I'm in the market for a light modifier, but the list of candidates has me dazzled... umbrellas, soft boxes, brollies, barn doors, snoots, and all sorts of exotic thingies. But as I understand it, the Strobist approach is based on simplicity and ease of use/portability, and some of these attachments are big and complicated... as well a expensive! For example, I can buy a 45" white umbrella with a removeable black backing, which means I can shoot into it or through it, for $29, but a 46" Softliter II will cost more than twice that amount. And I've been warned that it's "complicated" to attach an SB800 to a Softliter. Help me out, folks. I only have little 32" white umbrellas (with black backing) that came with my B&H lighting kit. http://www.bhphotovideo.com/c/product/425220-REG/Impact_DFUMK_Digital_Flash_Umbrella_Mount.html They're too tiny to light a group. What would you recommend? Keep in mind that I'm geometry challanged, and need to Keep It Simple.
