FMP lenticular

I made a stopmotion taking the images every 30 seconds. The gaps where a bit much hence the reason I started experimenting with the morph effects in Premiere. That was much to heavy for the computer to calculate but it gave some nice transitions.

That is the reason I exported 18 frames to see if I could make a lenticular print with it.

40 lenticulers per inch is 18 pixels.

On the site: http://www.vicgi.com/lenticular-interlacing-algorithm.html I followed the steps with some alternations.

Doing maths to see the amount of images I need.

N = Needed images/layers

Rpr = resolution printer (720 /1400 since I have an Epson printer)

Rl = amount of lenticulars on the sheets (I have several different sheets 40 and 60)

720/ 40 = 18 images/layers

720/ 60 = 12 images/layers

720/ 80 = 9 images/layers

720/120 = 6 images/layers

1. Place 18 images in a photoshop file for the 40 lenticular sheet (import > load files into stack).

2. I changed the image size to 720DPI and within 8x10 inch (the size of my sheets).

3. I didn't have to do something about the alignment because the morph effects took care of that.

4. I made a pattern to have 1 white and 17 black pixels and filled the mask with it. That made it easy to fill the mask with and I can use it the next time which saves time.

5. I copied the mask, unlocked the layer from the mask to shift it one pixel; 17 times.

6. Then I merged all the images.

7. Now I just have to print it and find my sheets.

A close up

I printed the first one but couldn't see if it worked; the contrast was not high enough. For the second one I changed the contrast and it works.

My sheets are vertical and my image horizontal so I have to make the next one smaller or buy new sheets.

I don't have a cold laminator; have to get one. The first results:

What is this all about I asked my self, how does it fit in with my project?

This is about transformation as you might be able to see in the images below.

18 images used to make one lenticular print show a transformation from the first to the last image symbolic to the way clouds are changing.

I made 3 of them and stick them together some internships helping me with the laminator.

The last of the 3 was the first that we did; we skewed it a bit not on purpose but I like the strange outcome.

Now the 40LPI sheets are finished. I have other sheets and started to try to use those. They are not in a pakkage so I had count the lenticulairs first. Having a magnifier I see that they look different.

After trying for a day with my other sheets I came to the conclusion that I might have the wrong ones. I googled it to come to the conclusion that there are 2 different kind of sheets: flip and 3D. The difference between the two designs is the viewing angle.  A lenticular lens sheet designed for 3D images will have a narrow viewing angle (typically less than 30°).  Conversely, a lenticular lens sheet designed for flip images will have a wider viewing angle (typically higher than 40°).  Morph and animation images can be considered advanced flip images and will also benefit from a lenticular lens sheet with a higher viewing angle. 

A good moment to buy more of the 3D sheets and go making some flip images for today to see whether the theory is correct.
