Purchasing a Digital Camera
The term "Digital Photography" can be used to cover both still and video photography, when purchasing either of these technologies the same criteria can be used to make sure that you acquire the correct piece of equipment for your needs.
There are many things to consider when buying either a digital camera. The first thing to do is to figure out what your budget is. Camera prices range from a few pounds for low-end models to thousands for the high-end models for professional use. Decide how much money you would like to spend and what the usage of the camera will be. Try to answer questions such as: Are you going to take family photos, shoot landscape photos, travel a lot with the camera, use a lot of flash photography, Speed of aperture for the faster action shot is also important with the stills camera. The same applies for camcorders, are you looking for camcorder to work in bright sunny conditions or darker cloudy conditions such as using on a skiing trip
Once you have decided on the budget and the usage look for potential cameras. If you have decided to look for your camera on the web you may want to make use of a more specific search engine phrase such as" Sony digital camera" or "digital photo printing services", in doing this your results are going to be highly targeted to your particular digital camera needs.
If you create a table you can list the cost and features of each of the different types of camera or camcorder, this will help you to narrow down your search for the correct camera to fit your needs.
The features you should be looking to add to your list should be the following:
New cameras are packed with an ever increasing number of mega pixels. Is more mega pixels better? A quick answer would be yes - but a better answer would be "it really depends". More mega pixels are important if you are going to print photos (especially enlargements) or if you are going to zoom in and crop fine details out of big photos. If you plan to watch your photos on your computer screen and maybe just print a few 4X6 prints every now and then than 2 mega pixels is more than enough (yes... just 2). Most screen resolutions are about 1024X768 so even when viewing the photo in full screen mode you can only view 1024X768 which is less than 1 mega pixels. A 2 mega pixels, 4X6 photo print will have a DPI higher than 300 which is more than enough for a high quality print. If you plan to print photo enlargements then a rule of thumb is to be able to print at least 300DPI resolution. The following is a table for different print sizes and the mega pixels needed for such print quality:
page 4X6 2MP
page 5X7 3MP
page 8X10 7MP
page 11X14 14MP
page 16X20 28MP
page 20X30 54MP
Unless you budget is infinite when you buy a camera with more mega pixels you make a compromise between mega pixels and other features. For example is it better to spend money on more mega pixels or on better lenses? Or maybe on an external flash? It all depends on how you will use your camera. Evaluate your usage and decide what is more important to you.
In some situations it is very useful to have a good zoom capability. For example when you take a portrait photo you want to make sure the object's face fills the photo frame while when you take a group photo you want to make sure everybody is in the photo frame.
Some manufacturers state the camera's zoom figure without specifying if it is optical or digital. Optical zoom works by physically moving the camera's lenses and changing the focal length. By changing the focal length you can make objects appear bigger and fit the full photo frame. Digital zoom works by applying built-in software in the camera to define a portion of the photo which you are interested in. Once chosen the software crops the rest of the photo and enlarges the area you chose to fit the complete photo frame. The downside of this digital process is that the enlarged photo quality is lower than the original photo's. The conclusion is that optical zoom is superior to digital zoom so when you compare different camera's zoom always compare their optical zoom capabilities. You can totally ignore the digital zoom figures.
With ever growing storage capacities digital cameras today can hold hundreds and sometimes thousands of photos on a single media. You can always have a few more in your pocket and changing is very fast. The result is that a digital camera has practically infinite capacity. You can shoot as many photos as you want and at the end of the day just dump them on your computer disk. There is no time lost changing film and there are no photo opportunities lost due to lack of film or reserving film for later.
Advances such as the internet can make us neglect the many different digital photography resources that are currently freely available to us such as the town book shop or town library which can often be an obvious place to obtain guidance about digital camera products, you should certainly make use of these kinds of havens of great digital camera data as suitable digital camera product information may very often be hard to find
