LOL! Smooch! ;-) > Very true. How do I find 5% below the saturation limit of my sensor when the > histogram only tells me the values on the JPEG, not on the sensor? I'll note > that your M9 gives the sensor values, not the jpeg values. The M9 histogram and data processing is actually very sophisticated. When you go to info mode on a zoomed in section of a photo, it allows you to examine just that section in the histogram. Subtle, simple, yet very sophisticated. I don't know whether it is working on the raw or the JPEG data yet, haven't had enough time to learn all that. But it's metering, fundamentally simple as it is (APAE or manual only, strongly center weighted) simply delivers the right results for me in nearly all cases so I haven't even bothered looking at the histogram all that much yet. The exposure is right on the money when I download it and open up the files in Lightroom. > In the time available for action shots.

Sure. How many dozen people would find this of value, and are the hundreds of thousands of dollars in development time and testing worth the investment? > Do you check your results with the histogram, or just decide that you're good > to go? When the lighting is really wretched or the scene very difficult, I do. Or I just bracket and don't worry about it, work with what worked well when it's time to render. I don't expect every shot to work out perfectly ... If 10% of what I shoot is worth doing finish work on, I'm good with that. >> I don't know of any automation system >> that can do this pre-exposure ... they simply don't have enough data >> to work with like your eye and mind does. > > Exactly, that is why I want a mode that will take a test shot, or test shots, > analyze the data post exposure and report on the ideal exposure based on the > scene, and your tolerance for blown out highlights.

You'd have loved an Olympus OM-4Ti. Multispot metering system built into the camera. I almost bought one a few months ago purely for the nostalgia of it. :-) -- Godfrey godfreydigiorgi.posterous.com -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
