I've got a problem with my slave flash.
I am pretty new to cave photography, and bought an external slave flash to enhance my digi camera that has a weak flash. It seems that it does not always want to flash unless it is less than 3 feet from the camera. It is a cheap "Digital Concepts" slave.
Is there anything that I can do to fix this?
Is there a better, inexpensive slave that I can buy that has better sensitivity?
I've seen pictures where the person in the frame is holding a slave behind them and it works. Mine will not do this.
Should I mount a reflector next to the sensor, or turn off our headlamps before I take the picture?
Any advice will be greatly appreciated.
Some of my pics have been uploaded on "onlinecavers.com" and they are labeled "Howard's Waterfall cave" by anthony. Please share them if you like them.
