canon eos 6d: dark images

[Skye]

Hi,

I was shooting in manual with my camera (canon eos 6d) and a friend was shooting the same subject at the same time on the same settings as me (iso, shutter speed and aperture), but her images appeared much brighter on her viewfinder - any ideas why?

Thank you so much! Really appreciate your help!

Yes, one of these was not the same!

When you look through the viewfinder, you see the image through the widest aperture of which the lens is capable; and the wider the aperture, the brighter the image. If your friend was using a lens with a wider maximum aperture, her images would appear brighter. The settings at which the picture will actually be taken have no effect on this.
