With my collection of modifiers growing I thought I'd take inventory and also take stock in the various exposure factors of the modifiers. Specifically with in-line diffusers like diffuser screens and soft boxes.
Because the source materials for many diffusers come from a wide range of readily available products, knowing how much light a particular piece of material blocks can be a handy bit of information. So with no particular scientific procedure in mind I set out to determine light loss from the various types of materials I was using in my modifiers.
For a quick rundown of what I had to deal with here is a short sample of some of the materials I have in my collection; bed sheets, window sheers, shower curtains, wedding dress material, metal and nylon screens and a few other miscellaneous resources. You can see my use of window sheers and a piece of a hacked up shower curtain in the photo above.
