i was in Vik around 12 the midnight and i was waiting for some light from the midnight sun ,after an hour the clouds right across open up for few minutes ,and i was able to get some light in the clouds on top of the church .I used an 6ND filter a 3ND and the 0.9 ,i decided not to use the Big Stopper because it produce a blue cast and it wouldnt look good in this photo.
