The Wonderful World of Macro.
Ah, Macro photography. " The technically correct definition would be to take an image at a 1:1 ratio but, in general usage, the term has come to mean any close-up photography." That's about it in a nutshell. However! There are some pointers and standard tips that will help anyone out.
Get CLOSE! While many cameras zoom very well, as the magnification of the image goes up, so does the amount of shake visible, sometimes leading to blurry images.
Get Uncomfortable! Sometimes being a photographer and trying to get the shot can make one feel something like being a contortionist, but you'll know it was worth it when you get the shot! Oftentimes the most interesting things are found in the most unlikely of places, and it's up to YOU to find them! Search everywhere, and you'll find LOTS of tiny, interesting things to take photos of. :)
A Couple More Hints.....
When shooting, another great rule is to keep things simple. If there were more than one tiny flower in the photo to the right, it would diminish the beauty and solitude of the single. Though, the one in the background, blurred with the shallow DoF, lets you know that there are more in the universe. The opposite of the simplistic would be the repetition found in some photos. This is a fairly handy tool as well, when used appropriately.
The Brightest part of the photo should be the spot where you want the eyes of the observer drawn, In the below, titled Wet Grass, you see that the brightest spot is right at the center of the water drop- it draws the eye, then lets it linger on the detail in the blade of grass it is gathered on. In the flower of the clover to the right, it is obvious where the eyes is drawn.
And When It's All Said And Done....
When all things have been considered, macro photography isn't so much about being in the right place at the right time, it's looking all around one for the inspiration that others overlook. There are microcosms of awesome going on everywhere. From a dragonfly sitting on a leaf, to the mushroom that someone else would accidentally step on- the beauty of Nature abounds. Flowers are always great practice, especially for DoF, but digging deeper, finding the things that make you smile. I find that the things which I find interesting and take photos of, others enjoy as well.
