Macro an a budget :: Claresholm Alberta Photographer

Some times it's nice to just stop and photograph the roses... or in my case, these beautiful yellow flowers my wife has grown outside our home. The issue is that they are very small.

When it come to photographing small objects you a few choices. you can buy a Macro lens or you can pick up some extension tubes. The macro lens route will give you a better image quality in the end but will also take a bigger chunk out of your bank account. If you're like me and you don't do a lot of Macro work then a good option might be the tubes.

What the tubes do is decrease the minimum focusing distance of your lens. Each lens has a limit to how close it can be to a subject before it can't focus on it any more. the For the images above I used my 50mm f/1.8 and all three extension tubes. The closest I could get without the tubes was about 14 inches away. With the tubes the flowers were almost touching the front of the lens (1 or 2 inches away). You don't have to use a 50mm like mine. A lot of people use a longer lens so they can be a little farther away so their lens/camera will not cast a shadow on their subject. I tried it with my 70-200mm f/2.8 but liked the look I got from my 50mm.

A few things you have to know before you start using extension tubes are as follows:

  1. Use a tripod! When you're really close the slightest movement is magnified just as much as your subject is
  2. Your depth of field is a lot shallower then normal so close down you aperture more to get more depth of "focus" in your image.
It is a amazing what you will see when you start shoot the world around you from this perspective.
