This image has been produced many times by many photographers. I did notice one taken by a photographer called Maurice Welch way back in the early 1900’s for the Gallagher Views. There was a ‘challenge’ put to me then, to replicate the images that Mr Welch had taken all those years ago.
I have done so with this image. I used an f/stop of 5 with a shutter speed of 30 seconds. I also used an ND filter to allow me the 30 seconds in daylight with an ISO of 100.
