re: Distorted DNG

Also tried saving images as DNG, it seems that its not calibrated for the S80's 8mp IMHO, distorted with pink banding.  I'll be saving in raw for the meantime, included the Dng4Ps2 binaries in my SD card so i could run it anywhere :P

Thanks for the port to the s80! I've been having a great time learning my way around the CHDK.

One problem I'm running into is setting my s80 to save images as dngs. The dngs are heavily distorted, appearing mostly as large swaths of magenta colored diagonals.

Has this feature not been implemented yet for the s80 or is there some other possible problem?

Thanks!

When I override the F-stop to F16, i'm getting a smudge like artifact in the lower right of the image. In F8 no artifact or distortions are found.

Can anyone confirm this?

This could be dust inside your camera. In the DSLR world it's well known that the smaller the aperture the more visible any dust on your sensor will be. It is not unknown to also get dust inside the "sealed" bodies of PowerShots.

In that case it won't exist on anyone else's camera.

Thanks for the info and installer rcperez!

As DavidB said, I had a very small smudge on the lens that wasn't visible until I set the camera to an aperture above F8. Cleaning the lens off with a q-tip removed the problem. On a related note, I'm not sure the camera's aperture is "really" being set to F16. Can anyone recommend a way to test this?

Thanks for the info guys :)

I tried shooting a light bulb in AV bracketing +1EV starting from F8, and after looking at the histogram noticeable difference were found after 4 exposures, thus F11, all the following shots where just the same, minute changes.

As for the save as DNG, i think the header is also incorrect, i extracted raw from the DNG file and converted it with DNG2PS, picture was not distorted but with messy colors and noisy image (might be due to a few missed data from extraction)

USB remote - also tried making a remote, found that it could be triggered from sleep to shoot with just 3V coming from a button cell.

I'm not really sure how fast my shutter goes, already tried TV bracketing which i think went all the way up to 33,000, but still am unsure.

And since there's no humming bird around for miles, will a flying wasp captured on hand do? (actually was planning on capturing a 550FPS BB gun, but a wasp suddenly reared it's ugly head.)

Image is a bit out of focus, because I was just approximating the distance (plus fleeing at the same time). I did manage to stop the flapping of the wings though, even when tracking the wasp on hand.

The flash is probably faster than whatever the real shutter speed is.

Don't forget what the H stands for.

Also flash was set at its minimum, shadow was from natural lighting.  Though final image was really dark.

its a far cry from this ...
