Convenience and customization are the 2 most vital benefits of digital camera technology however this new medium will retain some drawbacks. DIGITAL CAMERAS

Most skilled photographers would admit that photography has return way enough in technology and resolution that it matches film the handfuls of Nikon F5s and Canon EOS1s at the used camera store is one clue. This implies digital photography has reached the standard of most professional’s need for their work. The technology itself has some shortcomings, however:

Resolution of

Consumer-level digital cameras don’t seem to be capable of higher resolutions than what you’d receive from a 35mm camera with an inferior lens.

Color space.

Digital cameras consider a color house or mathematical illustration of all colours. Most cameras use the RGB (Red, Green, and Blue) color house. Different color area definitions exist tho’ that always is superior.


Software and low-resolution sensors work along to degrade the resolution of a picture by blurring pix-elation.

Highlight disaster.

Some digital cameras cannot handle highlights in a picture, leading to bright white streaks.


Forget action or sports photography with a consumer-level digital camera. Stopping action at the exact moment you want are some things of a game and a really overpriced digital SLR (Single-Lens Reflex) is important.

 Wide-angle lenses.

CCDs in digital SLRs are smaller than the quality 35mm film frame. The result’s a magnification of lenses in order that a 35mm becomes a 55mm. wide-angle is troublesome unless you get an exotic (that is, expensive) lens.


Blame it on genetic science or culture, however, digital prints don’t command similar respect as regular prints.

Battery drain

Digital cameras drain batteries quicker than any device. With a little LCD screen, constant auto-focus, and flash, traditional alkaline batteries barely survive a “roll” of thirty-six photos.


Low-end digital cameras presently match Instamatic cameras at worth, however above this client level, a heavy SLR digital camera body prices 2 to three times as much as a standard camera body.

As you’ll see, digital cameras aren’t good. Fortuitously, technology is speedily overcoming these drawbacks. You owe it to yourself to analyze these problems, just in case your dream camera contains a disadvantage.

Capture Delays

By far the largest drawback with consumer-level digital cameras is that the delay. Not like most film cameras, some client digital cameras have a major delay once you depress the shutter (see Figure 2.1). Once you take an image with fixed-focus 35mm film cameras, the image is taken instantly. This isn’t continuously the case with digital cameras. It’s going to take many seconds before the camera will capture the image as a result of the camera should perform the subsequent actions:

  • Autofocus on the subject.
  • Open the shutter when the autofocus is finished to expose the sensor to light.
  • Accumulate enough charge on the sensor.
  • Close the shutter.

At now, the image is captured, however process should occur before the image can seem on the intrinsic camera screen that creates a major (and insanely annoying) delay before you’ll take your next shot.

For this reason, you actually cannot use consumer-level digital cameras for any style of sports photography or photography involving uncontrollable or moving subjects. This, of course, includes kids and pets. If you already own a camera with vital delays, verify however long it truly takes to require a photograph. Chances are high that it takes but 2 seconds, however even this little delay makes action photography not possible.

The camera ought to be an extension of you. It ought to feel as easy as riding a motorcycle. This can be presented solely attainable with digital SLRs that fortuitously are as quick as film SLRs. however, any delays can have an effect on your photography. Your photos won’t be similar. Your goal ought to be to seek out a camera that has no delay, or a minimum of a delay you don’t notice. With no delay, you’ll be ready to use the camera rather more typically.

Sensor Resolution and Crummy Lenses

Lens quality and picture element resolution have an effect on the resolution of a digital camera. Four-, five-, six-, and better megapixel cameras with quality lenses will match the resolution of amateur 35mm images. Digital cameras with fewer pixels (such as a CCD of 2-3.2 megapixels) are fine for snapshots, however simply don’t have the resolution of the film. If the film-like resolution is needed, undoubtedly think about a camera with a chip of 5 or additional megapixels.

Surprisingly additional vital than the CCD is that the lens. In fact, the standard of the lens is thus vital that you simply ought to seriously think about solely the best lens makers for your camera. Firms that turn out the simplest lenses embody the following:

  • Carl Zeiss- Considered the best optics on the planet. (Zeiss com/)
  • Nikon- Exclusively on Nikon cameras. (nikonusa com)
  • Canon- Appear on Canon cameras. canonusa com)
  • Leica- Leica lenses are considered the sharpest among 35mm photographers. (
  • Schneider- An American company that manufactures lenses for Kodak.(Schneider optics com/)

Look for ultra-low dispersion glass, fluorspar (a mineral) glass, panchromatic lenses, and spherical lenses. These technologies that add considerably to the value of a lens will even be found on Instamatic digital cameras, like those from Kodak (Schneider) and Sony (Carl Zeiss).

You might encounter variety of various terms once buying a lens:

  • APO (apochromatic)—These lenses have special coatings that focus on different wavelengths of light (red, green, and blue) more precisely. Nikon calls its APO technology ED, for Extra-Low Dispersion.
  • Fluorite—This type of glass creates lenses that have no distortion whatsoever.
  • Aspherical—These lenses are ground into non-spherical shapes that enable more compact lenses to be manufactured. Spherical lenses also reduce coma, which is common in wide-angle lenses. Coma occurs when rays of light pass through a lens far from its center. The rays do not focus on a point inside the camera, but instead create a cone of light, which looks like a comet tail.
