Casual Photographers: First, you may be a casual or occasional photographer. That would include beginners as well. The casual photographer will probably take pictures at birthday parties, family gatherings, vacations, or other occasional events. The pictures that are taken will probably be shared online and usually won't be enlarged to print sizes larger than 8 X 10.
If you fall into that category, then a Basic Compact Camera would be a good fit for you. The ease of use of and reasonable pricing are the main appeal of compact cameras.
Compact digital cameras are the least expensive type of camera to buy and the image quality they produce is usually very good. You can navigate to http://www.angekis.com/ptz-camera-system/ to know more about HD PTZ camera.
There are also scene modes included with compact cameras that allow you to choose a setting to match the scene you are shooting. Some of the common scene modes are the beach, fireworks, portrait, and landscape modes among others. However, those are all optional settings that you can use if you choose to do so.
There are Advanced, or "Bridge" type compact cameras available that can work for those individuals. These types of compact cameras have semi-automatic and manual controls that are not available on a basic compact camera. The most important settings that can be controlled with a Bridge camera are the shutter speed, the lens aperture (lens opening size) and the ISO (the camera sensitivity to light).
Advanced Photographers: If you find that you have a great interest in photography and want to take your skills to another level, then a Digital SLR camera can work for you. Also, if you have been takings pictures for a while or feel limited using a compact camera, a Digital SLR camera might be the best fit for you.
Every Digital SLR camera will have the same basic features as a compact camera including the option to shoot using the fully automatic mode. However, when you use a Digital SLR camera, you will have full manual control over every camera setting. That will include the exposure settings as well as focusing.
The quality of the images taken using a Digital SLR type camera is better than that of the previously mentioned cameras. That is because Digital SLR cameras have larger image sensors and better camera lenses. The larger image sensor size can produce images that can be enlarged to greater than 16 X 20 print sizes without much if any loss in quality.
