Does anyone have any good tips for manual photography on an ice sheet? I've googled around a bit, but most "12 Tips for Photographing Snow" type webpages are severely lacking in depth. Many of these lists include tips like, "wear warm clothes." Most snow photography tips seem geared toward mountain landscapes where photos contain a fair amount of color (rock outcrops, trees, creeks) throughout.
I find that on ice sheets my surroundings are quite stunning when I'm there, but the lack of color or contrast makes it difficult to capture with a camera. What tricks do you have and when do you use them? The two tricks I've found:
1. Always turn off the automatic white balance to prevent snow from looking gray, and
2. Use a polarizing lens to increase contrast at the horizon between snow and sky.
What else should I be doing?
