On our last trip to Nepal, we decided to trek Mt. Annapurna up to the first base camp located at 5000m above sea level. The trek itself lasted for 7 days and the shots taken on this trip represented a real challenge due to the harsh weather conditions and low temperatures reaching up to -25 degrees Celcius during night time. Combined with a limited number of 3 spear batteries I realized that I could not afford to lose any minute of battery but despite the odds, I managed to create this video.
