[QUOTE="WayneF, post: 360707, member: 12496"] Sounds very mysterious... if it is operated as a continuous light, it should just work. Sounds like your manual exposure must be insufficient for the low power level. Try one time setting camera A mode, start with a wide aperture, and let the camera meter it. It can go to 30 seconds if necessary, so higher ISO if necessary to prevent excessively slow shutter speeds. Seems like a continuous light cannot Not work. :) I think it must be this light: [url=http://www.aputure.com/blog/2012/03/16/amaran-halo-ring-flash-led-released/]Introducing Amaran Halo LED Ringflash - Aputure Blog[/url] There is a Support menu there, with contact access link to email them. Or a phone number. Ask them. It says continuous is 6 watts, which is not much... A 1/100 second shutter is open to pass 6 x 1/100 = 0.06 watt seconds. Compared to a 75 watt second speedlight, that's not much. But at a few inches macro distance, you'd think it would do something. A 5 watt LED flashlight does a little, it is not black, certainly not at a few inches. And it seems to say flash mode is 2x power, and has GN 15, which means f/5 at 3 feet ought to be right. You seem to say it is not however. It has some hot shoe thingie with a cable, so I assume it is a regular flash trigger, no slave or anything to complicate it. I would try to inquire of the manufacturer support... [/QUOTE]
