I took this image of Monte Rosa hut while hiking in the Swiss alps. The hut id close to the resort town of Zermatt and one of the most modern moutain huts in Switzerland. The photo is a time blend of early blue hour (base image) with mit blue hour (lights). I used a tripod, my Canon 5d mark III, and a Zeiss 21mm f/2.8 lens at f/7.1, iso 100, 1 sec for base exposure. Post processing was done in Lightroom (lens correction, chromatic aberration correction) and Photoshop for blending the base image with the image for the hut lights using lighten blend mode and masking. Noise reduction was done using Nik collection denoise. Sharpening was done using a high pass filter.
