Hmm.. that could be in general? Not too sure though. Also starting out to be a strobist too.
But how about lightbox & lamps for product shoots? Backdrop, studio lights and stands for indoor portraits?
These are part of a strobist gear too, am I right? :dunno:
Yup. If you intend to shoot with backdrops, of course backdrops and their stands are part of the requirements for portraiture. More for the formal kind. Studio lights? You mean the studio strobes or modelling light? Modelling light not necessary unless you're shooting in a dark studio.
For product shoots, better to have the light tent as it 'wraps' your light more uniformly around the product. Lamps are not necessary, strobes will do fine.
Don't forget: softboxes, umbrellas, reflectors.
