Re: 3d Lenticular photographer: Henri Clément

Just another point about my custom Image Tech 3D1000:  As I mentioned, I got them to add a PC sync port for use with studio flash.  Of course, I could have used a Nimslo since that one already had a hot shoe for flash.  But the point was that Image Tech only processed three of the four negatives.  So the fourth negative for each Nimslo image set was ditched.  Using the 3D1000 allowed one to not waste film !

Listening to this...  a few comments:

* The company was called "Image Tech".  They only modified the name to "3D Image Technology" near the end.
* I followed a similar path except I started out with the Nimslo in the 80s.

When Image Tech came around, their first camera was the "3D1000".  This one had a motor drive.  The one that Henri showed was the "3D Wizard", a later, simpler model.

I corresponded for years with Image Tech vice president Sunny Ip.  I had him add a PC sync port to my 3D1000 so it could be used with studio lighting.  I also got at least two special slide bars from them.  Then I devised my own program to calculate lens separation based on distance.  This was actually patterned after an analog calculator dial they supplied with the bar.  They wanted me to send it to them for free.  I said no !

They also had a 5-lens 645 Pro camera but their price for it was outrageous: US$18.000.  Near the end, they were working on a 35mm version with interchangeable lenses.  The camera did not get marketed during Image Tech days.  But when Allen Lo went back to Hong Kong and founded a new company called - amusingly enough "US Tech", he completed that 5-lens 35mm Pro camera except that, instead of interchangeable lenses, it came in the form of two cameras - each having different focal length lenses.  There was a Portrait camera and a model with wider lenses for general photography.  I almost bought them but was worried they might also go out of business.

A friend of mine made these two stereo pinhole cameras.  You can download the plans & print them yourself.

STMANI3 can only align stills, not videos. I just aligned an SBS frame from the Kula bebe video, close to the one shown by Etienne.

The keystone deformation was easy to correct, I got a maximum vertical error of 0.05% of the height as shown in the LRL below. The trouble are some glossy features that look different in each image. One white strip apparently from the tennis net, and another glossy features above the trash bin at the lower right corner. Perhaps they are a shortcoming of the beam splitter in the lens.

I moved up a little bit the lower margin to hide the YouTube controls that disturb the stereo view:

I'm unable to find intelligent life on earth (not worthy of being capitalized), so I'm looking elsewhere until further notice:

just 2 or 3 connected. Will try to get 10+ next week as a test before February's meeting.
I hope to be able to make another front end for the presenter, utilizing thumbnails generated by stereophotomaker (what it makes for its web gallery)


PSA Hollywood Stereo Exhibition 2020 Video screenings

Andrew Parke
 

I am writing to ask if any other 3D Clubs would be interested in screening the PSA Hollywood Stereo Exhibition 2020 Video at an upcoming club meeting?

Part of the PSA requirement is to screen at other venues. The video on YouTube can be anaglyph or Squeezed side-by-side depending on your viewing method: https://youtu.be/ZHS-c2_MSfQ

We also have an HTML5 Gallery of the Exhibition Entries here:
http://la3dclub.com/la3dclub.com/competitions/Hollywood20/gallery/index2_m.html

The Hwd3Dx20 CATALOG of Entries:
http://la3dclub.com/la3dclub.com/competitions/Hollywood20/gallery/HWD3DEX2020-CATALOG-Final-5413.pdf

You can find a master link to all of these items here:
PSA Hollywood Exhibition 2020:
http://la3dclub.com/competitions/psa-hollywood-exhibition/

Let me know if you decide to screen the video. The HTML5 Gallery is there also which has a variety of viewing methods built into it. Also, let me know if you ever want our club to screen a PSA exhibition for you in kind. Thank you.

ROOMS update:
- There is an alias address easier to remember: https://rooms.stereopix.net/ (it is a full page frame redirecting to the other site)
- If you have a JSON file on your server, you can type its URL instead of its content, which would make the browser of the presenter download it.
- You can give direct link to the room with the alias address above followed by your room's name. (If you include it in an iframe, you could also use the real address; when included in an iframe, do not forget to add the permissions for fullscreen, webxr & co).

Hi Michael,

That's great!
Henri is really a great guy.
He was kind enough to do a lenticular workshop for the French Stereo Club in Paris in 2012 and also to organize a visit of his studio (full of wonders!) in Paris in 2017.

I has a chance to do a video interview with French 3D lenticular photographer Henri Clément . Henri discusses his tools and techniques for 3D portraiture and 2D to 3D conversion.

Enjoy,

The procedure is exactly the same in MacOSX, if you are a Mac user...

Antonio, I know your Linux program has this capability. Alas, I don't have a machine with Linux.

If your are interested, it's very simple to install Linux (for example Ubuntu, or my preferred XUbuntu) in a VirtualBox inside Windows. It's something everyone can do, without any risk for the machine or the Windows configuration. I may give you some help if you want.

Googling "VirtualBox Ubuntu Windows", I found lots of pages explaining this. This one, for example, is a quite good step by step explanation:

https://gadgetliv.com/install-ubuntu-on-virtualbox-in-windows/

Remark: Windows 10 also offer natively the possibility to run Ubuntu smoothly inside it, but this is without a graphical interface (only a command line interface). You may also install a graphical interface (what is called a X Server), but the configuration is a bit tricky to build.

This said, you should know that installing Antonio's software will require some minimal developer skills.

Wrong, I also repeat that ANY keystone deformation can be exactly cancelled with an appropriate perspective alignment. Keystone (Toe-in, Toe-up) is just a perspective misalignment, which is equivalent to two perfect cameras pointing at different angles.
Of course this can only be done on digital photos, not for film.

Hello guys, my apologies for "spamming" my message around - but i really need help, as I dont have much knowledge as well as ressources for marketing.

I've been working on this for quite a while. I hope to gain some interest in the 3D Community, but also to draw some new people in from the analog world.

The idea is to offer a DIY Assembly Kit alongside the finished camera, to make it more affordable to beginners ... do you think it makes sense ?

I got an e-mail from Dominik as well - and advised him to join this list:-)
Although my interests are a little bit different, I definitely like his graphical presentation and neat execution of his projects!
