In 1.1, the A590is subject distance override at infinity is 52855, not 65535.  Why is that?
Hi, I don't have access to a590, could you test this: http://chdk.setepontos.com/index.php?topic=2509.msg79886#msg79886   ?

Mode 32791 is an unnamed mode with fish icon, but different than when the camera is in the aquarium mode.

It is the under water icon in D10.  What if you try to take a photo using it?

Thanks, but I found that the min and max subject distance were specified in a change to camera.h a while back, so I'm going to assume that was done correctly.  Since I had always seen 65535 in earlier versions, I just wanted to be sure it wasn't a bug of some kind.

@nafraf,
The A590IS has a tendency to overexpose video.
I think CAM_EV_IN_VIDEO is useful to correct for video overexposure and shouldn't be removed.
It is good to make videos of the moon, stars (with a telescope)... it helps to control overexposure well.

Perhaps the UI control should be modify to indicate that it is only to control video overexposure.

Hi, I have not used that feature. I removed it because blackhole reported that it was not working well in this post.
A modification to UI would affect all cameras, what is your suggestion?

You may also want to take a look at this bug.
If you set:
CHDK Settings->OSD Settings->Miscellaneous Values->Show Misc Values [Shoot]
it behaves as:
CHDK Settings->OSD Settings->Miscellaneous Values->Show Misc Values [Always]
I'll check this, it seems to be a bug.

@nafraf,
My suggestion is that since CAM_EV_IN_VIDEO is useful to control video overexposure and it doesn't crash nor affect the A590is, it is better to leave it there.

Nice to know that you are working on the OSD bug.

A590 in video mode uses evaluative metering mode and you can not change it.
 If you recording stars, 99.9 percent of the scene is black, because the stars  as a point sources of light are overexposed. CAM_EV_IN_VIDEO does not respond at dark scenes, in bright scenes gives you just two EV steps what in overexposed scene usually not enough, if at all responds. Enabling "Fast EV Switch" in "Extra Photo Operations" menu gives you exactly what you need in this case.
Another disadvantage is that the CAM_EV_IN_VIDEO you can adjust only during recording.
Fast EV Switch can be adjusted before recording and during recording

>CAM_EV_IN_VIDEO does not respond at dark scenes

It is not for dark scenes, it is for too bright scenes.

It is useful for overexpose video scenes
in general. And it is fast and easy to access by just pressing
the +/- key during video recording.
