Digital camera
Digital cameras have the balance of quality, features, and price that appeals to users looking for a fast and convenient way to get images into their PC. You can spend a lot more — or a lot less — for one than the $100 to $3000 (or even more) these cost, but you won’t like the quality at the low end or the prices at the high end. Digital cameras have limited storage space. If you’re traveling, you’ll have to spend every night figuring out which pictures are worth preserving on a laptop computer’s hard drive. Digital cameras are becoming more and more popular and truly multipurpose. In addition to everything else, you can use your camera as a portable “scanner” to capture text from hardcopy documents, books, newspapers, as well as from banners, posters and other media.
Digital Camera Basics has basically been “offline” for a good while in the sense that I haven’t updated the site in a year or more. I’m not gone. Digital cameras contain “microlenses” above each photosite to enhance their light-gathering ability. These lenses are analogous to funnels which direct photons into the photosite where the photons would have otherwise been unused. Digital camera technology is directly related to and evolved from the same technology that recorded television images. In 1951, the first video tape recorder (VTR) captured live images from television cameras by converting the information into electrical impulses (digital) and saving the information onto magnetic tape.
Imagine you have a webcam setup in the corner of a room. Now take your Wi-Fi/3G-enabled camcorder at some other place from another angle either in the room using WiFi (ad-hoc or not) or anywhere in the city using Wi-Fi/3G-enabled networks. Imagine, Levoy says, if the camera could analyze highly-rated pictures of a subject in an online gallery before snapping the shutter for another portrait of the same subject. The camera could then offer advice (or just automatically decide) on the settings that will best replicate the same skin tone or shading.
Videos are recorded in the AVI format, and not in the fancy new AVCHD codec. This means that videos files will be large and take up more space on your card, but can be easily viewed and edited with contemporary software. Video after the jump.
