Sometimes we are creatures of habit without realising it.  Another January trip to Glendalough with photography buddies.  Three of us went out with a plan of a sunrise at the lower lake in Glenalough to try out different filters. 

This photo was taken with the Canon R5ii on my Peak Design tripod with my wide angled lens set at a focal distance of 14mm.  AI set the ISO to 100 as I had the stability of the tripod and I used an aperture of f/18.  I used bulb mode and kept the shutter open for 90 seconds.  Unfortunately, I can't remember what filters I used and the file info obviously doesn't give filter information.  Note to self: bring pen and paper to take notes of filter combinations if you are experimenting with filters!!!
