Digital Camera Tips To Help You See The Light
In my experience as a photographer I came across countless of cameras, both digital and analog. This article is meant to explain the differences between the two technologies and serve as a camera buying guide for the undecided shopper.
So, when the shutter opens to take the shot, each pixel will memorize the intensity of the light that fell on it. Milliseconds later, after the shutter closes, this value is converted to a digital number, and the sequence of the several millions of numbers representing the pixels in the picture is compressed, then stored in the memory of the camera (be that internal or the memory card). When switching the camera in playback mode, this sequence is decompressed, and every single digital value is translated into a pixel on the LCD screen. So, in fractions of a second a lot of calculations are made, and this happens with every photo we take or replay.
Also, once captured, digital photos are already in a format we are all familiar with: you can insert them in Word documents, send them to your friends over your favorite instant messaging client, upload on Facebook, burn on DVD's or simply store them on your hard drive for later usage. This is not the case with the old 35mm-ers, where you had to drive downtown to have the pictures developed, then use a scanner to get a digital version.
The Canon Rebel X1i for starters. Yes, I know it's not out yet, as I write this, but it will be shortly (May 2009). For $900 or less with a kit lens, it's hard to ignore this puppy. Considering it comes with 15MP, and the same image sensor as the $1200 or so Canon 50D, and full 1080P HD video capture, you'd be a fool not to have this on your SLR short list. This best camera repair services and this waterproof digital camera should help with best canon rebel slr.
Even if $900 is too steep for your budget, the nice thing, is that you can still find the older Rebel cameras going back to the XT for sale, with almost as many features, for even less money. Some used, and some new, but you can find the Rebel XT, XTi, and XSi, and XS for as low as $450 brand new.
These series focus on more experienced amateur photographers' needs, who do not make a living off their camera, yet want some more control on the pictures they take. While they are not even close to professional cameras, mid-range gadgets offer a reasonable number of manual controls, and some recent models in this range even come in metal bodies.
This includes fish aquariums where some photographers like to capture images of the captured fish in an aquarium setting. Only take the camera into depths of water that are specified by the manufacturer. Make sure the temperature rating for the camera is safe for any type of conditions you will be shooting the images.
Make sure the camera is rated for being submerged into water and not just protected from rain, sleet or snow. Take the time to learn about the camera. Find out what it can and cannot do before you start using it.
