Now that the iceberg has broken up and is grounded in the cove, it will remain here for a while, so I will have time to study and learn all things visual about this berg. The iceberg is smack in the middle of the front window and is in a great position compositionally and because the house is on a slight hill, my camera position is elevated to give the iceberg a sense of space within the ground plane. I'm very fortunate that I have a comfortable (heat is a good thing) room for my iceberg stake out -- I'm going to be in this room for the next couple of days and nights.
I chose the element on the right for it's shape. I concentrate, over the next few days, on this -- viewing it throughout the day from sunrise through midday, all the way through sunset and beyond. I capture all the nuances of light. -- from overcast with heavy cloud cover to sunlight breaking, illuminating the water and turning it into a sea of diamonds to magnificent sunsets with reflected light of the sky on the face of the iceberg. (Photo: The red lines you are seeing is called focus peeking, it is showing me where the lens is focused.)
My camera is a Sony RX-10 IV. It's feature set includes a Zeiss zoom lens, 24-600 mm, a superb lens. Shooting through a window is not a problem for a long telephoto lens. You can actually shoot through a window screen with no problem. You have to make sure that your auto focus is disengaged and you set focus manually. Lock the focus on the subject and your focus will always be right on so long as you or the subject doesn't move.
