A very odd looking amoeba!

I haven't seen anything quite like it before. While scanning the slide quickly at low mag I thought it was an unusual ciliate of some type, but when I looked more closely it appeared to be an amoeba. Any ID thoughts welcomed. My guess for now is that it might be a testate amoeba with no test. http:/...

Mosquito Larva

It's always interesting for me to see the internal muscles and structures that show up when crossed polarizers are used. I loaded an eyedropper with some water from a nearly dried up birdbath and it was full of mosquito and midge larvae. The shot below is an overall of one of the specimens on the sl...

Rik... I thought that would catch your attention. I know that in college bio labs Drosophila are regularly anesthetized by several methods, and one of the most common is CO 2 . I have a CO 2 "duster" that is normally used to blow dust off of optics and equipment. Well, it will anesthesize Tabanus as...

Ken... the lens "section" is all 65mm MP-E. (In fact it extends a little more... 5:1. The picture shows it at 4:1). There are no additional tubes or anyting in there. It gets quite long when focused to the maximum magnification. It comes with the tripod collar shown in the picture.

Rik... I checked and the number of frames used were 28, 15, and 8 respectively. I used that focus rail/focus rack set up I showed you a while back, with a flat platform out front (at C) and a "doped up" horsefly. (Actually I assembled it with these images in mind). I have put a picture of it here fo...

Thanks Mike. With the arrival of HFv4 I did another brief test comparison with AutoMontage, Helicon, and CombineZ. There will always be "artifacts" and errors that require clean-up with all of the programs, especially with subjects as 3-dimensional as these flies. So if you make use of this type of ...

New 4X and a new fly. (Wild lookin' one too!)

Helloooo.... anyone out there? What happened to all our photomicrographers? A whole weekwith no posts. Well here's a new one. Picked up a good 4X and found a very interesting fly on my little trip into the Olympic Mtns. This fly is a little smaller than a "housefly" and has very nice color pattern. ...

They were made from "stacks" using Helicon Focus 4. I photographed them in the shade on a very clear day at about 6000 feet elevation, and the light was all from the blue sky. (I mention the conditions because with film they would have turned out completely blue unless I had used a very large amount...

Horsefly

Just got back from a few days in the Olympic Mtns where it seems like I was constantly surrounded by a frenzied swarm of these horseflies. So I took the opportunity to photograph these "head-shots". http://www.krebsmicro.com/forumpix/HF3.jpg http://www.krebsmicro.com/forumpix/HF2.jpg http://www.kreb...

Lake Martin, Louisiana

A little hesitant about posting this spot for two reasons... I've only been there once (2005), and this spring (2006) saw many birds arrive but leave early. But it is a wonderful location, it's on my favorites list, and I can't wait to get back again. The bird rookery is the big attraction, but ther...
