There are many important features to take note as far as digital camera is concern. They are listed below;
1 Resolution: This one plays a vital role in determining how sharp your image will be, and also how much you can crop a photo with it still maintaining the same picture quality. In this light, the picture is going to be almost the same after enlargement or manipulation.
2 Lens: The lens is considered as the eye of digital camera. Here are some very useful features to look in a lens: firstly, you are going to need a lens that is capable of producing a good quality optics that provides sharp images.
So the best way to find out is just to take a test photo or three to actually know if what you are going for is actually good; secondly, the lens needs to have enough light-gathering power to allow you take shots in all light level.
To measure the level of light-gathering capabilities all you need is something known as f-stops; thirdly, you need to actually determine how large or small an image can appear to be from a particular position. That is the magnification power.
A good digital camera’s lens must be able to zoom in and out to either make the image larger or small; finally, you should endeavor to check for a related factor that is to actually know the differences the zoom range and the magnification of the two.
However, what is the main difference between magnification and zoom range? When we talk about magnification we simply mean how large or small an image can appear, while zoom range on the other hand determines the optic range and the relative magnification.
3 Storages: Your digital camera should be equipped with a reasonable amount of removable storage. The more space your camera has for photos, the more pictures you can take. In most digital cameras, you will find compact flash, secure digital or other electronic film as storage facilities.
4 Exposure controls: Most digital cameras are actually made with automatic exposure controls except for the cheaper models. This automatic exposure controls allow your camera to adjust the amount of light that reaches the sensors, based on the lighting conditions of the subject that you are filming.
For instance, if your illumination is probably low, the auto exposure system will enable the wider lens for a certain period of time. If there is a lot of light, the auto exposure system reduce and dim the amount of light that reaches the sensor.
Camera with more exposure controls allows you to specify what type of exposure to actually use. Also, in situations where you want your image to be very sharp, you need choose an exposure option that favors maximum depth of field.
5 Focus controls: In most digital cameras there are options like automated system for sharply focusing your photos. However, some are very flexible than others, and most digital cameras you can manually focus the photo to ensure that the image is very sharp as possible as it can be.
6 Viewfinders: Most digital cameras are designed with four major ways that allow you to preview and compose your image before the exposure proper. The color LCD panel that is usually found right at the back of the camera often shows you the same image that the sensor is capturing.
It is quite difficult to actually view in bright light. Thus, digital cameras also are made with optical viewfinders that allow you to view a non-electronic version of the frame. The more advanced type might even have a second LCD in the camera to shield it from the surrounding light.
7 Other equipment (other features): Lastly, as you go about choosing a digital photography gear, pay keen attention on the accessories such as the add-on lens, tripods, external electronic flash, scanners, printers, and filters. In extreme cases, even the storage media that you are going to use to capture images like CD’s or DVD’s.
