Hi guys,

not sure whether this is the right forum or better in the scripting area:

I would like to automatically capture three images in a row:

A Dual ISO with fixed ISO values, then another image with deactivated Dual ISO and low ISO and then the latter with the high ISO. I.e. three images with fixed aperture and exposure etc., but changed ISO and activated and then deactivated Dual ISO.

Did anyone try that out already or can give me a hint on how to script that?

Thanks a lot!

Afaik the SD card controller is the bottleneck. You should be able to find more information somewhere in this forum

I'm using the 22mm, the 18-55mm and the walimex 12mm without any problems. The shutterbug occurs on the tamron 18-200mm, but since it can be removed by loosening the lens once after turning on the camera I just do that and keep the camera turned on as long as I need it.

but now you did =)

Wow a1ex, thanks for your quick fixing.

I'm currently travelling and will try to build the stuff when I'm back. Would you be able to build a Windows executable for me beforehand or do you know someone who has the stuff ready for compilation on a windows machine?

Thanks again!

Thanks for the quick reply a1ex. This one:

is a similar shot with the same behavior after converting to DNG

I'm using Dual ISO on my EOS M quite successfully for a while and  *really* like it. However, during some shots over the weekend I encountered a banding artifact after using cr2hdr.exe and cr2hdr20bit.exe (used several different versions, the result always was the same)

Here's a crop of the image:

and here's the according debug black frame I saved.

There's a --no-stripe-fix option which sounds like maybe this is already known? But unfortunately it seems as if it doesn't work.

Could someone give me a hint where to find the source code of cr2hdr?? Is this one the newest one? (bitbucket is not working right now, so I cannot open the link):

I've some background in that field and would like to contribute if I'm able to get the stuff compiled.

Any suggestions? I actually traveled to the Anza Borrego desert staying in the desert during the night listening to coyotes and rattlesnakes to capture some night shots and would really like to rescue those pictures....

I tried ETTR but it just seems to generate random exposure times, most of the time much too long (several seconds in sunny daylight). The same happens when combined with dualiso
