How to Solve Digital Photography Image Problem
Many people have unrealistic expectations of digital photography. They may believe that digital photographs are 'perfect' in terms of colour and detail. In fact, many problems can occur -- some of them are an inherent part of the digital domain, while others can be caused by incorrect settings on the camera. Here are a few simple way to solve image problem.
1.Reducing Noise
Any part of a digital image that was not present in the original scene is referred to as 'noise'. It may appear as specks in the photograph, washed out areas of white, or blotchy patches where there should be an even gradation of shade.
There are several things you can do to keep noise to a minimum. It is most noticeable in shots with extended exposure times or high ISO settings. ISO settings are related to film 'speed' -- high-speed film can capture images at very short exposure times. This is ideal for action shots such as athletic events. However, High ISO setting produce more noise than low ISO settings.
Similarly, long exposure times also introduce excess noise. Long exposure settings can be used to take pictures in low light conditions such as dimly lit interiors. Keeping ISO settings low and exposure times relatively short will minimize noise as you take photographs.
2.Colour balance control
Digital cameras can be adjusted for colour balance but they need to have a reference point. This is what the white balance control does -- using white as a reference point, the digital camera can, in theory, accurately reproduce all of the other colours.
Most cameras can be set to automatically adjust the white balance. This setting is usually the most appropriate but for tricky light situations the automatic setting may be turned off to allow the photographer to manually adjust the camera. This can also be used for artistic effect -- a white balance set to an extreme can produce weird, unearthly colours.
If you have the opportunity to re-shoot a scene which has been improperly exposed, by all means go ahead and try to improve the image. However, if the scene cannot be re-created, save the image and try to work on it with software.
3.Choose the best Quality lense
If you are using lense and image quality is important to you, be sure to get good-quality glass lenses .A bad lens is going to give you bad images. That is why it is essential to choose a digital camera with the best quality lens you can afford.
Get good-quality glass lenses and keep them well maintained. Dirt and dust on lenses can cause distortion and noise in the final image, so keep them as clean as possible without excessive handling. A soft brush and a blower should be all that is needed if the lenses are kept covered when not in use.
4.Use Imaging Software
Professional imaging software such as Photoshop can be used to correct colour irregularities, white balance, lens distortion, incorrect exposure, and blurring.
Digital photographs, after all, are computer data which can be manipulated down to the bit level, so it is always possible to change the minutest detail of any image. Software can automate many of these corrective functions, and manual manipulation is also possible to improve any digital image.
