Hello Kevin, That sounds a bit odd. Since the camera is not involved at all in the exposure setting (I assume). When I use studio flash (Alien Bees) and meter with my Gossen Luna Pro Digital F, the exposures are just about right. I would think that perhaps your meter is calibrated just a bit off. At least, if you set the *istD on full manual exposure and then metered the scene and set the camera, the exposure value should be about right. I would expect the same behavior if you set manually for an outdoor shot with no flash and with a separate meter.
If you had a film camera that you manually set based on some external meter reading and the exposure was off, you would first suspect the meter accuracy. Second, perhaps the shutter speeds of the camera and third, the lens aperture closing in time. Seems to me that your problem is totally unrelated to TTL flash metering on the body. Care to enlighten us a bit on the details of what you are doing? Are you using studio strobes that use your TTL ciruitry in the camera? -- Best regards, Bruce Saturday, January 31, 2004, 2:14:02 PM, you wrote: KW> This one time, at band camp, Frits Wüthrich <[EMAIL PROTECTED]> wrote: >> Try shooting at ISO 400 when using a flash.
