Left Hand Brace
Since I do all of my macro hand held (the critters I go after are normally too active for a tripod to be practical) I’m always looking for a way to brace the camera. First because I don’t crop and composition is important and keeping the camera steady helps me to place the critter where I want it in the frame, but also because the flash can’t freeze all the motion in the scene. No matter how short the flash duration is it will never be short enough to give you sharp details if there is a lot of movement. I’m convinced that a lot of the image softness that people blame on diffraction is really nothing more than a form of “macro motion blur”.
One trick that I’ve been using to keep everything steady I’m going to call the “Left Hand Brace” method, and here’s how it works: I’ll slowly take hold of the flower that the subject is on by pinching the stem between my left index finger and thumb. I’ll then brace the lens on that same hand and focus the scene by sliding the lens. Since the flower and the lens are all on the same support (my left hand) when one of them moves they both move so it’s easy to keep everything perfectly “still” and I have a lot of control ever where I put the area of sharp focus. Another benefit of holding onto the flower’s stem is that I can slowly rotate the flower and change the angle to get different compositions.
It doesn’t always work, and it helps if the critter is hungrier than it is scared of me, but when I am successful at holding onto the flower I can get some very unique images that are razor sharp even when shooting at high magnification and Fstops. The image included with this tutorial is a recent example of what I can do with the Left Hand Brace method.
