This is a view out of my bedroom window looking down at the guttering near my conservatory. I was experimenting with shutter priority 1/200 ISO 1600. I have finally worked out that you need to increase the ISO to let more light in as the shutter is closing so quickly. It's simple really but my illogical mind had got blinded by science but I am now feeling more on the right track. I don't know why I hadn't worked it out before because each time I had taken one in shutter priority it had come out all dark but hopefully I've cracked it and will experiment some more
