[DIY] 3-D lenticulars (success!)

[HeadTrip]

ok, I'm not very up on commercial print... I thought I couldn't do it...I was wrong!

I made my first very successful 3-D lenticular image (5x7) last night, it was tough.
The hardest part to me was finding the right lpi setting (line per inch) for my lenticular sheet.
It is sold as 60, but in reality it seems to be 59.85 (the difference is that it works or doesn't).
Then I had to print a ton of throw away images, finding the right settings for my HP printer.
The last step was lining it up correctly, thats pretty tough...

used the lenticular sample pack from here:

Heres is basic info, I'm hoping maybe this is a project we all work on together and come up with a 'newbie guide to lenticular'

1. Converted a drawing to 3D using stereopaint, ended up with two stereo images.

2. opened those images in "stereotracer"..an app that creates the in between frames based on a heightmap.
Works very well with stereo painted images, not so well for photos..so far (help needed)

3. exported the frames (12) to "superflip!" (free app to combine the images into a lenticular image)

4. printed the image on my HP printer
5. lined it up and attached to the plastic (came with adhesive backing)
I had a major issue though, it looked perfect looking straight at it until I flipped the plastic down (help on a tape hinge), once it was flat it shifted...couldn't undo it, so now when I look at it I have to tilt it slightly..its like the sweet spot shifted over...

If anyone is interested, I can throw all my settings up here...
Questions I have:
- What is the minimum number of frames needed for 3-D? is it better to have more or less?
- Whats the best way to use a stereo pair for photos?
- will there always be a shift in the image? I notice on commercial 3D lentics' that there are a few sweet spots and transition areas between. Can I make one thats full solid 3D from one side to the other?

Sounds cool. Any chance you can take a 3D photo of the setup?

I put a 3D shot on my blog...its a tough cross eye picture, but you can see the depth..i hope...

Cool.

I managed to improve the technique, decided to ditch the idea of 3D photos without a heightmap for now... Using stereotracer correctly can really yield some awesome results! So if anyone has advice for taking 3D photos for lenticulars, or a good link...please reply!

sidenote- I just ordered an Aiptek 3D photoframe! I'll post a review when I get it next week..
Is it me or did they only release a very few for sale...and quietly (hopefully I really receive the right product

Well, looks like when a seller on Amazon says "its in stock", that doesn't necessarily mean they have it in their hands...
it got delayed and is supposed to ship Sept. 22nd (from Aiptek)..we'll see

I did manage to do more lenticular tests... stereo pairs vs. multiframe depthmap based 3D... stereo pairs look amazing in 'the sweet spot'

you can use 60lpi lenticular sheet with 0.028" thickness for BEST 3D and small flips
40lpi 0.033" for BEST FLIP and average 3d
