    Posted: 03 January 2008 at 01:15
Hi everyone,
I recently went out for a photo afternoon with my A100 and friend of mine who has Pentax 10K; we took same photos on several occasions and seem like my A100 “burns” or misrepresent the sky.
I was shooting on “P”, ISO 100, saturation, contrast and sharpness +1. No changes on the exposure that the camera picked automatically and multi segment metering mode.
Can anyone suggest what is the best way correct this?
Thanks!!!

Meter off the sky and it won't blow out. Use a polariser to get the blue to darken, but that won't work on clouds.

If you’re trying to prevent burning and misrepresentation, perhaps you should keep saturation and contrast at 0?

Are you shooting RAW? If so in cam jpg enhancements won't contribute to the final image.

Please post an image with exif so we can make some more informed observations.

One more thing, don't use P mode. Learn to decide what aperture you want to use based on the DOF you want and the available light and then let the camera pick the shutter speed. A-mode is a great way to shoot 99% of the time and it gives you more control over the camera.

And learn to use the AEL (exposure lock) button. Set it in the menu to AEL-hold not AEL-toggle, point the camera at the sky, push and hold the AEL button with your thumb (the camera will meter and pick a shutter speed, check that it is fast enough for your focal length), focus on something, re-frame the shot, fire the shutter then let go of the AEL button. Peer at the histogram, adjust exposure compensation as necessary, rinse and repeat.

And another thing, try to shoot RAW instead of jpeg. You can decide on white balance, sharpness, saturation and all that jazz later, you can recover clipped highlights in some cases, etc, etc. Much more flexible than a couple of settings in the camera that will never be exactly correct whereas with a RAW conversion you can get the EXACT exposure and tone curves and saturation and colour and everything else even if your exposure was quite a bit wrong in-camera. Just make sure that you never over-exposure highlights... which comes down to understanding how the metering works and how to control it (AEL and metering modes like spot/centre-weighted/matrix), and how to tell when it went wrong (histogram).

hello and welcome georgesoros!
when you say burns, do you mean it darkens the sky or burns, meaning blows out the sky (white) with no detail?
we'll need to have more information, but metering on the sky and a CP will do wonders.
the a100 is very capable of skys
here's a shot of the newport coast sky @ early AM

What Polyglot said...ditto.

RAW is the answer, but one question...if you didn't like the result you were getting a misrepresentation of the sky, but had +1 Sat/Cont/Sharp...so you were telling it to lie to you to start. :)

Thanks All,
I’ll post photos from the k10d and a100 tonight (I am still at work). Yes by “burnt” I meant that the sky was too bright with lack of detail, also I was shooting at JPEG – fine mode. What Polyglot suggested makes a lot of sense I will definitely try AF lock and RAW.
Thanks to all of you again!
