Put simply, netting a lens involves taking a piece of cloth (like a stocking) and attaching it to the rear element of a lens. What this does is add diffusion to the “look” of that lens as well as some interesting effects that can add a distinct style other diffusion methods can’t replicate.
(To see how it affects an image, read Shane Hurlbut’s Diffusion for the Digital Age – Using Stockings.)
In the video above, cameraman Mako Koiwai shows the right way to add a net to a lens (using snot tape and some precision). His technique is brief, but excellently executed.
Thank you to Mako for the tutorial and make sure you check him out on Vimeo!
