[QUOTE="J-see, post: 369369, member: 31330"] Thanks, I'll check that out. In the past light metering as is was needed because photography was a chemical process. Some uniformity was required because of that. This 18% grey uniformity was a way to get around the problem of exposure time needed for that chemical process to occur without changing the time usage of the cam to something relative. But these days it is a digital conversion done by each camera itself. As such, light-metering of the past seems very outdated. If they still use it, there must be a good reason for that. Either there's a problem they can't get around without this uniformity or someone's very very lazy. ;) Edit: I'm trying to search an explanation why this out-dated method is still used but alas, there's next to nothing to be found. I however came across a pretty interesting article while doing so: [url=http://www.luminous-landscape.com/tutorials/optimizing_exposure.shtml]Optimizing Exposure[/url] Some might have read it.
