Lenticular depth calculator

How to calculate the DEPTH

Thanks to Henri Clément, 3D photographer, we can show you a real comparison between many lenses on the market and we show you how to calculate the depth for each lens design.

As you can see, printing the same file on different lens designs does not make sense as each lens design has its own caracteristics. You’ll notice that our 3D 28LPI PETG-MF allows 2x more depth than a 40 LPI and half the 3D 20LPI PETG-LF. This shows why we made a 28 LPI (and not 27 or 30)…

Does this mean that these figures are an absolute limit? Of course not as it will also depend of the artwork and the tolerance of a certain amount of “blur” in the background.

Attention: the resolution is calculated in PPI, pixels per inch, not in DPI !!

In blue are the products sold by 3D Products – DP Lenticular.
