When digital cameras first hit the news, I thought, “Wow! Never to have to buy film again!” This much has remained true, but it took ten years for digital cameras to come up to the quality performed by film cameras. At first, the pixels were too few to enlarge to 3 by 5 much less an 8 by 10 with any quality. Today, pixels are not a problem and every feature adorning the film camera is now available on a digital camera.

I spent many months researching the available models and weighing the cost versus the features until I came up with a digital camera that pleased me. The camera is the Konica Minolta Dimage A200. While some functions are not as sophisticated as their film cousins, the advantages far outweigh its short comings.

In 2004 a decent SLR costs from $900 to $1500. I use an SLR as a comparison because they are the only type camera that shows exactly what the lens sees. The K/M A200 sells for about $600. Its 8 megapixels allows enlargements up to 13 by 19 inches with a sharpness equal to a fine 35mm photo from an SLR. The features I like best are the manual zoom ring (motorized zoom controls are slow and cumbersome), the stabilization chip (which produces sharp images even with slow shutter speeds) and the control over white balance (even custom balances). Another terrific advancement is the flip out rotating LCD viewer. Never again will I be held to an eye level view. With computer enhanced perspective control, all angles are possible.

To be fair, there are a couple of areas that can be improved, but can be lived with.
One is the delay after pressing the button to take the picture while the camera focuses and sets aperture and speed. It’s only a tenth of a second, but you’d better get used to it or you will miss your shot. A remedy is to take a series of pictures and pick the best one. Another is inherent in all digital cameras and that is the artifacts that appear in the image at higher ISO settings. Artifacts are like the grain in fast film that appears like little dots in the picture. If you use the slower ISO settings like 50 or 100 ISO, then the artifacts are practically invisible. If ISO 200, 400, or 800 are needed to get the picture, then additional processing through PureImage or similar software will solve the problem nicely.

A word about the lens is in order. A zoom range of 28mm to 200mm (35mm equivalent) covers just about any focal length an advanced amateur could need. No
other 8MP EVF (electronic view finder) has this wide an angle. The lens is custom made for a digital camera and is very sharp edge to edge. Only a very slight barrel distortion (1%) is visible at the 28mm focal length. Some software can correct this if perfection is demanded. You never have to worry about dust getting on the CCD sensor since the lens is not detachable. If wider or more telephoto effects are needed, there are accessory lenses that will make the wide end 50% wider and the telephoto twice as long. The A200 also has a 4x digital zoom but I recommend that this only be used as a last resort since the number of pixels are halved when you double the zoom. The auto focus works very quickly except in extreme low light.
A manual focus is available with a nice auto 4x enlargement of the center for critical focusing.

No Compact Flash card is included in the package, so I bought a 512 80x CF card for $69.00. The 80x refers to the fact that it unloads to your computer in a jiffy and the 512 Megabytes allows 81 pictures of the extra fine quality JPEG that I always use. The pop up flash lights up subjects at 12 feet away at 100 ISO. For more versatility I bought the Vivitar DF 200 slave flash ($69.00) that works to 50 feet at night.

This camera is a joy to use and has everything I could ever want in the way of features. In the six months I have owned it, I have created dozens of 13 by 19 images for the two Digital Art Shows I have had. Viva la digital generation!

I have been a professional photographer for 36 years and retired for three.

Millions of people have fallen in love with their digital camera; and for good reason. They are compact making them easy to tote along anywhere a person may wander, they are capable of producing images of outstanding quality which can easily be shared online with others anywhere in the world, and with digital storage, they are a space saving wonder. In addition, digital cameras allow users to save the expense of film and developing. But perhaps the greatest attraction of these cameras is the control they provide over the images one creates during the editing process.

Unfortunately, most of those who love digital cameras have also come to know their dark side; their thirst for power. From the first touch of the button to power a digital camera on, setting the focus, shutter speed, zooming, and providing a flash for image capture, to reviewing images taken and editing, these cameras are energy junkies.

The good news is that there are things that can be done to help to make it easier to live with power craving cameras and to curb their appetite. Certainly, having a camera with rechargeable batteries is by far the best option and charging the battery per manufacturer’s guidelines can help sustain optimal functioning. For the people who love their digital camera, there are also steps that can be taken in the way they use it to help reduce the rate of power consumption.

When finished shooting, remove the batteries from the camera if it will not be used for another 2 or 3 weeks. This will prevent a trickling discharge that can occur when left in the camera.

Use the on/off function appropriately. Certainly a digital camera should not be left on for any extended period of time as the energy is wasted. However, if another shot will be taken within a few minutes it is better to leave the camera on as it consumes a great deal of energy to power on/off. If the camera has a sleep mode, it is best to set the timer for that function to the shortest interval in case the user forgets to turn the camera off.

Disable or don’t use features that aren’t needed. Zoom for instance uses a great deal of power. If the same result can easily be achieved by simply moving the subject or stepping closer, do that instead. Use of the flash function is also energy intensive. Flash should be used only when it will be effective. For instance, if lighting is already sufficient or the subject is out of flash range anyway, don’t use the flash function.

When possible use the viewfinder to set up a shot as the LCD screen consumes a great deal of battery power. Use of the LCD screen can improve some shots such as in the case of close-up/macro photography but in most instances use of the viewfinder is sufficient. (Remember, photographers operated without LCD screens for most of the history of photography!)

Use other power sources when appropriate. For instance use an AC adapter when downloading images and use the computer for review and image deletion rather than performing such functions directly on the camera.

Do things manually when feasible. From powering the camera off to focusing; auto anything takes more power.

Some experts indicate that some types of media storage consume more energy as well. For instance, Compact Flash is said to be a more energy conscious form of storage than MicroDrive Media.

Certainly, the many features offered on a digital camera are convenient and desirable. Users merely need to be aware of the tremendous demands placed on the camera battery by these same features. Understanding this allows a digital camera owner to make a choice between ease of use and conservation of the battery.
