Magnification Explained

I talked about magnification in close-up photography and I said I would explain a bit about its figures and how they relate.
The figures compare the actual size of an object in relation to its size reproduced on film or CCD sensor. This can be seen as a ratio (1:1/2), or in fractions (1/2x or .05x). X = life size.
Life size is where the size of the object is the same as its size portrayed on film. Therefore, 1/2x or 0.5x shows the object to be half life size, so it would appear to be half its actual size when represented on a photograph. The ratio theory (1:2) means the same thing.
So in other words, 1:1 is life size on film. The same as 1x or 1.0x, but 1:2 is half size on film the same as 1/2x or 0.5x, or 2:1 would indicate the object appears twice as large on film.
I hope that has enlightened you.
"Here's another bright idea!"

When creating images of silhouettes, if there is more than one main subject in the scene, consider the "odds" rule, where it is more aesthetically correct to have an odd number of subjects in the frame rather than an even number. Also, because your subjects will be virtually blacked out, it is important to keep them separate. This makes it much easier for the viewer to discern what the subjects are. Also, try not to have too much of the scene blacked out.
