I'm a relative newcomer to macro photography and need some advice on lighting.
I have a Nikon SB600 speedlight, which I'd like to mount on a "O ring" type of mount, something like this
in conjunction with another speedlight. Could I just use a cheap brand of speedlight here? Or will the results be inferior?
The second question is about triggering the speedlights. Do I need to use TTL cables? and how do they attach to the camera? Or can I use a remote trigger like this YongNuo 301P double trigger kit?
