Camera Lens

Lens is the most important part of your digital camera; it is the window towards the outside world. A small scratch or spot on the lens will destroy the whole picture. Hence, care should be taken to keep it clean but not by touching with the fingers directly. If there is any dust, first try to blow it up, if it is still there wipe it with a soft lens cleaning tissue or you can use a lens brush or lens blower. You can even find lens cleaners specifically meant for digital camera. Do not forget to cover the lens while the digital camera is not in use.

Delicate Parts of the Camera

Memory card is one of the most delicate components of your digital camera. You may find CompactFlash, SD or MMC cards in your camera. They …

The differences between the two are very similar to the differences between traditional hard shell luggage and soft shell luggage. Hard shell camera are made from injection molded hard plastic, while soft camera are usually made from high denier nylon. You can also get leather camera, but these are quickly losing favor in response to the versatility, stain resistance and strength of nylon.

Some photographers favor hard shell cases because they’re virtually indestructible. If you’re traveling around the globe and have to check your camera bag, you’ll probably feel better using a hard shell case. If you’re boating down the Nile River and there’s a danger of your camera falling overboard, a good hard shell camera will float, which can save you thousands of dollars. Who wants to see their camera and gear at the bottom of the river?

Auto focus

A high-quality auto focus system is essential to take sharp pictures. The EOS 70d is installed with the latest Dual Pixel AF technology to make it easier to shot fast-moving objects. This DSLR auto focus system includes a total of 19 focal points. This increases the cameras capabilities to focus on the subject. Also, the 70d comes with a bigger 20.2MP sensor to help improve the contrast and clarity of the picture quality.

Video

A further aspect of the Dual Pixel AF technology is the ability to increase the quality of video recordings. Earlier models of the DSLR cameras had issues with loss of focus as objects moved around. This problem is solved with the 70d due to its ability to swiftly auto focus as the camera is moved from subject to subject. The camera supports standard HD …

A dome camera is simply a small board camera that is mounted on the inside of a dome-shaped housing. These cameras are usually mounted on ceilings or under overhangs above doorways and porches. Most dome cameras have a plastic cover for inside use and others have a metal cover for outdoors.

The dome camera is the camera of choice in most circumstances because they are generally less expensive and easiest to install. Also the indoor dome camera in a plastic cover makes it very hard to tell where the camera is pointed, so one camera can effectively deter theft outside of its normal field of view. You can’t duck below the cameras field of view if you don’t know which way the camera is pointing. The mere existence of the dome camera tends to ward off criminals and thieves. The …

The first thing we budding photographers had to learn was a sequence of f-stops (aperture sizes) – f2.8, f4, f5.6, f8, f11, f16, etc – and that each was twice/half the size of its neighbour, with f2.8 being the largest, and f16 the smallest. Similarly, the shutter speeds were 30th, 60th, 125th, and 250th (on my camera anyway), and each was twice/half the speed of its neighbour. The final bit of information came with the film; a slip of paper that said something like this (for 100 ASA film):

1/125th and f/16 on a sunny day with distinct shadows
1/125th and f/11 on a slightly overcast day with soft shadows
1/125th and f/8 on an overcast day with shadows barely visible
1/125th and f/5.6 on a heavily overcast day with no shadows
1/125th and f/4 on in open shade or …

The exposure is controlled by 3 (three) adjustments we make in the camera: shutter speed, aperture and sensitivity. Shutter speed and aperture ultimately control how much light comes into the camera (we can compare this to a water tap – how much you open the valve and for how long will dictate the amount of water that will flow)… and how much light is needed for a certain exposure is determined by the sensitivity of the medium used (today it has been expressed as ISO numbers – and as ASA not so long ago).

In the digital cameras world today, we can find ISO ranges from as low as 50 up to 204,800, being the normal range placed somewhere between 200 and 1600. These numbers have some qualities associated with them: it sets the amount of light needed for …
