Originally posted by Rondec Digital cameras try to preserve highlights. This is as it should be. It is relatively easy to bring up the shadows, but to bring back blow highlights is virtually impossible. The camera here did expose correctly. The problem that I have with older Pentax cameras (K7 excluded) is that they tend to be fooled by small, bright objects, that I would rather have them ignore.
Truthfully, the issue is not the overall exposure, it is the exposure in the shadows, which it is fairly easy to fix in post processing (as Jeff did above). What I think you are really looking for is an HDR-like image that has detail in both the sky and the mountains.
Interesting thoughts in this thread. I wonder if Pentax's metering is just a little more agressive in terms of preserving mid-tone uniformity than Canon/Nikon.
I have to say I've noticed that some of the shots I've taken have been . . . aggressively metered.
I need to start shooting raw with this camera (but need bigger HDs for my computer and backup server first!), because I think I'm losing too much detail in the shadows by using JPG.
One of the things that bothered me with a high-contrast shot that I took last week was how little detail remained in the "shadows" of the image.
Shot 1: This one was correctly metered. I'm fairly happy with how this shot came out; This is just to show you what a the lighting conditions were and how it more correctly metered. Even here it tended toward the dark side. That plastic tank is bright white and it actually looks brighter than the PVC nozzle in reality. After reading this thread, I know I should've AE-Locked after metering on the bushes or something, and then focused on the spreader and shot it. Or I could've used fill flash. But this shot is still usable, I'm happy with this shot. In fact, I guess it's better that I have the detail in the tank, and if I'd wanted the tank white I could've PP'd it.
Shot 2: Closeup of the handle of the spreader. Granted, this is a milled stainless steel piece reflecting the bright florida sunshine. So I get that it metered way down. However, for two reasons I think it took it too far. Nubmer one, that piece of metal is, in reality, very bright. The K-X underexposed even the piece of metal to the point that it looks dark. Now, granted, it preserved every detail of the piece so well that the tiny bevels and milling almost make the image look like it's a ghosted multi-exposure. Secondly, look at the black areas in the grass. When I tried to bring up the shadows in the grass to make the shot look less foreboding, the shadows were blown out to black and I couldn't touch the shadows control, because it was causing black banding in the grass. This shot was done with the Shadow Compensation in-camera set on low.
And here's the kicker. That shot looked FINE on the LCD for review.
It's not a big issue, Pentax just makes you use your brain a bit to get the best pictures.
By comparison, here's a high-contrast pic I took in December with my Rebel XS. It's a good example of no-brainer metering. It's also an example of a very uninteresting shot.
This was a bright clear day in DC and the face of the building was very bright. It was shot in JPG, but you can still see plenty of detail in the shaded face of the building. 50mm, F25, 1/120, ISO800.
Here's another Canon shot:
On this one, the sun was behind the building (I was standing 90 degrees clockwise from the previous shot I posted), and the face of the building was in shadow. The only way to take this shot was to either bracket it (and it was FA-REEZING. At 25 degrees and 20mph wind, I was not busting out the tripod), or blow the highlights. But without having to meter a frame that was entirely shadow, then shoot, the camera chose to preserve detail in the shadows and blow the highlights.
I think it's about the camera's brain, and what it's priority is . . . shadows or highlights.
