Clematis

Eeks I just had a HUGE blonde moment so I only took a couple of shots just in case anyone saw what I did. I stepped outside a little while ago to take a few shots of my clematis which is in full bloom - but I can't get the camera to do anything and the viewfinder was pitch black I spent ages adjusting this setting, that setting and back again!! What was worng I had left the lens cap on *hangs head in shame*
