Hi everyone, An old lady here in town gave me some older photography lighting equipment for free, a painted backdrop, light stand, some barn doors ( silver reflecting looking ) and some lights. They look pretty old... silver bowl looking. I am too new to know what they are, but are the worth using? I got some umbrellas too, which are older, but fine for now. I thought it was very sweet and didn't want to say no, but don't want to keep equipment if it's not worth using. Any input would be appreciated!!
