Hi !

I am using pointgreycameradriver to use and trigger a camera (i am not setting the shutter speed in the parameters.) I know that some information can be embedded in the image (shutter is one of them.)

The imageexposuremsgs/ExposureSequence msgs should contain these information and should be published in /camera/exposure_sequence topic. However, when I print the output of this topic, it seems that there is noting published here !

Is there any way to get these data then ?

Thank you
