Now And Then: Photography And The Canon Powershot A590is

By Don Bethune

In 1826, the photograph was taken, and an amazing hobby was born. As much an art as a science, it has changed the way we remember events and report the news. That first picture was taken with a simple sliding box camera and printed on a mixture of silver and chalk that reacted with the light. That was a long time ago, and the advances in film, lenses, and lighting have been great. Cameras were created in many different forms, with different uses and styles. This allowed not only professionals to have their tools, but average users to capture the moments they wanted to preserve.

The earliest cameras were bulky and required the use of what is known as "plates." Made of glass, these plates were smeared with mixtures of salt and chemicals that could capture images when exposed to light. Importantly, these early cameras led to the creation of the camera "shutter," a mechanism which would control the timing of the plates exposure to light, as well as the amount of light permitted to hit the exposure mixture.

The first use of film in photography came in the early 1900s and led to the mass-marketing of cameras later in the century. 35mm film came in a roll and could easily be loaded into a camera for quick and repetitive snapshots. As manufacturing processes improved and competition amongst makers flourished, cameras became cheaper and increasingly compact.

Users praised the creation of the instant camera (remembered most often as a Polaroid) which bypassed the darkroom and created prints on the spot. Film reached its limits, however, and was soon overtaken by the digital camera. With a color display, and free from the tyranny of fragile film, these cameras have made amazing pictures simple and easy. They convert an image into a series of data, called pixels, representing the tiny dots of color you see on your computer screen to make a picture. This data is much easier to store than film, so users can take more pictures.

The software built into cameras now also takes out much of the guesswork. The aim and focus for you. They control the shutter-speed and help you frame the shot. Special modes help you get the photo just right, whether it is a sporting event or a close up of a flower. The detail you can now get in both tight shots and panoramic vistas, day or night, is astonishing. Plus, you can do anything with these photos, from putting them online and sending them to friends, to retouching them on your computer and printing them out.

One of the most popular cameras today is the Canon Powershot A590IS. It is as easy to use as any other point-and-click camera, but it also has all the necessary manual settings to please the skilled photographer. Plus, the 4x optical zoom brings you closer than other cameras, with a clarity that a simple digital zoom can never create.

You canat mess up shots any more with a camera that has 19 shooting modes and 7 scene selections. Plus, you will have no more blurry shots. It comes with an image stabilizer. Most photos taken by amateurs are portraits, and the face detection software keeps the focus on the face, rather than an object in the background or foreground. With the Canon Powershot A590IS youall take pictures people couldnat have dreamed of thirty years ago.

If you get one, be sure to look at the Canon Powershot A590IS manual. Sure, itas simple to use, but you can learn a lot of tips to create even better pictures. Another nice feature comes when you need a new Canon Powershot A590IS battery. You donat need something special or expensive: just two AA batteries.
