ENDED - Winner Announced - Official PrinterKnowledge Picture Contest #2

[fotofreek]

Are you using a digital stereo camera? As I recall, there is also a technique for using a non-stereo camera with a tripod mount that permits the camera to move a measured amount to the side for the second shot. This simulates the two images that your eyes would see separately that are fused in the brain to create depth perception.

I have stereo slides of a family gathering taken by my uncle with his stereo camera more than 70 years ago. He was a camera buff and had several very nice cameras. He also set up studio type lights to take the family pics. I also have two stereo viewers and stereo pics of national parks that were available in the park gift shops. The viewers are wooden devices that work quite well.

I can only see it in mono and it looks just great to me, but then I have the advantage of enjoying this lovely photo again viewing the second one..

A 3D (stereo) crosseye view.

Yes, that's stunning in stereo.

I've never viewed such large photos unaided in stereo before. It never occurred to me that you can view them cross-eyed. Since these photos are arranged for cross-eyed viewing, I guess that also means that you have to view them unaided--that you can't use a normal stereo viewer.

Stereo Photography is one of my specialties! That's one of my specialties for printing!

Most of my stereophotography can be found here:

I print stereo Holmes cards (7" x 3.5") for classic stereo viewers that are sold at a local non-profit museum.

Mostly I take stereophotos with a single digital camera using the "cha-cha" technique (shift about 3" horizontally between "2 shots) and use StereoPhotoMaker freeware to align, crop and adjust them.

There are many options for viewing stereo photos. Cross (my favorite), parallel (works in most viewers), alaglyph (red-cyan glasses) which I hate since it distorts colors, above/below (works for some 3D TV's and special viewers), and several more.

I've used film stereo cameras since to 70's.

In the 1970's, my neighbor's eyesight began to fail, so she sold me her f3.5 Stereo Realist so it could continue to see use. She used it VERY heavily for at least 20 years. I used it just as much for over 20 MORE years, until I upgraded to an f2.8 Stereo Realist. It still worked well when I sold it! The Realist is a very sturdy, simple camera. In a pinch, it also can be used as a weapon!

I couldn't afford slide film in those early years, so I fed it re-spooled B&W film, processed it myself, and made Holmes views in my "darkroom", seen here...

To produce a single antique Holmes (3.5" x 7") card took about an hour (not including drying time). How things have changed!

I had produced HUNDREDS of negatives that I've never seen printed or made positive. A modern film scanner is changing that rapidly....

Slides and Negatives presented here:

https://www.flickr.com/photos/turbguy/sets/72157622321846829/#

...were scanned with a CanoScan 8400F and 9000F scanner, cropped and re-aligned with StereoPhotoMaker, then tweaked (levels, curves and color balanced) and sharpened with Photoshop. Recently, I have discovered that even very dense negatives can be successfully scanned by fusing three scans at different exposures with Photomatix software.

The scanner can recognize dust and scratches on E6 films and "removes" them. Sometimes this produces small spot "retinal rivalries" as the software "fills-in" or clones the obscured image with extrapolated data from surrounding areas. Spots/scratches on black and white negatives cannot be detected and these remain in the displayed image.

The Stereo Realist can have some "Quirks". Some users have called these quirks "features"! It was common to experience a small light leak on the right film chip using modern high speed (100 ISO) films due to an inadequated film door seal. These remain in some of these scans. Another is a slight difference in exposure between pairs. While the shutter is fully sychronized, the irises are not so precise. The scanner will pick up these slight exposure differences and some of this shows as "retinal rivalries" in the highlights (typically in clouds). The solution was to always set the lens aperture from one direction to compensate for very slight "slack" in the iris adjustment mechanism.

An example of both "features" is here:

The f3.5 Realist lenses will vignette heavily when used at f16 or f22. Here's an example:
www.flickr.com/photos/turbguy/4468636702/in/set-721576223...
It's best to go no smaller than f11 to avoid vignetting. Some of this vignetting can be seen in the scans of early slides and negatives. The f2.8 lenses do NOT vignette at small apertures, and will produce superior photographic results overall.

I also acquired a Fuji 3D W3 Digital cam, and have learned how to exploit it.

@turbguy - Great description of your journey through 3D photography!

 

[3dogs]

@turbguy - brilliant skies, and thanks for the intro to stereo, I had no idea it could be so .........real!!
Thanks
Andrew

Can someone PLEASE pòint me to where the Unofficial Printerknowledge Comp. 2 is hidden as i would like to post some pirated images I took of unsavory subjects on contravercial an provocative subjects. Bad news sells.......good news does not get published!

 

[Emulator]

@3dogs I thought you had fallen asleep - utter silence for days - but now you've returned to cause more trouble!

When did I wake?

A fella has Standards to maintain ya know

 

[Emulator]

Yes, you maintain your standards OK. PK is all dreamtime really.

Been watching a series of TV programmes "Coast Australia", really excellent. It follows on in the style of the UK programme series. Fantastic scenery, colour and scale. All about the area around Dampier and Montebello tonight. All about the inhumanity of Norfolk Island last time.

The scenery is of a style not seen in many countries of the world, impressive enough to compete with some of turbguy's images.

We have not seen Coast Australia, sounds good as there are MANY places I may never get to visit myself. The UK version is seen here and my observation is that the coast around you has a 'homey' feel to it probably because its productive land right down to the beaches in so many places and a rich history that resonates with folks that have been exposed to the British Empire. Not saying all places but a lot more than us.....There is a harsh edge to the entire continent of Australia that is not apparent in these shows and our White history is but 200 years. They tend therefore to avoid extremes. For example they dont often show when the weather throws a tantrum on your coast, that will make the news, likewise here, these shows tend to occupy a travel invitation format making a broad pitch to the general public to investigate travel opportunities to these far off places.

The Top End closer to the Equator is big horizon country where spectacular weather events make for dramatic images. Like Scotland our High country can really "spit the dummy" and present the viewer on the ground with multidimensional excitement in extremis!!

Interesting you mention @turbguy his photo of his photo studio got me to thinking if I could do the same.......
Sooooo! out to the shed I went to search for spare cardboard, scraps and bits and pieces to construct a cartoon Studio of my very own
Here is my Studio compliments of a Phone App called Paper Camera.........
