Question: are the Prism Backdrops 10X12 Muslin Photo Video Backdrop Background-White made of fabric or are they solid pieces
Document: You can't get any better than these muslin backdrops. They are heavy, color is pure white, and hang beautifully. Definitely recommend for any photographer- pro to novice. The added free bonus of a storage/carrying case will keep them clean for travel as well. It wasn't even listed in the product listing!Wrinkle removing trick- Hang it up and stretch it with 3-4 muslin clamps to your frame (each side). Spray mist it with water and let it dry- 20-30 minutes.
I purchased this as a backdrop with my SP2000 Background support stand. With some additional clips I purchased, I was able to keep the backdrop taught enough to remove most of the wrinkles. I did not bother ironing it before hand and very few wrinkles were visible. The nice thing about a white backdrop is that with the proper skills and lighting, you can make it appear white, grey, or even black.
This is a particularly cheaply made backdrop, but is doing an &#34;okay&#34; job. I decided to light it separately from the back, to minimize the shadows caused by front-light on the subjects (especially noticeable on the white backdrop).The one I received had a couple of rust-colored spots on it. Washed it (mostly to remove the wrinkles), and although the spots faded, they're still there.
This Prism backdrop was what they said it was going to be, and very very fast shipping. If you are needing a backdrop this is the way to go.
Nice background for the beginning photographer. Kind of thin so don't place it anywhere the light will bleed through from behind otherwise a great starter backdrop.
It is such a pain keeping these huge backdrops wrinkle free I just keep washing and drying them hoping they will come out wrinkle free, but you have to immediately hang them up or they will just wrinkle again! They look great as a backdrop though!
This was thicker than I expected and I haven't seen anything through the back of it in my pictures. It is a little wrinkly, but it's fabric, that happens.
It WILL flatten and you have little "elbow effort" to make it happen. Try it, it really works. I discovered this with a REALLY heavy green screen muslin and could not believe how easy this east to get "wrinkle free".
it is white and it is big.. umm what else are you looking for in this product ...price?well that I can not comment on since the price changes all the time.
I'm not sure if there's a trick to this, but there is no easy way to get the wrinkles out of this background. It's so big that stretching it out and ironing it is out of the question. I've heard steamers might work but didn't get a chance to try one. I just switched to a rolled up paper background.As far as the quality of the product, it was OK. The material was thin and frayed along the edges, but nothing too bad.
Answer: They are fabric (thicker than a sheet) you might need to throw it in the dryer before the first use to get the wrinkles out :)
