Selens 16x20 inches ND Filter Gels Lighting Neutral Density Sheet Kit, ND3,ND6,ND9 for Photo Studio Video Flashlight Led Light Photography(6pcs kit)

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).

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.

Not real ND filter.

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.

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. 👍

These ND filter gels are functional, but they appear to be of low quality. The gel is very thin, and I am concerned that it will tear at any moment. However, the price is good and it does the job nonetheless.

Product meets the needs of project

I haven't used gels much yet in my photography training. Ok. Just fooling around so far . . . . I sure did not want to spend $$$ when I don't know much about working with them yet. I do wish they were made in the USA.
