Hi there guys and gals! I am fortunate enough to be heading to Alaska for a 7 day cruise in about 3 weeks and need some advice on shooting landscapes both from a cruise ship and from a moving train. We are going to take the White Pass railroad train trip excursion and having never shot from a moving platform I need some advice on camera settings and lens selection. I have a 17-40L, and a 28-75 to choose from for my landscape shots and a 100-400L for my wildlife close-ups. Being a portrait kind of guy I am unsure of how to set up my 5D mkiii to shoot from something that is moving down the tracks. I am guessing I will need a faster shutter speed than you would normally use for scenery shots and perhaps a higher aperture number to get more depth of field? Being a total noob to this type opt photography I am looking for any and all info to help me get some memorable shots. I never shoot in auto mode so camera settings are not a problem for me...just need some suggestions. I will also be shooting from the balcony of our cruise ship. Thanks for any and all input!
