I am new to film photography, having adopted my Mum's old Nikon FM2. I've successfully taken photos on this camera recently, but the last roll I received back was totally milky.
I don't know if I had the wrong ISO setting on the camera the whole time - the film was a Kodak T-MAX 400 black and white film - or if things went awry in the processing stage (I took them into a print studio).
I've attached a couple photos for reference, and a picture of one of the associated negatives. I've just loaded the same exact film into my camera again, and I really don't want to waste it. Any advice would be appreciated!
