So I will be going on a cruise to Alaska in June. I will be doing many excursions that will take me to some remote places such as in forests and even on top of a glacier. I want to take some awesome photos when I'm there. I am very new to photography and was wondering if anyone could give me advice on techniques or anything for nature shots and what not. Also any tips on shotting wild life such as birds or bears. My parents already have gone on a cruise to Alaska and said they saw a lot of bald eagles which i think would be amazing to get a picture of. Any help would be much appreciated. Thanks in advance. I have an Olympus E-410 DSLR and a 70-300 mm lens too.
