I've done some long exposures at night with steel wool photography, but today I wanted to do a long exposure of a waterfall I saw. The camera (Nikon D3000) said the subject was too bright, and after taking the photo it was completely white, you couldn't see anything. I haven't changed anything in the settings but making the shutter speed a little longer (it was set for 15sec from my last project). How can I fix this?
Thanks!
