Left Clicking
I recently bought a wemacro rail which works well with my Sony camera but was a bit inconvenient with my digital microscope. The digital microscope software takes a picture when a screen button is clicked. I found that this tended to cause vibration, better if I could stand away from the table . Als...

Apple tree lichen
1:1 macro using Medical Nikkor 200mm f5,6 on Sony A7. I had no idea of the species, just thought it made an interesting picture. Looking at an 'idiot's guide' subsequently I think yellow one is Cushion Xanthoria. The other grayish green one may be Flavoparmelia but not so easy to identify. Correctio...

Lee, I apologize for the crazy Imperial (English) system of measurements... metric is much better! The apology is a bit rich coming from an American considering that this is a UNC thread, basically an American standard. The UTS is currently controlled by ASME/ANSI in the United States The English s...

Stereo Macro introduction
This is reposted from Talk Photography and I am sure many here will have in depth knowledge of the process but I hope that some of you find it interesting. I have played with stereo on and off for some years and built various twin camera and sliding rigs but only very recently started trying macro s...

You might find it worth scrolling through this long thread on Talk Photography. Lots of weird and wonderful examples there of home made light guides and diffusers.

Re: Motorized bellows
On this first try and from my limited experience I couldn't judge whether better or worse but it was noticeably easier to stage and light as there were no moving parts (rails or lenses) near the subject. It seems to me that this improvement is due to reversing the bellows, not to focusing by rear e...

I'm very taken by this idea and since my very basic rig was set up I had a quick play. http://www.photomacrography.net/forum/userpix/5566_A7_201709_1.jpg I reversed the bellows completely so the rails came back under the camera and because the weight distribution was all wrong I added a makeshift re...

Rik, thank you. I had seen the link in another post which is what prompted me to raise the subject here, particularly with flower/butterfly applications in mind. The advice you both have given is appreciated. I'm a Sony user so clever focusing programs are not available. Depending on the lens I may ...

Focus stacking by focus ring
I understand that this is preferred over using a rail but how do you determine the steps to get regular spacing? Most focus rings have a non linear (logarithmic?) scale and focus by wire lenses follow some complex rule in which focus change depends on speed of focus ring adjustment as well as absolu...

An ML-7 :smt007 ? Well spotted Sir! Dates from 1957 I think You could easily do some stitching with the cross-slide. With the chuck as well, if the aligning tool could twist the frames about! Hmm - possibly engage the lead screw, put the camera on fast continuous and do some automatic focus stackin...
