I know the dslr is giving reflected but my phone's lightmeter agrees with the dslr and the histogram reading matches what I'd expect to see from the reading. But that's the digital side of things and we shouldn't talk of such things in here
When I meter, for example in an indoor portrait session I will take mulitple readings from the top, front, sides and rear (usually around six seperate meter readings to check the light falloff is right and set my camera for the highlights. I like to know how much falloff I have around my models to control my light better.
Doing the same thing in an outdoor session in the ambient metering mode on the 358 I get erratic readings similar to the ones I posted above.
Say I'm using my OM2 and you have the +- symbols light up (reflected). When using my phone light meter they match up nicely when I set the OM2 to the settings on my phone. However on the Sekonic it will either register above or below (over and under exposing). That's ok when I have a relfected meter to fall back on in camera to ballpark my figures but with my C330 that doesn't have any metering I have to rely on external metering.
I am thinking actually after explaining this, that I do have a problem with my sekonic. Thanks. I hope that this info is useful to someone else and I haven't just hijacked the Op's thread for nothing. Sorry about that by the way.
