In photography, a camera is an optical instrument that captures light or other celestial radiation and converts it into electrical signals. Some cameras work digitally, others chemically. Still others are microelectronic devices that use mechanical lenses to image a surface within a range of wavelengths—as with an electron microscope or endoscope—using principles similar to those of the human eye.
Tips to buy the best Camera
The level of quality that a camera is able to achieve is measured by how many pixels it has.A lower pixel number might not always mean that the camera cost cheaper. There are features which you might want a higher pixel camera for, i.e. portrait or bird photography where you want the smallest details to be clearly visible.
The quality of the lens that the camera has determines how sharp, detailed and colorful the image will be. Lenses are priced according to their quality, size and brand and they can range from very cheap to extremely expensive depending on what you specifically need from it as well as your budget!
What function you need the camera to have will depend on what you are going to use it. A camera that is used to take pictures of landscapes or architecture and others where you might want to change the settings manually is ideal and will cost more than a typical point and shoot camera. A digital SLR camera is different from a compact camera which is like a regular digital camera but with a smaller sensor size and usually less features.
There will be a difference in storage capacities in most cameras. For example, a camera that has high quality lenses and is used to take pictures of landscapes or architecture will have more storage to be able to take plenty of pictures. A compact camera that you want to take along with you might not last long on a memory card but it won’t cost you as much either. It all depends on how much you need the camera to store and how often you want to use it.
