FIEWSZIHUBcolor Lighting Neutral Density Gels Filter Sheet 16x20 inches Kit, ND3,ND6,ND9 for Photo Studio Video Flashlight Led Light Photography, 6 Pcs

Tested in a spectrometer and confirm the spectral transmittance and ND values to be 0.3, 0.6 and 0.9. Took one star off because the description is incorrect, ND values are overrepresented 10x. But if you look closely in the pictures of the item, the correct ND values are shown. I bought them expecting 0.3, 0.6 and 0.9 so all good for me.

Needed a neutral density filter for video with my DSLR. The ND9 worked for bright sun. I cut out a large square and glued it to a square piece of black foam board with a circle cut out to fit the front of my lens hood. Works well.Its rather thin, could be thicker to make it more robust. I'm guessing it wont have a long life, but I have lots of leftover to make new ones.It has a slight green colour cast, but that's not an issue with digital, as it would be for film use.

Like the title says, they were shipped rolled up in a thin plastic cover (a little better than what gift wrapping paper might come in ) in a brown Amazon mailer envelop, so naturally they were crushed in transit. The crinkles and creases make these useless for my application. Further, I only received 5 sheets not 6 as advertised. The worst part is all 5 are the same ND! The package item sticker says there are "6Pcs ND-6". These look like ND6 to me, so they at least got that right.I do not recommend the product or buying from this company.

It helps keep your highlight information, but if you’re planning to use this for windows then I’d recommend buying nd gels in the feet.
