Digital Photography: In Focus

Imagine taking pictures and printing those moments later. Unleash the power of digital photography and this is what happens. All that are required for taking a digital photograph is a digital camera, a PC, a USB connection to the computer, a printer and a photo-editing program. The first step in taking a digital photograph is to familiarize yourself with the digital camera. Now, do not get frightened! Here is how you can deal with it.

All about a Digi Cam

Pixel
This is short for picture element, the smallest piece of a digital image. A pixel is also referred to as a single point in a graphic image. These elements are the building blocks of your picture, similar to floor tiles or the squares in a mosaic. Put millions of these tiny squares together and you have a digital picture. In fact, "megapixel" is a simple way of saying one million pixels.

Resolution
This refers to the number of pixels in an image. The more the pixels in a digital photograph, the more detail the digital photograph can contain and better the image quality. It also refers to the sharpness and clarity of a digital photograph. It is measured in Mega pixels. One Mega pixel is equal to one million pixels. A low resolution refers to less than 1 mega-pixel, high-resolution refers to greater than 1 mega-pixel and advanced high resolution is 4 mega-pixels or more. In Digital Photography the resolution of the camera is the most necessary feature to produce first class photographs.

Auto Focus
A good choice for general picture taking is auto mode. This setting, allows your digital camera to automatically set the exposure, the focus, and the flash. With auto mode, you may override the automatic options of the flash and choose to turn the flash off, use fill flash, or red eye reduction.

Digital Zoom
This crops your image and magnifies the result of the cropping. This magnification process is called interpolation. Sacrificing image quality to capture the moment is more important than not getting the picture at all.

Optical Zoom
This physically tends to magnify the subject. A motor controls the lens movement. When you press the switch to W or T, the subject is either magnified or reduced in size. They are wide-angle (reduce) and telephoto (magnify) respectively. This allows you to view the subject before taking the picture.

Memory
It denotes the number of images stored in the camera.

What camera gear of mine will "transfer" to the Canon 50d?

I currently have a Canon xt and i am wanting to upgrade the body possibly to the Canon 50d. What i have for the xt is a Digi power battery grip, telephoto lens and the packaged lens. Will the lens that came with the xt (18-55mm) work on the 50d? I would imagine that it would fit all eos cameras but it is a bit more Professional of a camera than the xt. So basically if the lenses will work ill just sell the xt body (and prob the battery grip since im sure it wont work)

All your lenses will be fine, the 50D takes all EF and EF-S lenses. The battery grip will not work, you will need to buy a Canon BG-E2 or BG-E2N grip (or similar third party grip).

The 50D is a great upgrade, I went to the 40D from the XT and it was a smart move.
