Originally posted by Workingdog Go to 1/20 sec, F3.5, ISO 500, bar still flashing. Not the shutter speed, just the bar. I know what flashing numbers mean but not flashing bar.
Furthermore if I try to rotate the dial to increase the shutter speed back to 1/25 it will not let me. Why, why, why?
Hyperprogram on the K10D/K20D basically will not "agree" to an exposure setting that isn't "right." Now, it will
give you such a setting initially if you ask it. When you hit the green button, there seems to be some minimum shutter speed that the camera uses regardless of whether that minimum setting works or not. So you can take the camera into a dark room and hit the green button and the camera will give you an exposure, using the highest ISO available (if you're set to auto-ISO) + the widest aperture available for the lens + some minimum (i.e. slowest) shutter speed, but it won't apparently ever give you a shutter speed of, say, 3 seconds, even if that would be the right speed.
Now, if the settings suggested when you hit the green button aren't going to produce a properly exposed picture, according to the camera's calculations, then you'll also see the flash symbol flashing. This is underneath the aperture value. I don't know what you mean by some "bar" flashing. I don't see any flashing bars on my K10D. The flash symbol blinks on and off to, um, suggest that you pop-up the flash and use it.
Finally, if the initial suggestion re exposure with a shutter speed of say 1/30th sec is still underexposed, then when you slow down the shutter by turning it to 1/20th sec, you can't get back because, as I said earlier, the camera won't let you dial in a bad exposure. In other words, moving from 1/30th sec to 1/20th sec is a step in the right direction and the camera won't let you step back, since that would make the exposure WORSE, not better.
I am increasingly fond of P mode on the K10D/K20D and have started using it a fair bit. I am using it only because it's hyperprogram--that is, because it's such a wonderfully smart feature and because I still feel as if I'm in control. However, it works best when light is good and even; and it doesn't work very well when it's not. I just came back from a vacation in the mountains of southwest Texas (Big Bend National Park). I had to deal with a number of challenging exposures--bright skies, dark mountains in the distance, and middle-zone desert landscapes in the foreground. I often switched from P to M because doing so was easier than getting the right exposure using Ev adjustments.
