Focusing Your Camera Center AF (Auto Focus) Most digital cameras use contrast detection to auto focus (AF). Usually, the focus point is a small rectangle in the middle of the viewfinder frame (Center AF), though many digital cameras now also offer additional AF points (Multi-Point AF). Center AF If you look in the LCD monitor of your digital camera, there will usually be a rectangle at the center of the screen, commonly called the AF Frame. When your digital camera is set to Center AF

that something else happens to fall under one of the AF points and is also more contrasty than your main subject. In these instances, switch AF mode to Center AF, point the AF Frame on your subject and half-press the shutter release button to lock focus on your main subject, then reframe, if necessary, before fully pressing the shutter release button to take the shot.

If you don't have a tripod, hold the camera with both hands and keep it steady by leaning and bracing yourself against a wall, tree or pole, the roof of a car, anything. You can also hold your camera in both hands and brace your elbows against your body. Another way to help minimize camera shake is to use the viewfinder instead of the LCD to compose shots. Bracing the camera against your face helps steady it. Digital cameras with long telephoto lenses are more prone to cam

Zoom Optical Zoom v. Digital Zoom Most digital cameras come with a zoom lens, which allows you to adjust the length of the lens to either move closer to the object (a long lens) or to move farther away from the object (a short lens). Digital cameras usually come with two types of zoom on them. The first is the optical zoom which is identical to that found on traditional cameras. When using optical zoom, you can get closer to a particular object without any sacrifice in image quality.

Even if you can't get as close, use photo editing software to crop instead of using the digital zoom. You can't crop a tremendous amount, but you can get closer while retaining quality. This is the same image shown above as the optical zoom example. Top of Page swheeler Page 6 of 34 IMT – Cholla Training Center

Flash off There are occasions when your camera thinks the flash is needed, but in fact it isn't. You probably have a "Flash Off" (or similar wording) setting on your camera. Here are a few examples of when to use it: • When you are too far away from your subject for the flash to be effective. • When the flash would create annoying reflections from mirrors and other shiny surfaces. • At sunset or in other low-light situations where you'd like a foreground subject to be silhoue

Program Auto (P), your night pictures always come out too dark. They are simply underexposed. But, why is that -- if your camera's shutter speed ranges from, say 10 sec. to 1/2,000 sec.? Go back to your camera's User's Manual and look a bit more carefully. Are all the shutter speeds available in Auto or P mode? Ah-ha, many digital cameras (we're talking consumer models here) do not make the whole shutter speed range available in A and P mode! Perhaps the slowest shutter speed available i

Manual Mode – Overexposed Switching to Manual mode allows me to access the slowest shutter speed available on this camera, 3 sec. while keeping the aperture at F2.8 (the largest aperture available). The effect is immediately better, but it does seem a bit too bright, giving an almost a daylight effect. Now it is just a matter of adjusting the shutter speed and/or aperture to obtain the desired exposure. I choose to close down the aperture so as to increase the depth of field als

Size of Picture Click here for content source web site. Pixel Count One of the main ways that manufacturers categorize their digital cameras is in terms of pixel count. This is the number of individual pixels that go into making each image. Today this number varies between 1 million (1 Megapixel) to around 14 million (14 Megapixels). A million pixels is abbreviated to MP, so a 1MP camera has 1 million pixels and a 3MP camera has 3 million pixels. Currently most popular consumer digi

“good/normal” compression setting will compress an image at a ratio of 16:1. A “better/fine” setting will compress an image at a ratio of 8:1. A “best/superfine” setting will compress an image at a ratio of 4:1. The higher the compression ratio is, the more images may be fit onto the memory card. Using these generalized numbers, you can see that having a “good/normal” compression setting allows you fit many more images on a memory card. However, when an image is compressed, detail is los

Ten Tips for Great Pictures + One Click here for content source 1. Look your subject in the eye Direct eye contact can be as engaging in a picture as it is in real life. When taking a picture of someone, hold the camera at the person's eye level to unleash the power of those magnetic gazes and mesmerizing smiles. For children, that means stooping to their level. And your subject need not always stare at the camera. All by itself that eye level angle will create a personal
