Actually the sun was to my left. The TPE plot of the light can be seen here and the large red dot is roughly where I would have been standing.
I understand all about shooting into the sun in a snow scene (having done it many times).
The sun is just about dead ahead in this shot.
Again - the red dot would have been where I was shooting from and the focal area of the shot is represented by the pin.
Sorry, no salmon in these rivers - way too far away from the ocean. Trout, perch and bass are the types of fish you will find in this river.
