This was a fun project! My goal was to create macro images that were based more on color, design, and composition rather that exacting detail. To do this I used a Canon FD manual lens set at 1.8, mounted on a 3 set of Fotodiox Extension tubes equalling 49mm. This was mounted on my Canon EOS M. The camera was mounted on a Macro slide focusing device, then on a tripod. Focus was first achieved with the lens and then fine tuned with the Macro Slide. DOF is extremely narrow when the lens is this close to the subject ( about an inch) ISO was 800 and shutter at 1/50 sec using soft window light as the primary light source. Because the tubes cause 3-4 stops of light loss, seeing the image brightly enough on the live view viewfinder required a shutter speed of .5 seconds for set up. Once I was happy with what I saw, I set the shutter speed to 1/50 to capture the image.
There are many ways to create macro images: extension tubes, macro lenses, close up filters and reversing a lens with an adapter. The most expensive would be a good prime macro, the least a set of these non-coupled aluminum tubes or the lens reversal ring. This is a great rainy day project!
