"3D" effect?

I have a vivitar 3D lens Wink

I think best in 3D Distagon lenses..

My concept of "3D" in the two dimensional photographs is very different from what is commonly conceived.
I used to take stereo pairs of slides in the past (it really doesn't take any special equipment - just a tripod and, optionally, an air bubble leveller).
However what is obtained with that trick is not 3D for me, it's more like what I call the "binoculars effect", or it could also be called the stage curtains effect... simply said it's when you have a flat panel followed by another flat panel at a distance, and so on until the background panel.
What I mean as 3D in photographs instead is what I usually call "perception of roundness" which I think is a more appropriate definition.
Differently from the binoculars effect, the perception of roundness focuses more on the dimensional quality of the object itself, than the distance effect of the object from the background.
Distance from background also plays a role, but I think it's more important that the objects on their own are perceived as dimensional - as opposed to the typical binoculars effect.
For my concept of perception of roundness, several factors concur:

- lighiting (key role)
- microcontrast of the lens
- OOF transition of the lens
- composition of the image (this includes positions, colours etc)

I get it, but end up with a headache, especially that last one - it's too dark. I also suspect there's no money in looking like Ben Turpin any more.

There are a couple of freeware programs which dotify an image to produce one of those 'grams.


Ben Turpin?

Man I thought I was old!!! Laughing Laughing

Here's my attempt. I wasn't really trying, it just resulted. I believe it was a direct result of camera angle to the subject and DOF.

I tried both ways- front focal point & center. Between the 2, the center focused just looked better. Can't explain it but it just seemed to lift off the screen (at least to my eyes it did LOL)

Totally not MF lens, but I use my iPhone to do these




More on topic, I just purchased http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWNX:IT&item=320323445289 this on Ebay to use with my Helios 44M (doesn't have to be that lens, but apparently, that's what the kit was designed to be used on). I'll post some pics when I receive it Wink

I was just scanning some ancient slides and this one reminded me of this thread. It is Nottingham Council House, England, on a stormy afternoon in April 1981. It is shot on Kodachrome slide film, using an ME Super with a 28-70 Sirius Zoom.

Still waiting for my stereo kit Wink

In the mean time, here's a shot I took the other day. Excuse me that it's not a manual lens, but I shot it in manual mode Very Happy


It has that "pop out" quality, I think primarily because of the relatively shallow DoF (shot at f2.5) and the fact that the subject is... well, very three-dimensional at this angle Wink

I think that I made only one photo which shows kind of 3 dimensions

Got my SKF1 today. It's awesome, and works OK with on an APS-C sensor. I'm guessing that the FOV would be wider with a full frame cam. Perhaps I'll snap a few with my Spotmatic (as I have yet to own an FF DSLR Wink





Very simple design Wink





Theoretically it should work with any lens (with perhaps some limitations on focal length) as long as you have the right filter size, but the SKF1 was designed to be used with a Helios-44, so that's what I mounted Wink



And here are some pics taken with it. Best seen at this size, or maybe even smaller.

I think there must be a knack to getting the double prints about right - keep the gadget level for one thing and avoid pix with a defocussed object in the foreground. From what I can see of it (I'm no expert) I would guess it pays to 'keep it simple' and have only 2 or 3 main planes of focus in the whole frame.

What's the red turntable - Technics? Very Happy



Yeah, I'll try various things to see what works best Smile I did find out that it's obviously easier on the eyes if I trimmed out the dark band in the middle in Photoshop; also, shooting at wider apertures will give you less of that band, i.e., more actual picture. Unfortunately that will create a shallow DoF, which as you say might not be the optimal way to shoot.

And yes, the turntable is my trusty Technics SL-1200Mk-3; the red is a slip-on cover, and on the top is a Plastikman slipmat Very Happy

I have a Vivitar 3D lens still untested,

Best 3D effect what I seen from normal lenses was all Carl Zeiss lens, I remember for one what is especially good one that is CZ 35mm f1.4 showed to us by Orio and Poilu.

in the past i drew a lot. my experience there was, that plasticity was mainly a matter of

-lights/schadows
&
-perspective

and i would rate the lights/schadws above the perspective. in another thread i reminded myself of a graffiti artist i really liked. in his work, you can see, what i mean. he uses no more than light and perspective to "simulate" 3D.

especially for photography i would go with orio and add micro contrast as a main point, which precises light-shadow transitions. even if they are extremely hard or soft.
