NEEWER12x5 feet/3.6x1.5 meters Polyester White Seamless Diffusion Fabric for Photography Softbox, Light Tent and DIY Lighting Modifier

This is an excellent value for money. It’s VERY large. I made two 8’x4.5’ diffusion panels with just one sheet of this material. A single layer is not great for diffusing close light sources (like an LED directly behind the sheet) but two sheets are very effective. Each layer cuts about 2.5 stops of light. So, to get the same effective brightness as a bare bulb, you need to have about 5.5x as many lights or 5.5x as bright of lights to get the same brightness on the other side of the diffusion. If you double up the layers then the diffusion is incredible, but by that point you’re cutting down the light by 30x (5 stops). I opted for a single layer specifically so that I wouldn’t need as much power to get the desired brightness; however, that came at the cost of less diffusion. If you look at the pictures, you can see how clearly the LEDs are visible while looking directly at the diffusion panels. But, the actually quality of the light is perfect and suits my needs.I’m most impressed at how well the material holds up under tension, while being cut, and being held down by staples. The thickness and quality of the material is surprisingly good.If you didn’t want to put this in a frame, it would work really well for diffusing window light.

It certainly helped reduce harsh shadows on my led panel lights. It cut the light output by about 20-30% (my guess). I cut pieces from a large panel and draped it over the lights (we have cool LED lights - don't do this if you have conventional lights or lights that get hot.

I bought it primarily for my photo gear in-studio; I think this is going to come in really handy for putting more layers of diffusion on a modifier or light as I may need. I WILL say the hemming sucks, it's the worst I've seen on any hemmed product, ever. But I don't think I should care because I'll just be cutting it up as I go...but still, was the seamstress blind? I imagine it's only hemmed because it may ravel otherwise. I don't plan on using it as a window skirt or anything decorative, but if I was, I'd re-hem it. It is difficult to fold because it's such a long piece, but I managed by myself, so it's doable. As hard as it is to get anything without a seam that's this long, I think it's really a huge value.

This is a very nice diffuser with multiple ways to use it. I recommend adding it to your kit

Hard to find product that is now easy to find and order. Great size. Quality feels good and it seems to do the job. Cheap enough that I do not mind cutting it up into pieces.. I will just buy more.

On a recent video/photo job assignment, I had to work next to a large south facing glass wall with harsh afternoon sunlight. I needed a material to diffuse the light and the seamless diffusion fabric worked flawlessly. The fabric was long enough to cover the entire length of the wall at the site and the soft light it casted on the talent was amazing. Effectively, with the diffusion fabric, I was able to use the window light as my keylight. Clients were impressed and I give a high mark to the Neewer Seamless. Highly recommend it!

I'm not sure what I thought it would be, maybe more like a sheer, gauzy curtain material (one reviewer described using this as a curtain) but it's basically just like my fabric shower curtain. It seems to be the exact same material as my shower curtain. It's very long and narrow, and I was going to cut it into pieces to use, but I'm not sure what would happen to the material if I did so. The edges are hemmed, but whoever sewed the one I got didn't do a very good job. It looks like the thread tension on their machine was set too high, and the material bunched a bit and is puckered. I can also see where they sewed it once, ripped the seam out, and redid it. The holes from the ripped seam remain in the fabric. This certainly wouldn't affect any photos taken, but the bunching of the fabric means it will never hang or lay quite flat.

Was so happy to find actual Light Box Material. I have used this and it has been wonderful to work with. You get a very generous amount of it and it is super easy to clean. I just use a lint brush or roller and done. If you are looking to buy something and know it is going to work here it is. When I run out I will buy again.
