i was reading another thread about a blind man taking photos (go read it if you have time, interesting debate about unique human perception). Anyway, a particular post from a DPC member made me think...
There are some macro shots (especially obvious) that are nothing interesting EXCEPT the fact that they give a very close-up view of a particular thing. It may not provide any special angle of view, and is bluntyly nothing new to most people. However, there's the thing I noticed - they get accepted very well by viewers. I'm not complaining, I'm just trying to tell everyone that if we are able to shoot a photo of something that people normally cannot see, no matter how un-interesting the subject may be, I think it's gonna sell.
Now, anyone mastered the method of shooting micro-photography? I havent seen any of them in here yet, or have I missed some galleries? I'm gonna shoot some sperm photos and sell it to clinics. LOL

I took this photo with a toy microscope but it didn`t go down to well.
Can`t think why :)

| It would sell if you had better equipments to shoot it. With a toy telescope??? I find the photo interesting. I have never seen a head lice this close. Thanks for the photo. |

| micro shots?? Does anyone know anything about cameras which can be fitted onto dissecting microscopes?? |

| does those microscope-photo-taking-camera digital photos can be considered DPC material? We have those in the office, they use it for shooting photos of microscopic cracks and defect of our discrete products. Hmm.... |

| I was just asking my father about this, as he works in a microbiology lab and needs such photos in his presentations to the NIH and at world conferences. They have one, but haven't used it in some time. I'll go check it out... |

I've done quite a bit of digital photography using both metallurgical microscopes and stereo microscopes. I use my Nikon 995, mated to the eyepiece. There are some tricks I use to get good images, however there is nothing really difficult about the method. The results can be technically very good, but are usually uninteresting unless the viewer has some knowledge of the subject. Here are some images I've recently done, resized and posted to my portfolio. They don't look quite as good as the full resolution images, but...
Memory Die Surface & Solder Bumps
Analog Die & Substrate
Analog Die Surface
Organic Acid Crystals
I'd sure appreciated comments on these. I know the compositions are very dry & technical, but the images were taken purely as technical documentation, no artistic intent.
edit: damn typos!

These are quite good illustrative photographs.. good work. They are clear, and the colors are vibrant. I am not familiar with your subject matter, but it seems to get the point across to me :)

| now, what's the best way to mount a larger lens'ed camera to a microscope with minimum vingetting. with telescopes you can use large eyepiece but with most microscopes the lower bits are changed around |

Hi Michael,
Of course the very best way is to use a DSLR and a "trinocular" microscope head with an adapter for the SLR mount. If your microscopes don't have trinocular heads, and you don't have a DSLR, then like me you're stuck with eyepiece photography.
For eyepiece photography alot depends on the eyepiece as well as the camera. Many low-buck microscopes have very small eyepiece glass, and work poorly even with my 995. Higher end microscopes are really necessary to deliver the image quality you will want anyway.
The best way to mate the camera to the eyepiece is with an adapter ring made specifically for the camera/eyepiece combination. The objective (pardon the pun) is to hold the camera precisely aligned and centered on the eyepiece, and be able to adjust the distance of the lens to the eyepiece without bumping the lens on the eyepiece & damaging the lens.
We're talking a custom-machined piece here; I'm not aware of anything being sold on the open market for this purpose.
With the camera mounted, you will find that only parts of the zoom range give the desired result.
Another issue with some cameras is that the front element moves as part of the zoom. These cameras are not as well suited to eyepiece photography, as use of an adapter ring is not possible. It's still possible to use them in hand-held mode though, with some care.
Ive faced this problem shooting with a digicam we have in our R&D labs. I found that I get much better results with my 995, even though our other camera is 4Mpx as opposed to my 3.14 Mpx.
Nikon caught on to this very quickly, BTW. They have had an adapter to mate the coolpix 995 to a trinocular head, and they sell the camera and adapter as part of their better microscopes. I don't own the adapter, since our Nikon scope does not have a trinocular head.
I still do most of my micro-photography hand-held to the eyepiece. This works OK for me, but when I get some time I will machine adapters for the two scopes I use. I can get away with hand-held 'cause I've got the necessary lighting. You really need a very good built-in light source on a high-power scope. Our Nikon Optiphot has a 50W halogen illuminator, and there are times when it's really not enough.

If this isn't what you guys are talking about than sorry, i'm not fully awake yet. But here is a link to an awesome portfolio of photos that were taken through a microscope.
Microscope Art
Enjoy.

Heather,
This is a great link, Thanks! Shows the artistic possibilities of micorscopic photography. Wish I had the time to experiment more.

Wow this is an intresting Thread. What timing my Happy Little White Blood Cell brings to light. Well if I can answer any questions let me know.
