Photographers who use the P, A, S and M shooting modes can control two key image parameters, which are blocked when the auto and scene pre-set modes are used: sensitivity and colour adjustments. These adjustments can influence the appearance of images quite dramatically.
Most cameras provide two basic focusing options: automatic, which is controlled by the camera and lens; and manual, where adjustments are made by the photographer. Which you use is a matter of personal preference, although many photographers rely on the autofocusing (AF) system and use manual focusing to fine-tune focus in tricky situations. A capable AF system should lock onto subjects quickly and accurately when the shutter button is pressed halfway down.

In this article, Photo Review technical editor Margaret Brown offers practical tips and advice on how to use both monitor and viewfinder to frame and evaluate the photos you intend to capture. Margaret uses a compact system camera for illustration in this article, and most of the tips and advice apply also to DSLR cameras.
Different cameras provide different levels of control, ranging from very basic to highly sophisticated. More sophisticated cameras have external mode dials, although the functions that can be accessed via these dials can vary between simple and highly automated and professional standard.

Smart autofocusing can mean the difference between a usable image and a missed opportunity that will be discarded. Focusing also influences depth of field: the range of distance within a scene that appears acceptably sharp.
Don’t put your camera away once the sun goes down; there’s plenty of magic to record after dark, whether you’re in a bustling city or an isolated landscape. And you don’t require elaborate equipment if you decide to hand-hold your camera.
