The most common thallus liverwort is Marchantia polymorpha. A weedy species, imported all over the world and common in plant nursery pots.

By 'mushrom' do you mean the umbrella like structure. If so there are male and female sex organs located in seperate receptacles. Males are umbrella like and females are umbrella like with only the 'ribs"

Is the change in pattern in the compound eye natural or due to an aspect of capturing and manipulating the image?

Well after looking around at quality and price I ended up buying a Kirk product. If I had more time, mechanical skill, and experience I believe that the Velmex products may work best. Velmex products seem well priced but they do require the addition of a quick release plate to the top and a universa...

Cheap or expensive focus rails

Okay now I am looking at focusing rails to use in the field and studio. There is a wide range of price and for now I would like to save some money. As such are the cheap Manfrotto rails (costing about $90) worthwhile? Are they well constructed enough to allow fine adjustment or does the RRS rails be...

Yes I am already getting the idea that the use of bellows etc. is going to be complicated. Unfortunatley the use of the 105mm macro is not providing the magnification I need so I guess it is time to step up to the next level and see what happens.

Keep the tips coming

Any help and suggestions are appreciated. My intention is to start with one shot. I assume by stacking you mean multiple images layered to provide depth. That is for the future. As for optics I have a Nikon D200 Lenses: Nikon 105mm 2.8 VR/AF macro Nikon Micro 55mm 2.8 Nikkor 24mm 2.8 I am willing to...

Beginner's Setup

I would like to start doing some macro photography at home. My thought on a set up is a Nikon D200 with a PB-6 bellow and a lens on the front. Since I would like to phtograph vertically (lichens and mosses) I was thinking of mounting the setup on a copy stand that will allow me to make rough adjustm...
