Nice examples for fans of characterful bokeh Smile.

Looks fine in the first one! Well done. 👍


Thanks!

Sneakily out of bounds, I like it!

Shooting from slightly further back would have made the sides more effective.


Thanks. I actually did, but cropped it at the sides (because it seems like many people find it harder to view stereos in landscape format). You're certainly right though... that would likely work better.

Great stuff! I'm easily seduced by the somewhat overexaggerated effect, which I like in all your photos. Nice touch to break the frame with the tree trunk. How do you tilt the Focotar 40 (which is one of my favourite lenses!)?


Thank you very much! Like almost all of my lenses I adapt the Focotar 40 mm (which btw. I haven't been able to find for couple of months until it recently resurfaced 🙄) via my bellows. I have a recessed lensboard, which allows me to tilt it a little bit despite it's short focal length and flange. As you know it's a highly capable lens which also seems to extend to tilting, where most f/2.8 lenses fail pretty quickly. Good to know you like it as well - it still seems to be available for reasonable prices from time to time (which can't be said about all Focotars... 😅)!

That's an interesting remark. I have uploaded many hundreds of pairs on various websites and only a few have been portrait format. The screen shape seems to almost demand landscape.

Rhodotus palamatus the Wrinkled Peach mushroom. This young stage, with its net over the cap and the "bleeding", is instantly recognisable. When mature it is a plain pinkish bracket with just a trace of the network.

Kiron 105mm.

Very nice - looks great and such an elegant net! Quite incredible living organisms...

Here's an alternative version of the shot with the green leaves:

Thanks. Maybe it's psychology but I think the leaves are much improved.

Lotus flower. The images date from a decade ago, when the lens was probably a Kiron 105mm. I had no previously uploaded a stereo version, of which I offer crosseye and conventional.

That's one beautiful flower. Nicely presented!

Here's something from today (Zeiss Milvus 2/135, Schneider-Kreuznach SL-Angulon 2.8/28 - you can tell them apart Smile):


#1 Forbidden Stereo Bokeh, but still lots of depth...


#2


#3


#4

Those playground stereos are excellent and no kids to spoil them. Very Happy

I think this was the session when the wind was gusting frequently and quite strongly. I took one shot but had to wait for what looked like the matching wind-blown spread of petals for the second one. It seems that I got lucky.

Crosseye, conventional and colour anaglyph (loses the pale pink middle).

Fly orchid. As the EXIF data shows no lens, it must be one of my first images with the Kiron 105mm.

Nice and very educational Smile.

A few more I captured over the weekend:

Thanks. For years i had tried to get one of those, very fast running, centipedes in the frame at all. Then I got this session, of which I can recall nothing.

Your second pair has your shadow in each frame, with a very unfortunate effect on the 3D, where you seem to have buried yourself in the (transparent) ground.

You're right. However, when I tried to crop it out, the image became more irritating. I still like it the way it is now, but you need to look more towards "infinity" for it to have the effect I like about it.

I think your 3D effect is very good. I have tried scrolling down to, effectively, crop off the bottom and it looks good. Nothing about it upsets me. Of course, the now, for me, cropped out long foreground stems do add significantly but at a cost of that shadow.

Nice effect. It always surprises me, how some images that aren't too convincing as normal photos, become interesting and wonderful to look at when viewed in stereo. The forest images of blotafton are also particularly stunning, when viewed in stereo, but wouldn't catch my attention, when viewed alone.

I have a few more from yesterday and today, lenses used were the Nikon AI-2/24 and the Leica Elmarit-R 2.8/28 v1:


#1 Elmarit


#2 Elmarit


#3 Nikkor


#4 Nikkor


#5 Nikkor


#6 Nikkor


#7 Nikkor


#8 Nikkor


#9 Nikkor

Thanks. You now share my opinion of 3D over 2D. I would add that the 3D can often enable us to understand more about the subject and maybe also its relationship to the surrounding scene.

Here some "invisible light" i.e. reflected UV images of Bidens

Visible light:



in 3D crossview UV:



in 3D parallel/cross UV:



Note the very strong UV pattern we humans cannot see! Bees do and always land on the UV bright side, then crawl to the UV dark part to find nectar (scientifically proven fact)

And here a test I tried to show both VIS and reflected UV in 3D-Stereo (cross)



This is a RUDBECKIA flower

Wonderful shots 👍 And interesting information about the behavior of the bees! They are such fascinating creatures…
