Having just acquired my 10 stop filter, I was itching to try it out. With the tide out as we arrived at Old Hunstanton, Norfolk, I noticed these poles in the water.
Using a pdf of a calculation table for the appropriate settings, I created the following images (while watching the tide rapidly coming in to The Wash).
1 minute 15 seconds – unfotunately, the longer exposure has highlighted that light was coming in the side of my filter holder, hence the reflection of my lens in the image. Still, at least I know when this has been corrected, it will give me the sort of images I want to be able to create.
