I have just been working on some images I shot yesterday (27th December 2018) in Cleethorpes, Lincolnshire with my very trusty old Olympus Pen Lite EPL-3. I used the widest lens setting and an ISO of 400. Images were adjusted in Photoshop for levels and then given an HDR treatment. Personally, the best time at the seaside is during winter. I live about seven miles form here and even closer to other beaches in Lincolnshire. It is a great place to photograph.
