Most cameras which render digital photographs combine several aspects of light filters in its use. The most common elements that can be controlled by the photographer would be:
- ISO which determines the aperture of exposure
- Brightness which control the exposure of the subject with reference to backlights
- White balance for the contrast
- Shutter speed for time of exposure
- Focus which determines the focal distance for a clear image of the subject and controls the level of blur
All these aspects can be found in any digital camera, however, in a DSLR, some of these options including zooming can be done manually.
Most digital cameras come in relatively cheap with respect to the extremely powerful cameras that are usually seen with professional photographers. However with a budget like 500 dollars, one can easily come up with a DSLR among the beginner’s range. These cameras are best for hobby photographing and can even hold up to panoramic views in the right settings.
Photography takes on an incredibly diverse subject field where the entirety of the job description depends on the experience of the photographer. The subject in focus should not be too outlandish with respect to background, and yet should not vanish in it either. The blends should be made perfect in the photograph’s raw form itself and not through any digital texturing software which can make the photograph look artificial. Most of the mathematics involved can now be done automatically by a DSLR using a variety of sensors.
