Decided to try some REALLY long exposures today down in Scarborough using, not one, but two ND filters. One on the end of the lens, and one in the canon EF – RF drop in filter adapter (you need an adapter if you are using an EF lens on a Canon Mirrorless camera such as the R5 that I was using). Exposure was around 180 secs at f/8 ISO 160. I was using a Sigma 24 – 105 F/4 Art lens on my Canon R5. 

I decided that black and white suited the effect I was looking for. Well that’s my story anyway.
