Your idea to set up duplicate camera descriptions is quite good. I tried it. Each Twain device needs a '.ds' file in the windows\twain_32 directory. Leica provides a software TWAIN camera simulator that always returns the same image. I made a copy of this '.ds' and can see two data sources in a sample TWAIN application. Unfortunately they have exactly the same name (supplied by the .ds) and are therefore difficult to distinguish. And microManager currently only displays one of them. microManager could be improved to allow selection of multiple 'copies' of the same .ds TWAIN driver.

we also have this camera, and we have the same problem. Except Gamma and exposure time, the other parameters such as binning or image size need to be controlled by the Leica software.
What makes it worse is that MM and Leica software can NOT run concurrently, so changing these parameters is a bit painful.
I was wondering whether a number of such "camera descriptions" could be defined to appear as different cameras so that inside MM we could have the option to select a different "camera" corresponding to different presets of binning for the 350.
Just an idea for Karl

I haven't got the Leica camera anymore, however, I believe if you launch the Leica proprietary application, you will be able to modify the camera image parameters such as image compression. Such vendor-specific settings are not generally accesssible through the TWAIN interface. Currently μManager only supports reading uncompressed images from the camera.
We are trying to use micromanager with our leica camera DC350F. We have an error messsage : "error 22", unsupported image compression.
We did not managed to fix this.
Thank you for your help
