Hi guys & dolls, Hey, I am going on an Alaskan Cruise the end of August with family. I have switched my camera to auto ISO as if it is sunny I want to use my polarizer....and sometimes not. Do any of you use auto ISO, if not why & if so why? I figured with the time frames we are in ports, clouds, rain etc it would be a good thing. Also if any of you have been on a cruise, are tri pods good or no. I have researched & researched & am bringing my tripod for long shore days, but have heard not so good on ship.
