High and low key lighting
In photography, the term key refers to the overall tone of a photograph. There are two types of keys or tones, low and high. Low key images have very little light, their contrast is high and the lighting hard. High key images on the other hand have a predominance of white or very light tones and tend to look light and airy, the contrast in these images is low and the lighting soft. CONTRAST Contrast is one of the most important concepts in photography; simply put contrast is the difference between the lightest and the darkest areas in a photo.
The greater the difference between the lightest and the darkest areas in a photo, the higher the contrast will be. For example, an image made up of mostly black and white tones is contrasty whereas an image composed mostly of middle gray tones is flat. When we talk about contrast in photography, we refer to both tonal contrast as well as colour contrast.
Tonal contrast is seen in black and white images, and colour contrast is found in colour images. In black and white photography, contrast is created by the difference in subject tones. Subjects portray a number of different tones and when captured in black and white these tones move from white to grey to black. In colour photography tone does not create contrast, but rather contrast is created by colour.
Contrast can be low, high, or normal. A high contrast photograph is made up of white and black areas with little or no grey. High contrast images convey a sense of hardness, power, and strength. A low contrast image is flat, as there is little difference in the density of the tones in the highlight and the shadow areas, all colours and tones in the scene are very similar in appearance. Low contrast images portray softness and gentleness.

Photo Tip: Macro Photography Tools
What is Macro Photography?
"Macro photography" is simply another name for "close-up photography." The closer you can focus on your subject the larger it will appear in the frame, which is the point to macro photography -- to magnify small objects. Some purists insist that the term macro be reserved for images that are at least life-sized in the film -- an object 1" long must record an image 1" long or longer in the film to count as macro to these folks.
I prefer to speak more loosely of macro photography as being anything that uses some sort of technique that yields an image more magnified than would be possible with just an ordinary lens on the camera. For me, macro photography can have relatively small magnification factors -- just as long as there is more magnification than with a conventional lens by itself.
By the way, some people use the term "micro photography" instead of macro photography, but it's the same thing.
What is it good for?
Macro photography lets you fill the frame with small subjects. A picture of a caterpillar taken with a 50 mm lens from 10 feet away is likely to be uninteresting because the subject is a tiny speck in the photo. Make that same caterpillar fill the frame of film, however, and you've got an exciting photograph.
But you can do more than simply enlarge small subjects to fill the frame. You can use enough magnification to overfill the frame with the subject, abstracting out one part of the subject to stand for the whole. With enough magnification, you can make the photo an interesting abstraction where the viewer can't even tell what the original subject was. The possibilities of macro photography are limited only by your imagination.
