So we are lucky enough to go to Antarctica next Jan... .
MikeDent - I was in South Georgia Island and Antarctica in December/January. I took two cameras, and as Mike Leggero’s linked article said (thanks PizelSta77). One camera had a 50 -200 lens and the other 24-105. I used polarizers on both cameras at first, but found that many of the shots were too blue (probably I adjusted them incorrectly). After a point, I stopped using the polarizers or maybe left one on one camera and not the other.
I never used a tripod, because there wasn’t enough time to set it up or it was too heavy to carry. As the linked article said, fur seals and crabeater seals look at you and almost pose for you. Elephant seals simply lie there like a big blob and Leopard seals in the water will approach you (one came within 25 feet of our zodiac and was checking me out, because I was close to the water and kindof handing out of the zodiac with my telephoto looking right at him – prior to that, the Leopard Seal attacked and ate an Adélie penguin, so they are dangerous.)
More to your point, I practiced with polarizers at Naples Pier before I left, so that I would have a better understanding of what happens to my pictures when the sun is at different positions. I took pictures facing North and South – I took pictures of birds and beach goers. I also tried the shots without the polarizers. Since I was learning, everything was helpful. I also practiced taking pictures across ponds with the sun at different positions…all the while reviewing the shots with my histogram. When I did post-processing, I could see that some shots needed more light.
I shot manual while there and found that I was constantly changing settings, because the clouds would roll in or the shot I wanted was not in the sun or the shot that I wanted was in the sun. Conditions can change quickly. My pics weren’t perfect, but I got the best shots of my life.
One comment that Mike Leggero made in his article (and like pmorin, I wish I had read before I left), about wishing to see whales breaching…I caught three humpback whales breaching – two small ones and one big one. I happened to be shooting whales tails and all of a sudden, the big whale came flying out of the water. I was able to get at least 12 really good shots. My point is, you don’t have time to change any settings when that happens, so getting you camera set up in anticipation helps. (I don't know if this will work, but the UHH link to those shots is "Antarctica: Breeching Humpback whales".)
One last tip. I exchanged emails with Joel Sartore about using neutral-density filters and polarizers in Antarctica. He said that he didn’t use any filters when he shot there for National Geographic. His main suggestion was not to take too many pictures, but to enjoy the scenery, because it’s not something that you will see again. I partly followed his advise, but probably too more pictures than he would have.
I could go on, but follow what CHG_Canon said – check your histogram and take test shots. Also, remember that you’ll be in a fast-moving zodiac sometimes, so your shutters speed needs to be fast enough to capture proposing penguins or a myriad of birds flying by.
ENJOY THE TRIP!!!!
