Sometimes I can, others I cannot. I assume this is an easy answer but I'm very new and still a little lost. Is there settings that turn the viewfinder off? Should I always be able to see through it?
Does a D3200 have an eye-piece shutter that you use to close the viewfinder for long exposures? Might he/she have flicked the lever and not realize it?
What camera do you have? Has this inability to look thru the viewfinder just happen or has it always been this way?
What is mirror up mode?
