I am not sure where to ask this question but I will give it a blast here and see if anyone can help...
I have been playing around with some focus stacking today and have got to grips with the software mechanics but am having a problem getting my flash to fire off camera using my Cactus trigger when shooting tethered through the EOS utility program.
I can shoot tethered no problem, I can get the flash to fire whilst not tethered using the on camera shutter button and I can get the flash to fire whilst using a remote trigger but whilst tethered I get no light 
Hopefully that makes sense and some one has an answer?
Thanks in advance
Brian
