dandelion bee

This small bee was visiting a dandelion in my yard. Though not especially colorful, it is a good subject for practice as there is much detail to explore... I have not checked for wing lice... Pentax *ist DS, Pentax 50mm f4.0 macro lens, f11,1.5s, 36 photos, with ~ 90 mm of extension from the camera ...

Opto-isolators...

It is a very good idea to use the opto-isolators to trigger the camera. I currently connect two of the digital IO pins on my microcontroller via 10k ohm resistors to the focus, shutter trigger and share the controller ground with the camera. I see the advantage of the optical isolation to avoid an u...

Now I get it...

I'm a bit slow as I had not followed the link to the dorsal photos. They are also very nice. My own rolly-polly photos were taken early in my explore of stacking. I was desparate for a subject having photographed all the dried up spider kill in my basement. It was March in Illinois and the soil had ...

Good photos!

Very nice.

I am no expert on woodlouse but are these ventral views?

Here is a good quick reference for bug descriptve terms.

Raising the bar

Wow... I am seriously impressed. Especially by the last photo that shows the texture of the pollin grains. Very impressive indeed. My wife who won't look at my bug photos was impressed by the shot of the pollin on on the bee's leg. Very nicely done! How did you imobilize your subject? I usually free...

One more test...

I'll add a test with the objective distance ~ 160mm on the extension tubes. Thanks for the sketch. The distance (measured with a meter stick) of the testing that I described in my previous post is about 215mm. The addtional test will have to wait as I have work commitments that will keep my nose to ...

Tube Lens concerns...

Hmmmmmm.... I will have to digest these comments. I'll shoot a comparison with and without the 200mm.

If nothing else I have a compact telephoto lens that is sharper than my 140-300mm zoom for taking photos of the wrens in my wren house.

200 mm as tube lens

It was suggested (wisely I think) that my 10X Olympus SPLAN 0.30/170 lens would benefit from a tube lens. After I figured out what a tube lens is, I purchased a 200 mm telephoto to place between the objective and my camera. As I have a Pentax DLSR body, I chose an inexpensive fixed focal length lens...

Questions I missed

In regards to the dissimilarity to the very elegant SteamPunk rig... Yes, I agree we are polar opposites. I lack the craftsmanship to create such a piece of art. And with an abundant supply of old wooden paint paddles and shish-kabob skewers, well the rest is history... I got the idea for using the ...

I pulled out my archived "masters" and counted 28 frames in the wasp photo. Photographed with the LED lighting pictured with 2 second exposures, ISO 400, the 50mm macro lens f-stop was between F8 and F11. The effective aperture with all the extension tubes is quit a bit less. I did many experiments ...

BugEZ rig

Yardman, I have posted illustrations (see the equipment forum, BugEZ rig) of some of my rig that illustrate the "fork". It is just a shish-kabob stick with a slit that is a bit smaller than the shaft of the toothpick. I wedge the toothpick in the notch and rely on compression and friction to keep it...

BugEZ home equipment

I have made stacked shots for about 2 years and developed my own rig for this. Unfortunately I just connected with this forum so my "evolution" was independent. While my rig is not as substantial as some of the arrangements I have seen on this forum, I have gotten some reasonable results. Some bad p...

Bug Ethics, and lighting

Yardman, 1. I started killing bugs with Black Flag spray... Bad idea... Very messy and the bugs looked oiled. I now use ther freezer. 15 minutes in the deep freeze in the basement, or 20-25 in the side by side in the kitchen. If you are "serious" about this hobby, you may wish to get a killing jar. ...
