One day the shot was blown out BIG TIME and today I have 8 in a row just like this one here. Cloudy day but still many oof shots. I think I was using centerweighted again, I should stay away from that one.
ISO 400 f/3.2 1/8000 +1/3 EC AV mode centerweighted. Hmmmm how in the hell could this thing jump like that and it's the second time I had a problem while metering. The other time it was a very bright day and the image was wayyyyyyyyyyyyy overexposed. I wonder if the problem is only that secondary mirror. Anyone?
Just noticed the shot right before these and the one right after I was at ISO 500 1/1250 and 1/800. Like I said it was a very cloudy day and a lot of time my ss was around 1/800.
Darn gremlins LOL
Someone here posted that the MKIII felt drunk to him and it doesn't feel right at times when getting shots and other times it feels great, almost like hitting a golf ball perfectly.........well that's something I only did a few times LOL
That's very wrong lookin'.
Even if you spot metered off that girl's white shirt, the image should not have come so grossly underexposed (by probably one stop or more).
PK I posted another one on here a few weeks ago and I was shooting around 1/2000 and I think it dropped it to 1/160 or something like that and totally blew it out and I was using centerweighted again. I need to stay in evaluative while outdoors until I get the shipping label and ship this thing back.
John, I believe the problem is computational, i.e., firmware.
The reason for saying that is in my understanding that all metering modes use the very same area sensors.....just the individual sensor signals are processed differently.
I'd call this a camera defect and have them Canon boys fix it.
John, this happens from time to time on my Mark 3 as well. I was shooting a beach race, quads and stuff, last weekend, and I would get bursts of 6 or 7, every so often 1 came out very similar to yours, grossly overexposed or underexposed. I was using Partial metering with my usual +1/3 EC. Looking around the frame there was nothing it that could have caused such a dramatic change. I guess it ranks fairly low on my importance scale due to the AF problem. Perhaps this new sub assembly mirror thingy will fix this as well. Lets hope!
I have had some very erratic metering and intended to ask them to fix it when the camera went in for the sub-mirror. Nothing this bad but substantial, problematic and totally unpredictable.
Ok, I've never used the 1DmkIII, but from the shot parameters you describe, it could be explainable...
Centre weighted average would put most of the metering on the girls white collar. The camera will then try to reproduce that tone as an 18% gray tone, which is what you've got in the final result. Even with +1/3 ev, the camera will be fooled.
Did each shot have the exact same composition with the white area in the exact middle of frame?
