stars are: a) a light source (you wouldn't use a flash to take a picture of a lit light bulb!) b) WAY too far away to be "lit" by it (See "When should I use a flash?")
What you'll have to do is get a tripod. If you're confident with your camera, change it to the aperture/manual mode and test to see what will work properly. If you are not confident, fiddle around with it anyways! Just keep this in mind, try to get the aperture open as much as you can (A small number, like 2.0, 2.2 means it is open as far as it can be) and set the shutter speed to at least 1/2 a second, probably around 3-5 for a night shot depending on your camera/aperture, iso etc.
It is a very wise idea to use your remote control if you have one. Every little bit of extra shake (Including pressing down on the shutter button!) makes a huge difference for lengthy exposure times. (ed note: using the self timer feature will also minimize this problem)
With some cameras, if you press down on the shutter halfway it will show the approximate image (This only works when the flash is off) that it will capture. Adjust your shutter speed/aperture accordingly if it appears that the image will turn out too bright (UNLIKELY!) or too dark.
If you want some cool shots, crank your aperture up to something high like 7.0 or 8.0 and set the shutter speed to 10 seconds or more, you could end up with a "trace" from satellites, car headlights, airplanes etc.
So try it out! Make sure the flash is OFF and use one of the manual / unprogrammed settings that your camera offers (If you have them!)

The EV system relates to the old ASA number, as well as to the more current ISO system. A change of 1 in an EV number is one-third of a stop- or, for instance, the difference between ISO 100 and ISO 80 or 125.

If you use continuous file numbering on your camera, where the file numbering is NOT reset every time you clear your memory card, it can be annoying when the file numbering is reset for some unknown reason. Some cameras don't provide an option to manually set the counter again.
The solution is to place an image on a memory card (it doesn't matter which) and rename it to the number minus one that you wish the camera to start at again. Depending on your camera, if it creates subfolders on the memory card, you may have to appropriately rename the folders to "fool" the camera into thinking it just took a picture with that file number, forcing it to use the next one.
For this reason, it's a good idea to make sure you keep your memory cards clean if you have more than one, and not switch back and forth because you could confuse the camera and create files with duplicate names.

Problem: My D-SLR images have spots and no amount of lens cleaning has gotten rid of them.
Solution: There are a number of detailed websites explaining this process. If you want a good overview of what to do and what can go wrong, it's suggested you read one or both of these:

From this thread:
Do not forget to have framed prints, matted prints, plain prints.. People are picky and choosy and many will want matted, matted & framed, framed, plain, etc.. My wife tends to take blank (pre-cut) mats with her so she can mat the customer's choice of color for an extra fee.
It helps a great deal to have a variety of sizes from 4x6" to 20x30" even.. Most 4x6" are sold matted to a 5x7" frame size. Doing limited runs can also help.. like say limit a certain picture to 100 8x10" prints and then it is retired (hand signed certificate of authenticity helps also).. but remember to keep track of these as if you sell 101 of them then you can be sued!
A nice way to sell the plain prints is in Crystal Clear Bags which can be purchased for very reasonable prices; they protect your pictures from fingerprints, spills, etc.. They work great for Matted images also.
It is sometimes nice to have a backing material with you as well, like Foam board or something even harder as some people will pay extra and prefer having a ready to hang print.

Why, there's a link that will help you do just that:
»www.photo.net/learn/focustest/
This test was designed more for the Canon 300D/10D because of the acceptable range figures they list, but you can still test your camera for general front/back focus accuracy with this test.

A 50mm lens is considered to be a "normal" lens when used on 35mm camera bodies. "Normal" being that the field of view of a 50mm lens is very close to what we normally see with our own eyes.
A wide angle lens captures more due to its wider field of view. Less than the normal 50mm is considered wide angle. Technically any lens shorter than a normal 50mm lens is wide angle. Wide angle lenses are commonly used in landscape photography to capture more of the scenery. The lower/smaller the number of the focal length the wider the field of view for the lens. Some common examples are: 14mm, 20mm, 28mm, 35mm, etc. These are examples of "prime" or fixed focal length lenses (non variable, non zooming).
A telephoto lens has a lower field of view and brings distant objects closer. Technically any lens longer than a normal 50mm lens is telephoto. Telephoto lenses are commonly used in wildlife and sports photography. The greater/larger the number of the focal length the Some common examples are: 135mm lens, 200mm lens, 300mm lens, 400 mm lens, and 600mm lens. These are examples of "prime" or fixed focal length lenses (non variable, non zooming).
A zoom lens is variable in it's focal length. Zoom lenses cover a range of different focal lengths. The focal lengths can be just wide angle, wide through short telephoto, telephoto only, etc. A 17mm-35mm would be a zoom covering wide angle, a 24mm-120mm would be a zoom that covers wide angle to short telephoto, a 70-200 would cover short to medium telephoto, an 80-400 would cover short telephoto to long telephoto.

There's been a little bit of debate on this in the forum, and I think that some of this is up to personal opinion, but I see one right way to do it (personally).
When you're trying to attain the fastest possible shutter speed, you're doing a guess-and-check method by using Shutter Priority, as you have to manipulate both shutter speed and ISO in order to try to stay at the fastest speed. At that, you'll always be changing shutter speed because of varying light conditions. If you know what the average ambient light is for the venue and you have a stop or two of dynamic range, you can set your camera on manual and just shoot away.
If you use aperture priority, and leave the camera set on the widest aperture, the only variable you need to manipulate is the ISO speed after that. You only then need to keep an eye on your shutter speed, as it will be as fast as possible for the given ISO speed you're at.
Generally, 1/250sec stops motion for basketball. For soccer, I have a hard time stopping the blur of the ball for anything under 1/1000sec.
A flash is generally not the way to go on a P&S if you're going to be shooting spots indoors. The range will not nearly far enough and you will not be able to attain a fast enough shutter speed with ambient light on either of the priority modes (because you should never use a flash at long distances in P mode, it will give you 1/60sec shutter speed and the flash won't work as the primary light source).
It's not exactly easy to shoot indoor sports, even with a dSLR and a fast lens. You're basically at the mercy of the ambient light unless you have remote strobes.

Shoot P, Tv, Av, or M
[ ] is center weighted average, good for portraits and such where you want the subject (center) to be the best exposed, it weighs more exposure decision on the center but then average the rest of the scene as well.
[+] is spot metering, good for macros, wildlife, where you want the exposure to be for the subject only basically and the rest of the scene may or may not be exposed properly
the other mode is evaluative, which is the one you would use for landscapes and such that you want the entire scene exposed properly.
Not the best or most technical explanations, but should give you a basic idea. The following websites will help you even more:
