I need to take three pictures with different exposure values. I used vision acquisition for this. I tried using the finite acquisition but I could not find a way to set a different exposure value for different pictures. I used the single acquisition 3 times in a flat sequence with 2 seconds of gap. When I take a test picture with vision acquisition it looks fine but when I run it in the program, they are not at all the same. Sometimes two pictures are the same, sometimes it is just white and sometimes the higher exposure value is brighter than the lower one.
Help please
