[QUOTE="WayneF, post: 176567, member: 12496"] Good luck. Magic really does not exist. :) (it is small) Indoors, you will like bounce better, when possible. That E3 menu only applies to the camera internal flash. If the camera flash door is shut, it simply does not matter what that E3 menu says. The SB-700 has its own controls, which are in play if the flash is turned on. On SB-700, this is technically TTL BL mode. Commander is always TTL BL too, FWIW. Selecting Spot Metering will be the other TTL mode (not TTL BL). But, it is also Spot metering. The camera meter you see only shows ambient, never flash. For one thing, there is no flash happening right then, but there is more - mainly because the TTL flash system has its own invisible meter. TTL is automatic flash exposure (we can control it with flash compensation though). In camera A or M mode, the flash TTL power level automation adapts to the aperture you set. Otherwise, in brighter ambient (which can be metered, like P mode), the flash TTL power level automation adapts to whatever f/stop it discovers is in use. In camera A or P mode (indoors), you should see shutter speed jump up to 1/60 second when you turn the flash on (Minimum Shutter Speed with flash, menu E2) I am assuming camera A or P mode: You must be selecting Slow Sync or Rear Curtain Sync. If selecting normal sync (no symbol in the the little sync icon box) then menu E3 will apply (Minimum Shutter Speed with flash, camera A or P modes) Slow or Rear Sync bypasses (ignores) E3, and actual metered ambient applies to shutter speed. (slow indoors) In camera M mode (good indoors), of course you can set any shutter speed you want. The visible light meter is ONLY about ambient, not flash. The meter you see is only about ambient. TTL has its own invisible metering system. Camera M mode is good (indoors), in that it only allows you to set any shutter speed you want. You still set aperture same as camera A mode, so there is zero difference to the flash. Outdoors, you have to deal with bright sun. Camera P mode knows about that, and knows about maximum shutter sync speed with flash. Whereas, if you dumbly set f/4 in bright sun, camera A mode ain't gonna work (OK, Auto FP is an option, but it is something very different). And TTL BL is at its best for fill flash in bright ambient. However, real high ISO indoors seems imprudent with flash pictures. Turn Auto ISO off. Commander is a very different animal, but Commander/Remote generally works about the same as on hot shoe (the stuff mentioned above). There are details though.
