I've recently commenced the second pass of files from the Norwegian 'post-celebration' trip with Erik. Once in a while one gets a true surprise when the captures are processed. This photo is an illustration to that effect. When we were in the field, lots of areas appeared not to have strong autumn colours at all, but later evidence exists to show the opposite.
The valley of Grimsdalen in the central mountain range of southern Norway has a varied topography and hence also diversified vegetation and numerous glacio-fluvial features from the last ice Age. All are potential candidates for creating interesting images in infrared.
Here is a stitched panorama from the western part of the valley, shot with a broad-spectrum Nikon D600 and the fabulous (and unfortunately, also very elusive and expensive) 200-400 mm f/4 Nikkor ED zoom lens. The diversification and range of autumn colours in the landscape is well-nigh unbelievable. But the camera never lies.
