Whoring my Photography...

I'm into lichens this week because all the bugs are frozen, and I'm just geeky enough to be out freezing my, um, parts off, photographing quasi-invisible little doohickeys. Actually they're very interesting. So I decided to share my interest with the online community at large via a gallery hosting site. This can become as huge a project as I want to make it, especially if I start running tests and try to key these specimens to their respective species. I've only just started this gallery and already I have quite a bit of time in it. Being stuck on 24k dial-up certainly doesn't help matters much. I don't expect everyone to be interested in this sort of thing, but honestly, am I going to be the only one who ever looks at this? Take a look and let me know what you think: gallery

At the time of this posting, I only have five images up, but I've commented individually on each one, and at least made an attempt at an ID. I took all these today, by the way, and it was damn cold. I am on vacation, and I would like to head out to the strip pits to get some shots of some Cladonia and Cladina lichens that I know are there. Is there even a geekier way to spend your vacation?

In any event, feel free to enjoy what I've put up already🙂

At 5x magnification the entire photograph represents only a 5x7mm piece of the real world. At 3x it's 12x8mm. All of these are somewhere around there. Much smaller than a dime:Q

nice. with that depth of field you probably have a ton of shots you dismissed... digital is a good thing, eh?

At these kinds of magnifications depth of field is brutal. At 5x it's only about a millimeter deep even at obscenely large f-numbers. Trial-and-error is the word of the day here.
 

Look nice, with nice use of side lighting to enhance textures.

You might want to purchase a heavy-duty tripod with a fluid head for better control & more depth of field. For every f-stop increase you affectively increase the depth of field by about 70%, therefore going from f:11 to f:22 you should get 70% more depth of field and 190% if uses f:32.

Another thing that you might want to look into is making a reflectors out of aluminium foil & cardboard on a wire to mount on the tripod. Or, purchase a lens mount macro flash for fill flash to bring out the shadow details in your subject.

Ps. Your image is slightly blurry therefore you might want to increase the shutter speed to 1/250 sec to compensate for hand shake blur.

Good luck!

A tripod won't get me in the places I need to be. I have one, but never use it for this kind of thing.

I have a macro flash.

At 5x magnification f/11 becomes f/66. I've already lost a lot of sharpness at this point. Going any higher is counterproductive.

The blurriness is from some sort of funky compression scheme Pbase uses.

Thanks for the suggestions.
