I would say, "You're kidding," but I fear you are not...

In their book, Macrophotography: Learning From a Master, Gilles Martin and his writer, Ronan Laoec, mention on p 266 a home-made device "...inspired by frames used in underwater photography..."
Very briefly, the device consists of a highly visible frame supported on the corners by metal rods that connect to a camera holder on the other end (the camera itself looks to be enclosed by a wooden frame). Apparently, the visible frame would enclose an aiming area surrounding the focus point. The operator then aims that frame at a flying insect and fires the camera when the bug flys into the aiming point.
Of course, the photo on p 266 gives a far better notion of the method. I'm interested to learn of any experiences with a similar device, or opinions about it. It's 0530 local time here in Central FL, and I'm still asleep -- please don't hesitate to let me know if clarifications are needed.

Nickonian72, I'm already indebted to you for the set-up you showed a while back. I'm using it now, with a Micro-Nikkor 105 mm and 2 speedlights: a Lumopro LP 180 with a Fotodiox 6x9" diffuser and a Viltrox JY67ON ringflash. The LP-180 is slaved to the ringflash, btw. The Lumopro/diox extends over the end of the lens to eliminate its shadow. Usually, both flashes are set to 1/128 pwr and the shutter to 1/250 sec. This arrangement helps to reduce motion blur. As you point out the light is pretty weak. Yet, within only a few inches from the lens, it seems to do some good. Of course, the working distance is pretty small, and moving in this close does scare off some bugs. Hence, the employment of the Tamron 180mm lens. I'm going to pursue using the same set-up as with the Micro-Nikkor 105, just to learn a few things, but I'm already preparing to try one or more of the ideas presented in the URL you've cited. Muchas gracias!!

I'm impressed. The only component not in there is an oil immersion objective!

Thanks! I've ordered the down-sizing rings instead. They might even be handy for my 67 mm polarizer as well.

Thanks, Jeweler53! Yes, 67mm was the largest in the box. I suppose I could buy a 72mm (lens size) and then have a machinist cut that down to the OD of the 67 mm, but that'd be like killing ants with dynamite, I suppose. I'll go for the Neewer set. I'm grateful for you advice.... ~jessM

1xMetal Adapter Ring 67/72/77/82/86mm For Cokin Z Pro Hitech Filter Holder Kit

This set of adapter rings is offered on eBay at less than 9 USD, but the seller can't say if the rings will fit (thread match, etc) for our new Tamron 180mm macro lens. All we need is a 72mm adapter ring for the Viltrox JY67ON ring flash which mounts on the adapter ring via a clamping system. A 72 mm adapter was not supplied with the flash. We'd be grateful for any advice... 73... ~jessM
PS: I've never used the the Cokin Filter Holder, so I have no understanding of how it "fits" a camera. In any case, this question relates to the rings, not the holder.

Kpmac, that is one gorgeous Anole. We have them aplenty here in Cocoa (Port St. John) FL, but ours are not so attractive. Your image is wonderfully composed, a really attractive shot!

PS: For those who've never seen one, here are two "lovebugs"-- in their usual state. They fly around this way as well, but we've found them hard to photograph.

Some of those electronic lightning detector/trigger widgets work OK, but I've not decided myself on which to buy. I have heard. though, that the better ones are also the pricier ones. I like the suggestion of finding a pitch dark place and using the BULB setting. Try various openings, beginning at f/11 and upwards. That's just a SWAG. Have fun... 73... ~jessM

Yes! 'Twas the "Dirty Duck." I regret not going in for a pint. Had to see a play -- produced by one of the Monte Python boys. Awful. Royal Shakespeare did it much better just N of Londinium… :-)

About 20 y ago, that was the text on t'other side of the "Black Swan" sign. Perhaps there's new management who have no sense of humor.... :-)

I remember a pub with a sign: on one side "The Black Swan"... on the other "The Dirty Bird." Or something close to that … 73... ~jessM

Thanks to everyone for the comments. BTW, that's a male Agepostemon spp. Females are metallic green all over, but males wear striped britches. I'm really not that smart, but I know smart people... 73... ~jessM

Ah, tweak AND rock...
I'll try it, Mark. Thanks! I'm on my way to Carnegie Hall... :-)
... practice, practice, practice...~jessM

Thanks for the reply. I agree about the background concern. You would not want to change exposure of the whole image. I was thinking of spot lightening using Lightroom's Develop Module, specifically the adjustment brush. It's been a long time, but I remember brightening an eye once. It can be done in Photoshop as well. I'll hasten to add that I really like your image as it is. Lightening the eye -- just a touch -- was just a thought, as that might make it more prominent, so viewers might notice the great focus..... regards, ~jessM [No reply necessary]
