Hello all. Thanks for this forum!


I have an issue regarding my Canon 77d exploitation the TV mode. My understanding is that if I decrease the shutter speed in TV mode, the ISO ought to modify consequently thus I will once it's a hundred.


But last night as I took images, regardless of what shutter speed I set, the ISO remained at a hundred. I took photos at varying shutter speeds and by trial and error, managed an honest shot.


Anything I ought to do in order that the ISO can adjust?


Thanks,


Maria
