The resolution decides ultimate future of hard copy of a photograph being taken, whether a digital camera or a conventional camera. A print from a high-resolution photograph challenges anything produced from a chemical film camera. However a low-resolution image print of a photograph is quite appalling with fine details and restrained color transitions absent resulting from too few pixels. Thus resolution can spoil an entire effort to freeze a memorable moment. Thus it is so vital. As a general rule a minimum of 200 pixels are required for each linear inch of a print. However, some printers get better results with 300 pixels per-inch of resolution.

The above discussion has brought into light a lot of relevant information regarding resolution and its application in digital camera and photography. Also in concluding lines it can only be stated for digital camera ... resolution is real soul!

Considering a general acceptable fact, depth of field decreases, as image gets nearer to camera. This means that as focal point reaches closer to lens, achievable scope of depth of field ebbs. On other side, if image is far enough distant from camera, and for digital cameras, this must not be very far, depth of field approaches out to infinity. Another important point to be noted is that depth of field is proportional to lens opening.

Having discussed above important aspects of light and depth of field of a digital camera, it is clear that minute details make such great subjects whose knowledge becomes equally important for making appropriate use of fantastic device, digital camera! And digital camera, light and depth of field comes out to be such important factors that can make all difference if a photographer remains oblivious about this knowledge. A small factor thus can meal a big divergence!
