Re: photomesography

I can't see any missing term. If it's not macro or micro (in scale or by approach) then it's simply "photography". And even if you did find a word, (say "close-up" for example), then the next question will always be "what's that then?". As Rik said, you'll need more words...

Re: photomesography

I just call the whole lot "photo macro micro" in terms of activity and consider all of it simply "photography" when capturing images. The terms, photo, macro and micro are too vague for any useful delineation these days (IMO). The overlap of magnification ranges and equipment used in each genre has ...

Re: Polarisation: a brief dalliance with glycine

They look feathery and dreamy. Lovely results, maybe I should get some to play with too. Oh -- another a9 user! Thanks. There are a few cheaply available amino acids. The pure chemicals are sold as health and bodybuilding supplements. All worth a go, but I didn't want to get sucked too far down thi...

Polarisation: a brief dalliance with glycine

I saw some polarised shots of glycine in a Facebook group and liked the convincing "landscape look". So I ordered some glycine to see if I could make some landscapes of my own for use in surreal composites (arty farty stuff). I simply made a weak solution and dabbed out a few dots on a coverslip, so...

Re: Diatom arrangement at 20x

Lovely shots and arrangements! It is frustrating to lose diffraction colours at higher N.A. I experimented with taking hi-res and low-res images of the same FoV, then use the lo-res one to provide "hue" and the hires for "luminance" (changing layer blend type in HSL mode instead of RGB). There can b...

Lovely. And a bonus points for the longest chemical name I've yet seen in the context of polarised crystal shots :D

Re: Why aren't flies blinded by the sun?

Thank you for your comments everyone, and Rik for the definitive answer (definitive enough to satisfy my curiosity, anyway). I learnt a lot more about fly eyes in general over the course of this too. All good stuff. Cheers.

Why aren't flies blinded by the sun?

I saw one sit completely still in a penny-sized spot of bright sunlight for 10 minutes before it flew off. It prompted this thought that I've never considered before. Their compound eyes have no eyelids or irises (right?) but do have lenses. So even if bright, visible light is no issue, surely there...

Re: Would you recommend a tripod or monopod for macro in the field?

Thanks, Mark, that's interesting. I think the key element is the shaft and slider sticking out at the front. Acts as linear guide for capturing a hand stack. I think it must need to be rested somewhere though, so not *quite* what I'm looking for. But that idea is filed away - certainly could be usef...

Re: Would you recommend a tripod or monopod for macro in the field?

Actually, a device like that would be rather simple to make. Just mount a Stackshot on a pistol grip :-k Yes - I knocked-up something similar on a thin aluminium plate (with a WeMacro rail). Just a bodge to try it. Not quite what I'm after. I want the tactile physical connection between my finger a...

Re: Would you recommend a tripod or monopod for macro in the field?

Hopefully, speculation isn't too far off-topic... I'd like something like one of those gunstock camera holders, but with a modification. Squeezing the (long-travel) trigger slides the camera and lens smoothly forward on the mount while triggering the camera at regular intervals (preferably per unit ...

Re: Darkfield Adapter for Whole Slide Imaging

Beta version is coming - light from both sides (separate dimmers) & sample can be rotated. Oh my! That could be so good for diatom arranging and easily adapted to my setup(s). I think I have some suitable parts to try it out too (but not LEDs and electronics :( ). I can probably simulate with fibre...

Re: Would you recommend a tripod or monopod for macro in the field?

@Beatsy Which carbon travel monopod are you using? I use a Kirk MPA-2 Monopod Head (about £200 new) on a Gitzo GM2562T Series 2 Carbon eXact monopod (£150 2nd hand). The Kirk head was bought to use with a 400/2.8 prime (mainly sport, birds and wildlife), but it works well here too. Oh, and the pod ...
