Lee 299 ND1.2 Neutral Density (4 Stops) Gel Filter Sheet 21"x24"

This was used to simulate an optical quality filer for a photographic test. If one was very careful handling the material, the resulting image was indistinguishable form one taken with a optical quality glass filter.

The product was of a higher quality than the price would lead you to expect. I needed a filter sheet for an R & D trial and this fit the application nicely. Often the R & D case is a try it to see what happens and you don't want to spend a lot of money to try something that might not work.

This is the largest size I could find. The ND film is not uniform. There are "warps and weaves" in the film that are easily visible with the human eye. But if you want exposure down by 4 f-stops, you will not be able to see this texture. Cuts easily.
