[QUOTE="WayneF, post: 252828, member: 12496"] Low camera battery could cause problems, but I'd guess probably not with problems with the flash. You have a camera menu Setup - Battery Info that will give more precise state of charge. You CANNOT use flash TTL mode with radio triggers. It probably flashes, but at undetermined power level. Flash must be in Manual mode M. If you want TTL mode, then give up the radio triggers, use the D7000 Commander, and set Remote Mode on SB-800. See [url]http://www.scantips.com/lights/awl.html[/url] Issue 1 - black. This sounds like the flash is not firing, possibly due to the radio triggers. Did it flash? Take a similar picture with the flash turned off, see how black it is (oops, that is assuming camera M mode. If camera A or P mode, automation will just crank it back up with a very slow shutter speed). If it was camera Manual mode, and ISO 100 and say about f/8 at about 1/100 second, normal room ambient ought to be about black (which is normal with no flash, due to severe underexposure without flash). It is probably a good idea to put the flash on the hot shoe (excluding the radio triggers) while figuring out if it is a triggering problem, or something else. Issue 2 - flash exposure should not vary, but it will if you have some form of bracketing left on from last time. If the word "Bracketing" rings a bell, verify you did reset it off. It does sound like the first thing is to charge the camera battery. See the camera menu Setup - Battery Info. [/QUOTE]
