Lenticular image frame rates

Hey guys
Is there any frame amount limit on a lenticular sheet or it is the printing machine that sets the amount of frames by its resolution?

Re: Lenticular image frame rates

Every lenticular sheet has lines per inch and it's not the resolution as much as how the image is interlaced into left-eye lenticles and right-eye lenticles. I'm over simplifying it, but that's about it.

http://www.explainthatstuff.com/lenticularprinting.html

So you might have a sheet with 100 vertical lenticles--50 for each eye. Let's say your stereo photo is 1000 pixels wide and 1000 pixels long. Then each lenticle will expose 20 pixels wide by 1000 pixels long for each eye. For example, 1000/50=20 pixels. These 20 pixels are then interlaced left eye/right eye and so on to cover the 100 lenticles.

Now the printing machine has to also consider it's resolution, which is probably 300 pixels per inch, so the image needs to be converted to fit it's resolution as well. Pretty much like any ink-jet printer does. So you have a combination of actual image resolution vs. printer resolution, and there is probably a sweet spot for the best image without creating a lot of noise in the image.

Let me know if that's what you were asking...

Re: Lenticular image frame rates

I simply use 'stereo photo maker' (FREE software on the web) make my lenticular interlaced images for printing. The software does a lot of things for you, corrects and adjust many factors, easy to use, works GREAT.

when you enter the micro-lens pitch (lenses/lines per inch) it will tell you how many images you can use. I think for 75 lines/per/inch it allows up to 4 images, using a 300 dpi printer. SPM does all the hard work.

When doing lenticular images, I find that too much disparity in a stereo pair do not make great lenticular prints. I had a close (almost in your face) horse 3D photo I shot, the problem was the distant background. I find that using toe-in works better for lenticular images.

Problem is (Fuji W1, W3 & Panasonic) 3D cameras seem to lack this feature. This is a case where LESS is MORE, (lens separation/stereo-base). My best lenticulars were shot with a pair of Canon cameras mounted on a bar running StereoDataMaker (sync) software. I mounted my cameras on the bar with toe-in adjusted.
