I do enjoy the diversity of projects on this forum. Fantastic stuff.

Hi Sam, thanks for your comment. I didn't know if these would work given how fast the plasma streams move and dance around and yes the corona is blurry when you watch it in action. You are correct, in that a synchronised exposure is essential, but although this was a first attempt at making a stereo pair with this plasma light, I took three shoots, the first shoot the cameras were not close enough and the second shoot only the right hand camera fired. I used the self timers on the cameras and pressed both buttons at the same time, which eliminates any movement on the cameras that my figure actions may impose, but it does show how good the timers in the cameras are, and the serial numbers of both being a difference of 4219. The shutter count on the second hand camera is currently 6098 higher than my own original camera.

Regards Nick.

That’s a very effective result, Nick … and an inspired choice of subject !

To do any better, I’m pretty sure you would need a pair of ‘global shutter’ cameras

… but would the ‘accuracy’ then diminish the artistic effect, I wonder. dont know

Hi MichaelG, had to look up about global shutter cameras as it's the first time I've heard of them and yes I can understand the difference that they may make, but I think the price of one let alone two, may be outside my budget that I would want to pay right now. I did wonder if my experiment would even be successful, given the nature of the speed of things, but I was very pleased with the result. I guess such cameras could diminish the artistic effect as you say and may make the pictures look too clean, but probably would be good for a serious study of the events.

Regards Nick.

I happened across this image yesterday: **LINK**

Not much to be impressed by when the page opens … but try zooming-in !

I feel sure I shall find some practical uses for screen-shots of it.

The rest of the site is worth browsing too

That's amazing, Michael. Made up from so many photos stitched together.

What size printer could print it out?

Beyond comprehension, Bill

… but what I will probably do is use it as a source for screen-shots of the individual elements, which the iPad will do at a decent resolution.

Edit: __ for example: I have just done this, and converted it from png to jpg for the forum

… which should print nicely on A4

Hi, yesterday after mowing my lawns, and being it was quite a blustery day, I tidied up some small tree branches, where upon I found several Conkers had also been blown down, which reminded me of childhood days of looking out for conkers and having Conker challengers with my siblings and with school mates at playtimes. (I lost mostly) Having collected quite a few up, I though the collection would make a good Stereoscopic pair. So below is a parallel view first and a cross view second.

See what you think.

Hi, MichaelG, thanks, I was a little concerned whether this would work, as it wasn't until, I posted them here, that I noticed one image has been cropped slightly wider than the other, but both the views worked OK for me, although the cross view one looks muddled, as they normally do for me.

Regards Nick.

Conkers ! that brings it all back... I tried pickling in vinegar, baking in the oven, ageing in the airing cupboard, all kinds of hocus locus but never could get that unbeatable smasher...

Thanks, Nick.

That’s another neat subject. Your front-to-back layout certainly makes the horse chestnuts jump-out.

Clearly, within the limits of dof (depth of field), extra depth adds dimensional impact. The cropping issue you mentioned made no difference to my cross-eyed view of things. I also feel sure others recognise how your efforts are showing us the way, and providing both parallel and crossed pairs is also very much appreciated.

Having plunged into his thread with a (3D) ‘branch line’ (back on Page 6 - 22/05/2020), I wonder what Raphael makes of all this.

By the way, in my neck of industrial Lancashire, conker contests were a rarity, but certainly preferable to clug feh’tin (clog fighting) .

Never actually entering into such a sporty pastime, I stopped wearing clogs upon leaving primary school.

Keep up the good work.

Sam

Hi Sam Stones, thanks, my cameras were set on A-DEP and the 18-55 lenses were set on 18. The subject was illuminated by a daylight bulb. Good to know the cross view worked OK, but I'm a bit miffed with myself for not getting the two images an equal width, but it just shows how good one's vision is.

Sam Sokolik, I'm also impressed on how good your photo is.

Regards Nick.

A stereo pair with a big difference, i.e. not macro.

Sorry guys, although someone might do the switch, it's only for cross-eyed viewing.

Sam, can I suggest when posting APOD links such as this that you don't use the direct link. Instead,

- go to the page

- click on the "previous day" arrow at the bottom

- then click on the "next day" arrow

Which will get you back to where you thought you started except that it now has a fixed url containing the date.

Like this **LINK**

The link you posted will have moved on tomorrow!

The beauty of macro photigraphy is apart from the equipment its not expensive, you don't have to travel, its all in your yard/house/workshop around you.

If you can photograph something on your lens, you added enough extenders between camera and lens.
Thres also the F-Stop thing where you isolate the object from the surroundings, if you focus and place it around you mind find interesting colours appearing you dont otherwise see like that.

A blue vice in your workshop in the background may become a colourfull stream of blue light addition without anybody recognise it as a vice behind your object, choice of F-Stop to regulate depth of field.

In the beginning its very confusing using from macro to telephoto lenses, but there is an easy rule I follow, the nearer you get to the object the larger the F-Stop setting can be and still isolate the background, or the opposite, does not matter which camera, which lense used....The F-stop thing..,. The depth of field can range from millimeters to kilometers depending on distance and lens and aperture/F-Stop.
