Today people are switching from film cameras to digital models. The reasons are obvious ease with which objects are framed and shot, the images are stored, recorded and displayed. To make matters worse, you can download from the comfort of your home and pictures of the press.
However, if you buy one for the first time, chances are you've lost, literally, to revise the specifications and features offered by many brands out there in the market. Go to the mega pixels, or go by the manufacturers or the price range or …. Possible classifications, so there are many. The following guide is published with the intent of helping to achieve a practical model of FeaturesWeight choice.Various
This factor strongly depends on the use of digital camera. Want to wear one in your pocket or purse, go for the lightness. No doubt they are convenient, but have small buttons, controls and buttons that can make management a bit 'difficult. The largest weighs more and have more features too.Resolution
The cameras are classified as mega-pixel resolution. Reduces the range of cameras and to help solve the beginner, intermediate and advanced groups of them. The range is 0.1 mega pixels to 18 mega pixels and some even more. The key to choosing the right pixel camera depends on how close you want to achieve target.2 mega pixels and less sharp images and details sufficient to print 8x10s and small. Quality copies are not very high, but sufficient enough to be published in emails and websites. These cameras are inexpensive.2 to 6 mega-pixel Given that the resolution continues to grow in this range, the picture quality even better. You can get sharper images at all in escalating price.Eg Canon PowerShot S3, Fuji FinePix V10, etc.

http://www.reviewgist.com/digital-camera-reviews?resolution=6.37-to-8.32ZoomOptical-lente enlarge the image is magnified by the lens 3x, 4x, 10x and more, but keep in mind that a very long zoom is subject to camera shake. Use a tripod to cover this problem. 3x optical zoom means you can make a subject appear three times closer. Optical zoom produces images of better quality. You can not get too close to the object, but then a photo editing software can help to reduce the image. Gives better results than using the digital zoom.
Digital zoom is a simulation of an optical zoom, which expands only the central part of the image. The aim is not used in this case. The effect of digital zoom is provided by the internal software. The result is often a blurred image and digitized. You can use both zoom effects on both cameras offer such features.Lens
A bad lens can ruin everything that controls the resolution and additional image processing. So before buying one to evaluate the final image on a computer based on these criteria:
check the overall objective of focus and sharpness, though the corners are sharp as the center
verification of combustion, ie, colored circles and reflections when shooting toward the light source
objective control attachments offer, you can add wide-angle or telephoto lens, accessories to extend the focal length
whether electronic or manual control, zoom, zoom speed manual offers more flexibilityMemory
Unlike film cameras to digital cameras store images in memory. Thus, whenever the memory is full, you can download them and the camera is ready to shoot again. The memory is of two main types: integrated and removable. The lower end cameras have built-in memory. Removable memory cards have the advantage of upgrading the memory, particularly useful when taking pictures in a lot trip.Flash Types
It all started with the photographers lighting a powder keg full tray to illuminate a scene. Digital cameras today come with built in auto flash drive combined with a sophisticated light metering system, exposure control. They are so convenient and easy to use that often do not realize.
Digital cameras are specified by a tracking number that gives substantially the power of flash. The greater the number of guidelines, a greater range of flash utility. With the changes in the speed sensor and / or focal length, the monitoring of changes in number. So the producers, instead of specifying the maximum capacity of flash, with the assumption that the flash is fully charged and the lens opening is wide open.Some common arrangements:
Auto mode is well known! Cameras with the way first red-eye reduction fires a short burst to close the subject's iris, then the main flash, and, finally, the picture is taken.
Fill flash mode to fill the shadows.
Flash off mode, in order to capture the natural light.
The night scene mode sets the foreground subject, without underexposure of the background. For maximum flexibility in choosing a camera flash with an external clamp.
Some models are equipped with only the external flash.
Some varieties have both external and built-in flash units.
Some compact digital cameras equipped with every type flash units.Focus
Most digital cameras have a combination of different ways focus. In automatic mode, when you press the shutter release him and a half, the focus is locked. E 'approach was also confirmed by a color change indicator.
Auto Focus is achieved in different ways. The most common of these is the only way to approach the area. The focus is on the central portion of the screen. In fire mode on the spot, the focus is in the center of the screen. The resumption of slow moving objects can be used in continuous mode auto focus. Be aware of the enormous energy consumption in this Focus mode.Manual-This feature allows you to focus manually by a scene that may or may not be the center of the screen. Select the area that is focused with an indicator of focus of some activation of a cursor button to make the approaches and macro shooting. Some models have a fire ring for manual focus, turn to when the subject is in focus focus.Fixed-This function can be used to their advantage when there are pre-set distance between the camera and the object.
The various combinations of rates of interest are:
Autofocus and manual focus
Autofocus and fixed focus
Auto, Manual and focusCamera fixed type
Standard automatic point and shoot cameras, the models are available with the basic features of those with the controls and advanced options and excellent macro capability. The flexibility with which these cameras can be used as in situations where it is difficult to frame the picture or shot from the level of life makes these models in high demand. This is an ideal interpreter of silence for the shooting in places where a loud shutter clicks is not appropriate.SLR/Professional- more interesting features such as interchangeable lenses, flashes, sophisticated controls and other accessories, these models are designed specifically for photographers and professionals. For example. Nikon D40, Nikon D40x, etc
2FProfessional http://www.reviewgist.com/digital-camera-reviews?cameraType=SLR%
Compact-The features are mild, but small enough to fit in your pocket before you go to the party. These models are relatively more expensive than standard cameras appear similar size. For example. Canon PowerShot SD800, Kodak EasyShare V550 etc
Compact http://www.reviewgist.com/digital-camera-reviews?cameraType=CompactUltra With technology improving at a steady pace the size of the room is getting smaller. Homes size of a credit card, slightly thicker than take pictures incredible. No compromise on battery characteristics, such as liquid crystal displays (as small as 2 inches), an optical viewfinder, a good resolution (some with 7 mega pixels) and good too. For example. Casio Exilim EX-S500, Samsung NV3, etc.
http://www.reviewgist.com/digital-camera-reviews?cameraType=Ultra-CompactBatteryThere two types: those rechargeable batteries. From digital cameras to energy very quickly, especially if you use an LCD screen, it is better to invest in rechargeable batteries. Some digital cameras come with AC adapters, if your does not have one, purchase separately.
Some batteries are:
NiMH batteries are the most sought after today. They are rechargeable, long-lasting, and are available in various designs and compact, with no memory problems.
Alkaline batteries are not rechargeable and do not last long.
Lithium ion batteries are small and recharges quickly.
NiCad if not loaded correctly can have a memory leak.
AC Adapters allow you to keep shooting long after the batteries are dead! Price
Fortunately, you have to spend huge amounts of owning one. Low Range
Even a couple of hundred dollars can get a good camera with video capability and Nice zoom. And they are sub-par models of the past. For example. Nikon Coolpix S5, Canon PowerShot G7, etc.
http://www.reviewgist.com/digital-camera-reviews?Price=0.01-to-237.49Mid-range
Much more features are added, more megapixels, more powerful lenses are available in this range of digital cameras. For example. Nikon D80, Nikon D200, etc.
http://www.reviewgist.com/digital-camera-reviews?Price=237.49-to-599.84High range
These ranges of cameras are mostly professionals capable of representing the image and produce exceptional photos excellent. For example. Nikon D2Xs, Canon EOS-1D Mark III Body only, etc.
