Camera Buying Tips – Digital Versus Analog
Jul 22, 2010 Uncategorized
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.
Digital and old 35mm film cameras look and are operated almost the same: you look through the viewfinder, frame your shot and push the shutter button. However, the great difference between them lies in the way they capture and process the image. While the 35mm predecessors used the film to capture the image, their digital successors use a charge-couple device (CCD) known as the image sensor. This silicon chip, not larger than a letter key on the keyboard you have in front of your now, contains several grids of photosensitive diodes called pixels and each one of these will store exactly the information contained in one pixel from the picture that will be rendered so nicely on your desktop.
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.
There are two separate devices / media involved in the process: the image sensor, that captures and digitizes the image, and the storage device, similar in functionalities with the hard disk drive on your computer. With traditional 35mm cameras, the film is used both to record and store the image.
The technology behind digital cameras allows users to view the images on the built-in LCD screen (or TV set, if the camera has such an extension). 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.
To wrap it up, if you are to choose between buying a digital camera and an old film one, there are lots of reasons why you should go for the latest technology.

1. Help you find the right community

Unless specifically contracted, all real estate agents in Texas are seller’s representatives, since the seller pays the commission and the selling agent is acting on behalf of the listing broker. Many present themselves as buyer’s agent, but there is no legal relationship unless a specific contract is signed between buyer and the real estate agent. There are many licensed real estate agents in Texas. If you want to purchase a home and wish to use an agent, then you can hire an agent to represent your interests. That makes him a buyer’s agent.
In Texas, second home sales have been increasing over the last few years with more people becoming second homeowners. Over 40 percent of homes sold were second homes. Healthy rise in home prices have contributed to this development in the second home market. With the help of real estate agent, who have a proper knowledge of these kinds of properties, you can relax a bit. Whether you are a buyer or a seller, the professional real estate agent you select, always plays an important role.
