Hello, I am visiting this December the High Arctic and there will be "polar nights" - no light only night which is extremely blue. ( I am Not speaking about the northern lights). So I was wondering if any of you have already experienced those conditions - what advices will you give me? Are there any filters to reduce/ cut blue light? What about any filters to emphasis even more that blue light? i would like to do few experiments why in those conditions so I will really appreciate any help and advice!
