Snail eggs
These were taken with a 10X objective using oblique brightfield illumination.
These would move slowly, but occasionally they would all remain still enough to quickly take a stack of images.

Dan, Yes, naturally there was some touch-up required because of the problem you mention. But not nearly as much as I had feared would be the case. As far as equipment is concerned the most difficult part is getting a wide-angle lens that will allow smooth and continuous focus from over 1:1 out to &q...

Radiolaria
The fossil skeletons of radiolarians are very three dimensional, making them a tough subject to photograph with a microscope. Stacking with Helicon Focus allows for some nice looks at these structures. Canon 350D above an Olympus BHS microscope. Olympus 20X S Plan Apo objective with DIC illumination...

Urania riphaeus (Sunset Moth) wing scales
This is from a stack of 19 images. It was taken at 20X (magnification on sensor) using a Canon 40D camera and a Nikon 20/0.40 CF M Plan microscope objective... both mounted onto a Nikon bellows.

Macro/Landscapes
Here are a couple of "macro/landscapes" made using Helicon Focus. These are from the Quinault Rain Forest in Washington State. The light was very "flat" this day (I would have preferred a brighter overcast), but it was extremely calm which is absolutely essential. You really can'...

J.D., The 24-105L is a very good lens, but not really a great choice for this kind of magnification. Since you already have extension tubes, a better (but relatively inexpensive) choice would be a reverse mounted enlarging lens or 50mm normal lens (f1.8 or slower). You will also need a way to either...

Centipede head
These are images of fairly small centipedes that were found in moss samples. In both cases looking at the ventral side. The upper image was taken with an Olympus 4/0.16 S Plan Apo, using darkfield illumination. The stack consisted of 19 images. The lower image gives a good look at one of the articul...
