Thank you, Brian - useful to know. I tend to use the Lite OWL as my reference viewing platform, so some of these close ups may be difficult for freeviewers.

As for the problems with the W3, tell me about it. I quite often slip the camera into my jeans pocket and that rear dial gets moved around one or two steps to settings that require sequential operation like that. V frustrating. One day I might look at whether I can do the landscape images they talk about in that manual (sequential images from a moving car ...).

So, to right my earlier wrong, I took a quick trip to Bourne and, for the first time since moving to Lincolnshire, took my a7iii and the Fujifilm 3D W3 for a walk. The weather was very showery so these are just a sample and I hope they work okay:

First four:

and the final four: Bourne park 4 and 3 are very similar, 3 is just a bit further back, but I have left it in for the balance









They are all scenic and don't contain too much to give the impression of depth, so next time I shall try a few close-ups.

Brian, I think they do give a sense of depth, especially the bridge scenes and no.1 with the tree trunk on the edge of the frame.

My frustration is that until just now I didn't know how to change the size of the pictures on my iPad (the answer is to tap AA in the address bar and in my case reduce size to about 85%), then I can use my OWL viewer. That helps enormously and I find Nos. 2 and 5 work well too.

Are these all W3 photos, or have you been trying out the 'cha-cha' method with the A7 III?

All from the W3. Unfortunately I was carrying my a7iii with a Batis 85mm on a peak design wrist strap so when I pulled the W3 out of the bag I had to let the a7iii dangle, which tightened up the strap cutting off my circulation    So I didn't give the W3 much of a workout.

And so to a trip to the garden centre where I thought closer subjects might present themselves, following a bit of coaching from Howard:

They all have pleasing depth, Brian, and the main subjects are all at a distance that plays to the W3's strengths. I feel I can almost hear the water tinkling in the background. The leaves in #1 are striking, and I like the way the depth in the flowers in #3 is apparent. The sundial is a good subject, but the supporting table doesn't quite fit the frame and is truncated on one side.

TFS!

Thank you Howard. I agree about the sundial but the garden centre presented lots of closer 3D opportunities. I think my favourite is the fish tank in the aquatic halls. And BTW, congratulations on reaching 3000 posts

Blimey, 3001 now!

I am falling behind in my photos and challenges, but let me put these up from Holme-next-the-Sea in Norfolk. I wanted to try photographing clouds in 3D.


Norfolk cloud stereo/3d
This is a standard Fuji W3 shot, no tricks. It's quite flat but there is a small sense of depth towards the horizon, and with the bright clouds behind the darker ones in the foreground.

I really wanted to try 'hyperstereo', which is where the distance between the two shots that make the photo is greatly extended. The rule of thumb is that the separation between two shots should be about 1/30 of the distance to the subject. How far away is a cloud? If I say 1 km that means the two shots making a stereo pair should be 30+ m apart.


Norfolk cloud stereo/3d
Here I used the W3's capability to take the two pictures that make a pair separately. I took the first, walked 10 paces, and took the second. I approximated the general direction. The rear LCD is meant to show you the two pictures overlaid, but it was too bright to do that meaningfully. Good old SPM did the work of alignment. I think here you can see that the cirrus clouds are behind the cumulus ones.

I tried it again


Norfolk cloud stereo/3d
And here I aligned on the horizon line of dunes and trees, and I think the clouds are behind this, with the cirrus clouds further.

Wow Brian and Howard, very nice, most of them work nicely with my viewer when I reduce the size on my screen 2 steps. Only one that gives me a problem is Brian's rhodondendron, it really never pops into place but all others work very nice. Also all of Howard's clouds work nicely, you can really see the cirrus behind the cumulus and the "hole" in the clouds above the beach.
You can see the April Foolishness 2021 exhibition here Another great show of the talent we have on Dyxum

Many thank yous Pieter. I understand what you mean about the Roddydoddy (as my son used to call them), I initially had a problem with it free-viewing, but found that by not focussing on the flower, but on the leaves to the left it worked okay.

I also feel guilty using a Fuji digital camera for so many shots here, I'll have to start using the Stereo Realist and post them in the film thread, or finally get the twin RX100iii rig set up, although that isn't A or E mount either

Guess I'll just have to use the a7iii on the sliding rig again.

Howard, your last clouds pair is really great. The separation between the lone cumulus on the right and those lower down with the cirrus so much further back is amazing when the "magic" happens.

Yes, thank you both for your comments.

Brian, hand-held sequential shots are a breeze in SPM, which can be quite forgiving of misalignments, but there will always be an advantage in using a sliding rail.

Here's another shot using an adapted and modified Panasonic 3D lens on the NEX-7 (adapted to mount it on the E-mount body and modified for close-ups at 10-15cm, better suited to the twin-lens separation distance). SPM takes all the hassle out of extracting and separating the pair of images and after swapping Left and Right will align them quickly. This photo is uncropped, which seems to work here:

The onboard flash was used too.
