Digital cameras are a vast improvement over the regular cameras.Electronic sensors are used in digital cameras to store pictures on amemory card. These pictures can be uploaded to a computer by an USBcable. Some digital cameras can record sound and video also. It isimperative to study the different types of digital cameras, theirfeatures and identify our objective before buying a digital camera. Check the following types of digital cameras:Compact digital camera - These are `snapshot` cameras invariably smalland compact in size. They lack sophisticated hardware. Images arestored in JPEG format. Compact digital cameras have a sharp focus and abuilt-in flash.Bridge camera - These cameras form a `bridge` between the compactdigital camera and the DSLR camera. They have small sensors but largezoom ranges. Also they have an LCD electronic screen which can take alive preview of the photo before clicking it. Bridge cameras employeither electronic viewfinders (EVF) or optical viewfinders (OVF). Thequality of these viewfinders is undergoing sea improvement regardingtheir size, resolution, visibility, magnification and refresh rate.Digital single-lens reflex camera - An automatic mirror system is usedwhich displays the exact image. The absence of time lag in the image isa great advantage for taking photos where the subject is constantly onthe move. There is an auto focus system and furthermore, the resolutionis extremely good. The only disadvantage is the absence of a `livepreview` in most DSLR cameras.Digital rangefinder camera - This is a portable camera suitable fortheatre photography, portrait photography, street photography andcandid shots. A rangefinder is a range finding focusing accessoryattached to a digital camera allowing a sharp focus. Wide-angle lensesare more often used in rangefinders. Filters which absorb much light orchange the color of the image can be used in this camera.Check the following main features:Resolution - About 2 - 3 mega pixel resolution is enough for a decentdigital camera. Resolution is a measure of the number of pixels on thesensor that create the picture. It is an important factor for printinga larger image or cropping it. Usually, the higher the resolution,greater the cost.Type of lens - A glass lens gives a better quality picture than aplastic one. Again, a zoom lens adds greater versatility. Close-up mode- Many digital cameras have a special close-up mode which allows one totake close-ups of extremely small objects like jewelry and coins.Manual mode - Modes of different types are there, which enhance thequality of photographs in a particular situation. Portrait, landscapeand close-up are the special exposure modes. Shutter speed and lensopening can be maneuvered in the manual exposure mode. Burst modeallows a number of pictures to be taken in rapid succession. Alsodifferent filters can be used to provide beautiful effects. Extra flashmodes can also enhance the clarity of the picture.ISO - This value normally varies between 100 and 400. A higher valueindicates that more number of pictures can be taken in dim light.Conclusion:After going through the different types of digital cameras and theirfeatures, one should ask oneself about the objective of buying adigital camera. The type of photography, the experience level, weatherconditions, the budget and portability are all factors which need to betaken into account before purchasing a digital camera. A higher megapixel rating means a higher price. If large prints are not thecriteria, then mega pixel rating around 4 should suffice. Lastly, reading reviews of the different digital cameras available forsale might just be the best option before purchasing an actual one.
