With film in the Mamiya MSX500, I attempted the same technique with a feather (the feather's former owner had no further use for it having encountered Mango). The Mamiya can't get as close in as the Pentacon, so this used an extender tube: Obviously the feather is translucent, so I attempted to get the feather with sunlight shining through it. Problem here was too much light for the camera's top speed of 1/500s. So, an assistant held a sheet of white paper behind the feather so the sunlight passed through the paper before going through the feather. As you can see, at these magnifications and light levels, you start to run into DOF problems. Will keep working on it! Regards - John

Interesting studies, John. DOF can be a real bugger with extension tubes...but can produce some fascinating effects!

Forgot to mention - the feather is approx 1/4 inch (0.5cm) at its widest part.

That small!! I was imagining something like a seagull's wing feather, or at least one from a pigeon, not one from a frush's froat!!
With the size in mind, that's quite something of an achievement John. Well done.
