I absolutely love long exposure photography! Such a challenging yet satisfying way to shoot. Also, very creative and interesting types of photos. This technique can definitely produce some beautiful art.
I have started using magnetic round filters which I find very convenient for composing and focusing. I found a small company in England where I live who sell magnetic conversions for round filters. I found this a cost saving as I already had some round screw ND filters. I sometimes combine long exposures with panoramas. That can easily run into a couple of hours 😀 Thank you for a very interesting video.
