[Nikon SD-400 with diffuser.]
Flash
I have all kinds of flash equipment, mostly Nikon, plus various
frames and extenders. I don't like flash for close-up photography (I
tried it for a couple of years) and now never use it, so I am not
going to recommend it to you. Also, I am not up on the latest flash
gear and probably never will be. I understand the value of flash and
appreciate its use for close-ups in some cases, but am unmoved to
actually make use of even what I have. Sometimes I use the
smallest Nikon flash, the SB-400, with a soft diffuser.
