While using the digital camera, a lot of individual tasks get united to produce a collective of a successful photograph and present it in its best. A well-calculated, properly balanced and artistically superb photograph is just only half the road crossed. The rest of the road that still remains to be crossed is the quality of the prints and enlargements of the final image; and these depends very severely upon none other than the camera settings for file size and resolution. Thus this area of the digital camera image quality and the image size requires a deal of analysis and understanding to make the complete effort perfect. This discussion is only a minor effort to get down this complicated subject down in simple language and legible to the readers as well as the users of the digital camera.
Analysis by research reveals that most digital cameras store photographs in a compressed format called JPEG (or jpg). A few digital cameras even have the option of selecting other formats such as TIFF that are uncompressed formats. For digital image quality and image size, the digital cameras offer different compression levels like fine, normal and basic. Where fine mode produces the smallest amount of compression and enhanced image quality when it requires to be enlarged. For printing purposes conventionally only the least compression setting possible are used.
Image resolution is the number of pixels contained in a digital image. The majority of digital cameras have menus for selecting a combination of resolution and quality suitable for a particular situation. Resolution relates to the size your image appears on a computer monitor rather then the physical dimensions an image will print. For perfect printing a high resolution and quality setting is quite useful. The rule remains that the higher the quality, the larger the image files. A properly exposed photograph produces a fine quality image print. Most digital cameras have provisions for changing the image resolution. For example, some of the commercially used values are two mega pixel digital cameras are 1600 x 1200, 1280 x 960, 1024 x 768 and 640 x 480.
The digital image size usually refers to largest uncompressed image the camera is able to store. Cameras usually offer an assortment of other file sizes. This enables the users to select the size for photographing a particular image at a particular situation depending upon the discretion of the photographer. Basically, the greater the number of pixels in the picture, the larger becomes the image file. Again a very well accepted fact remains that an exceedingly compressed image file can never be uncompressed back to its original echelon of quality, thus in the compression process some of the intricacies of the image gets lost. This is the relationship between image compression and quality.
With all the details of the above discussed lines regarding the digital camera image quality and image sizes, any novice person or interested can gain sufficient knowledge to appreciate the features of this fine device, the digital camera and also make ample use of it in producing good photographs!
