I've just bought my second speedlight. I currently have a stand, shoot through umbrella and a reflective umbrella (i.e. classic strobist starting kit).
I'm thinking that a nice softbox will be good. I will mainly shoot portraits and perhaps some 'product' or tabletop macro. In terms of portraits, probably not full length (at least, I haven't done any so far, but who knows what the future holds . . .).
So . . . any suggestions for a decent softbox? I don't mind spending a little bit of mney, so I am looking at up to about $200 for a kit (i.e. with stand and connectors/adapters as required).
Is 24' x 24' big enough?
Should I get an octobox, or square? Apart from the shape for catchlights, what are the benefits/disadvantages?
Should the speedlight be on an external mount, or internal (I'm thinking Westcott rapid box here) - I use YN622Cs, so line of sight not required.
Main use will be at home, but I would like it to be portable. It doesn't need to be small enough to hike with, but being able to carry in a bag is good (not that I expect that to be a difficulty for any setups that I am considering).
What haven't I thought of?
