1. Use your right hand to grip the right hand end of the camera. Your forefinger should sit lightly above the shutter release, your other three fingers curling around the front of the camera. Your right thumb grips onto the back of the camera. Most cameras these days have some sort of grip and even impressions for where fingers should go so this should feel natural. Use a strong grip with your right hand but don’t grip it so tightly that you end up shaking the camera. .
2. The positioning of your left hand will depend upon your camera but in in general it should support the weight of the camera and will either sit underneath the camera or under/around a lens if you have a DSLR.
3. If you’re shooting using the view finder to line up your shot you’ll have the camera nice and close into your body which will add extra stability but if you’re using the LCD make sure you don’t hold your camera too far away from you. Tuck your elbows into your sides and lean the camera out a little from your face (around 30cm). Alternatively use the viewfinder if it’s not too small or difficult to see through (a problem on many point and shoots these days).
With film cameras you were always wondering if you have enough exposures left on the roll and if you had another roll of film. With the digital camera, you can take lots of pictures and then immediately edit them to remove the ones you don't want. If you didn't get the shot you want, you can probably try again. This is especially useful taking group shots - someone almost always has their eyes closed. The two things that determine the number of photos you can take before downloading are the resolution (quality) and the amount of memory in your camera. You can buy memory cards that will increase the number of photos your camera can hold.
The concept of digitizing images on scanners, and the concept of digitizing video signals, predate the concept of making still pictures by digitizing signals from an array of discrete sensor elements. Eugene F. Lally of the Jet Propulsion Laboratory published the first description of how to produce still photos in a digital domain using a mosaic photosensor. The purpose was to provide onboard navigation information to astronauts during missions to planets. The mosaic array periodically recorded still photos of star and planet locations during transit and when approaching a planet provided additional stadiametric information for orbiting and landing guidance. The concept included camera design elements foreshadowing the first digital camera.
Texas Instruments engineer Will is Adcock designed a filmless camera and applied for a patent in 1972, but it is not known whether it was ever built. The first recorded attempt at building a digital camera was in 1975 by Steven Sasson, an engineer at Eastman Kodak. It used the then-new solid-state CCD image sensor chips developed by Fairchild Semiconductor in 1973. The camera weighed 8 pounds (3.6 kg), recorded black and white images to a cassette tape, had a resolution of 0.01 megapixels (10,000 pixels), and took 23 seconds to capture its first image in December 1975. The prototype camera was a technical exercise, not intended for production.
A digital camera (or digicam for short) is a camera that takes video or still photographs, or both, digitally by recording images via an electronic image sensor.
Many compact digital still cameras can record sound and moving video as well as still photographs. In the Western market, digital cameras outsell their 35 mm film counterparts.
Digital cameras can do things film cameras cannot: displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device, recording video with sound, and deleting images to free storage space.
Digital cameras are incorporated into many devices ranging from PDAs and mobile phones (called camera phones) to vehicles. The Hubble Space Telescope and other astronomical devices are essentially specialised digital cameras.
