So if you are a newbie to digital photography, then the pointers below on the subject should be just what you are looking for. This post is specially done for newbies; it has everything you need to know about digital photography;
What is digital photography?
Digital photography is simply the use of a digital camera to take photographs. A digital camera is more or less similar to the traditional film camera externally and in basic functionality. If you are serious about digital photography, it’s crucial to know hoe equipment you will use works.
Digital Cameras versus Film Cameras
A film camera is basically composed of a light-proof case, an aperture, lenses, shutter and a roll of film. The case ensures no stray light gets inside the camera. The aperture is simply a hole through which the light with the desired image passes to the film. The lenses allow for the focusing of the desired image onto the film. The shutter controls the duration of focused light exposure on the film while the film captures the image. In addition to the five components mentioned, a film camera needs a viewfinder that enables the photographer to select the region to be photographed.
In comparison, a digital camera is composed of a case, lenses, and an array of photoreceptors. The function of the case in the digital camera is similar to that in a film camera. The lenses in a digital camera help in focusing on the desired image, into the array of photoreceptors in the belly of the camera. A reproduction of the image falling on the photoreceptor array is displayed on a small screen facing the photographer. This screen in a digital camera bears the function of the viewfinder in a film camera.
Choosing the Right Digital Camera
If you are new to digital photography, then you need to be able to choose the right digital camera for your intended use. What follows are some are a few tips.
- Camera Resolution
Digital cameras capture photographs by dividing up the image into tiny identical squares known as pixels. Each pixel functions as a separate and distinct record of the image. As a general rule, the more pixels a photograph has, the higher the amount of detail that the photograph captures. The number of pixels making up a photograph is indicated as the resolution and is composed of two numbers. For example, a photograph whose resolution is 640×480 suggests that the image has 640 pixels along its length and 480 pixels along its width. The total pixel density of such a photograph is thus 0.3 megapixels. A good digital camera should be able to take photos that have a pixel density of at least 2 megapixels. It is possible for you to purchase a digital camera with 2 to 5-megapixel resolution at an affordable price.
Digital cameras store the photographs they take in the form of data files. Data files are saved in the camera’s internal memory. Most digital cameras have an internal memory of 8 megabytes, which is quite small, considering the size of suitable digital photos. To resolve this memory issue you need to purchase an external memory card. Furthermore buying a memory card adapter would allow you to switch memory cards between your smartphone and digital camera. An adapter will enable you to use a micro sd card with your digital camera.
Digital cameras with high magnifying power lenses will offer you much more flexibility when taking photos. A high powered lens would allow you to zoom in on a particular part of a scene, thus avoiding the loss of clarity associated with digital zooming. You should, therefore, go for a digital camera whose lense has a magnifying power of x3 and higher. Furthermore, it is advisable to purchase a digital camera with an auto-focus function. This function allows the camera to automatically adjust its lense, hence letting you take flawless photos.
- Additional features
Finally, you should consider the extra features that your intended digital camera purchase will offer you. Some worthwhile features include red-eye reduction, panorama mode, extended battery life, and picture compression capability.
