Hello. I am trying to set up a new 50R. I want the histogram to be displayed on the LCD screen and in the viewfinder before I take the shot, so that I can adjust exposure as necessary. I have gone into "Display Custom Settings" under Screen Settings and ticked the appropriate box, but all that happens is that the histogram flashes up for maybe half a second when I turn on the camera, then disappears. Has anyone any thoughts? Thank you!
