Selens 16x20 inch ND Filter Gels ND6 ND9 Lighting Neutral Density Sheet Kit for Photo Studio Video Flashlight Led Light Photography(2pcs kit)

The sheets are huge, in pristine condition and packed very neatly in a roll .

As described, note that they are quite thin gels and not stiff or rigid in any way

Works as expected. Was able to combine several for use in calibrating a telescope with flats using an extended exposure (useful for the SV405cc camera).

These gels work well for my purposes, attenuating light in a tube from a tritium light source. Because they are thin, I am able to roll them as many times as required to get the desired amount of light transmission. The would seem to be difficult to manage in a gel holder for stage lighting purposes and will not take much heat.

I live in apartment with very bright installed led ceiling lights. (I call it 'prison lighting') I got this filter kit to select the right density of film to knock down the intensity of some of the lights, and it has worked out perfectly. Just cut to fit inside of the light covers.

It's infuriating to use but that's my fault for deciding to get into something I know nothing about just to get eclipse pictures. 5 stars. Wouldn't buy again. 👍

Not real ND filter.
