One of the most beautiful slime moulds Ceratiomyxa porioides via Kiron 105mm Macro at f16, twin flash. FOV 17mm wide.

When we found this in a local wood in 2016 this was only the eleventh recorded British find of the species, which had been thought to be a Mediterranean species. We have found it a couple of times since.



This also occurs as a yellow form. This image is not from an adapted lens but I though it might be of interest.

There is a small issue with a leg in the above image so here is another one but with not so good 3D:



I think it looks great 👍

One from this morning with theA7r3 and the Minolta MD 35-70mm at 35mm and f11. The gathering of classic cars is not a good as it could be for photography. the cars are mostly parked facing the pub. This gives an excellent view from the pub but the best shots require pointing the lens towards the sun. So there was a flare issue, dealt with by increasing contrast.

And the rear end of a Ford Ranchero, f8 at longer focal length, not recorded.

Here's an attempt to make bubble bokeh 3D:




and a completely different shot with the same lens:

Thanks.

It's a pity about the scratches. I could clone them out and I would deal with that pale spot on the fuel filler flap too. With stereo pairs you can't touch them up like you can single frames. The changes take on a depth position of their own when viewed in 3D. Anything wider than the scratches plus a tiny bit of overlap would behave that way. The pale spot is too large to fill in with colour so I would crop the individual image and remake the pair. I have already cropped out a tiny blackspot before saving to upload.

Sports cars arriving for the Classic Car meet.

Sony A7r3 with MD 35-70 at 35mm f11, crosseye stereo.

The right side is a bit tight because red car pushed its nose in between shots so I cropped it out.

On the tree on the left, two halogen lamps had been left switched on so I snuffed them out!

After some years I've rediscovered my interest in stereo images. Since I always shoot freely without a rail or tripod, most images may be lacking (which I don't really see - I guess my brain has an optimizer Smile). All images shot with A7rIII, processed with SPM in batch mode.

#1 Contax 2.8/28


#2 Contax 2.8/28


#3 Pentax K 3.5/28


#4 OM Zuiko 2/50


#5 OM Zuiko 2/50 - I know, this isn't sharp at the right spot, but I like it anyways

Nice stereos. Making the part of the scene which is +/- centre in the first frame of a pair also the centre of the second frame goes a long way towards getting a pleasing result.

I haven't used a tripod in years.

You mean that I have to pay attention to the two frames having the same centre? So far I simply chose a spot somewhere in the frame that I try to capture at the same spot (in the frame) after shifting to the side. Ok, I will try to focus my attention on that more.

That's fine, but it think it needs to be well away from the edge of the frame. That is what I do where the centre offers nothing significant.

These are from April 2016. Sony Alpha A7r, x1.4 TC*, Printing-Nikkor 150mm, f11 ISO 250 twin flash, hand held.

*Laowa Magic Shift Converter (strictly, optimised for WA) standing in for TC.



NB. Some images (not mine) no longer showing on page 6.

Hi,

very nice set of images! I love this one and - as you already know - share your type of perception... I see all of these without great effort or time to adjust and I particularly enjoy it when main subjects are placed near the edges of the frame - makes it more effective. But as you're aware it's not possible to know what works for others, unless you keep everything very safe and within a certain boundary. I've mentioned the awesome shots of Bosun Higgs already - to me they're very effective even though most don't offer the kind of exploration aspect as well as subject centering:

He always keeps his images in portrait format though, which I guess helps to make it accessibly to more people.

Here are some of my recent favorites with lots of bokeh:





(shot with a Steinheil Optronic 57 mm f/2.8 )



(Shot with a Steinheil Anastigmat 45 mm f/2.8 )

Unfortunately, the images in dpreview have a clutter of other images alongside them, on the righthand side, making it difficult for even me, of many years experience, to get the 3D effect for some of them.

Thanks,

I also like lots of Bosun Higgs' images, but not so much the type you linked. For me there's too much blur in the background loosing all the depth information behind the subject that pops out of the blur, which is nice too, but I prefer that type in 2D with the "3D look".

I always enjoy your images, this time particularly the third one, mostly due to the colors.

In Gallery mode there's less clutter and the images can be viewed much larger.

Here are a couple more experiments:






(Kyoei E-Acall 105 mm f/4.5)






(some tilted shots, taken with a Focotar 40 mm f/2.8 - I find it really interesting experimenting with that)

Finally there's another (also tilted) capture, but taken with a 28 mm lens:



(Schneider Xenon-E 28 mm f/2.8 )

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

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!)?
