This post is dedicated to my friend Abhishek who claims that photography is his passion and I feel he doesn’t understand the P of photography. I have advised him to go through a professional training for photography and I wish he finds some time from his busy schedule. When I thought of learning photography the first need was to understand a camera.
A digital camera is a camera that takes videos or still photographs, or both, digitally by recording images via an electronic image sensor.
Basic Features
1. Battery: Some digital cameras use standard alkaline batteries. Others come with rechargeable batteries and an AC power cord for recharging. To extend battery life, use the electronic LCD screen sparingly.
2. Camera Dock/Docking Station:A small, convenient desktop device you place your camera onto. It will automatically download photos from the camera to your computer, and charge the camera’s battery at the same time.
3. Digital Zoom:A digital zoom is software inside the camera that crops (selects part of) a photo and enlarges that portion. The digital zoom is handy, although it does reduce the resolution (sharpness) of your photo.
4. Display/LCD Screen:The screen on the back of the camera. The display lets you see the image you’re about to take, and view the photo after you’ve taken.
5. Image Resolution and Mega Pixels: The resolution of your digital camera determines what you can do with your photos, such as post them online or make prints and enlargements. Resolution is made up of building blocks called pixels. A million pixels together are called a megapixel. Today’s digital cameras have resolutions ranging from less than 3 megapixels to over 8 megapixels. The more megapixels, the more picture detail is captured, resulting in larger-size prints that look sharper (depending on the type of lens and zoom setting you’re using).
6. Downloading: Downloading is transferring photos from the camera to a computer or printer. It is usually done with a USB cable connected to the camera, or by removing your memory card and inserting it into your printer or memory card reader. Using a docking station or a printer dock is another convenient way to download
7. Flash: Most digital cameras are equipped with a built-in flash that is activated in dim lighting. Full-featured cameras have extra flash modes, such as red-eye reduction and night-portrait settings
8. Image Stabilizer: Some cameras come with an image stabilizing feature. It automatically eliminates any camera shake – the slight jiggling motion that can result as you hold the camera – helping ensure a crisp, sharp photo.
9. Lens: Basic point-and-shoot digital cameras have a fixed-focus lens. Most other models have an optical zoom, a digital zoom or both. An optical zoom lens actually moves outward toward the subject to take sharp close-up photos. However, a digital zoom simply enlarges the center portion of the subject to fill the frame, producing a photo with less detail.
10. Memory: Digital memory is the “film” of digital cameras. “Internal memory” is built into the camera and cannot be removed. Removable media, or external memory, consists of a memory card that can be removed from the camera so you can download later.
11. Memory card: This is the media on which the camera stores the images that it shoots. It may be filled with pictures, downloaded, and refilled thousands of times, which is one of their major advantages over standard photo film
12. Optical View Finder: This is a small “window” generally located at the top of the camera. Optical viewfinders are handy for two reasons:LCD screens are hard to see in bright light, so composing your shot is hard.Using the optical viewfinder (and turning off the LCD screen) will make your batteries last considerably longer.
13. Optical Zoom: This is the same kind of zoom lens found in high-end film cameras. An optical zoom lens actually moves in and out to get wide-angle, telephoto and macro (close-up) shots. Unlike a digital zoom, an optical zoom will not reduce the resolution of your photos.
14. Resolution: Resolution refers to the concentration of pixels or megapixels used to make up a photo. Cameras with higher resolution can take sharper photos. Resolution is expressed by the number of horizontal pixels multiplied by the number of vertical pixels in a square inch. For example, the most basic cameras have a resolution of 640 x 480 pixels per square inch (about 0.3 megapixels). Some advanced models can go up to 8 megapixels and beyond! A camera up to 4 MP will produce a sharp, full-frame print of 8 x 10. If you want to crop (select), then enlarge a portion of the image with no loss in quality, 5 MP and up is your best choice.
