Digital Photography Technical Tips
The most relevant question that users have is what kind of camera they should choose. Camera users are categorized into three main categories: amateurs, hobbyists and professionals, and knowing in which category you are can help you identify what features might be important, and what type of camera would suits your needs. Do you want to just take a few pictures of family and friends, capture your vacation memories, or produce shots of nature and landscapes to prepare a portfolio? Also think about how much quality you are ready to trade away for portability, as cameras can range from large and bulky professional quality SLR cameras (Single Lens Reflex) to small ultra-portable cameras, and some of the cameras may not even have a flash. You may be in any one of the above said category and Indian Institute of Photography.com (IIP), online school of Photography guides you in knowing more about camera selection though their Online Photography courses with hands-on experience.
Cameras are typically divided into groups: ultra-compact, compact, prosumer or hobbyist, and digital SLR, and most manufacturers bring out units in several categories to capture more of the market. On each end of the range, the ultra-compacts are made to be the most portable, often fitting into pockets easily and can be used as key chains, while the digital SLR cameras are professional quality tools having the widest range of options, such as external flashes, lenses and tripods (often the largest and most cumbersome to carry). Most units are under the middle two categories, with built-in having a good range of quality, resolution, and options, and the prosumer range includes higher quality and greater control over manual options and accessories.
Buying by only the megapixel rating will mean you, miss out the other features of the camera portability, accessories, a good quality flash, but it is one of the most important considerations. Less than 3 megapixel cameras are much suitable for basic snapshots; the camera will be small and smart enough to take basic ‘I was there’ shots, but the images will not be as clear if you want anything larger than standard 4×6 prints. Between 3 and 5 megapixels, you can have the best range of everyday use and vacation cameras by which you can fill your photo albums with shots from cameras in this range and will be able to make good quality prints at a variety of sizes. From 5 to 7 megapixels, you will find serious, higher range cameras for hobbyists that want to explore photography as an art and the images will take up more hard drive space but will be perfect for taking print out in larger sizes. Choose a camera of 7 megapixels or more if you are a professional and expect to be paid for the work you do, as these cameras are overkill for casual everyday use, but most ideal for professionals who need the highest resolution for larger prints, and more flexible cropping options.
Zooming is one of the important considerations with digital cameras and we have two kinds of zoom: optical zoom and digital zoom. An optical zoom factor relies on the lens itself magnifying the light coming in, so that what is distant appears larger and closer in the resulting image. A digital zoom factor takes the resulting image and magnifies it after the fact. It is well known that an optical zoom factor is much more important than a digital zoom factor which produces better quality results.
