    Snow and sunshine

    It is a nice experience to walk the same path under changing light conditions at daily distance. In winter there is not much botanically happening, only the snow can be more or less – or the fog. The possibilities of imaging with a camera essentially change with the extent of the available light. A sunny day shows a maximum of available light.

    Does sunlight make a picture atmospheric ? With cloudy skies or even some fog, the conditions for background and foreground change substantially and pictures without sunlight can be be very varied and gain a special depth of expression.

    The above image shows: shadows during a day with a blue sky are blue, too.

    The detection of expressive light situations without a tripod and without HDR technology requires a limited amount of light that the sensor can still process with out blown-out lights or drown depths.

    Composite of a sunflower: X-ray, light and Hα

    In a digital world we can combine different digital sources. This photo of a sunflower is a composit of its X-ray, its photo on a lightbox and monchromatic sunlight at a wavelength of 635nm (Hα light).

    In fact: this is an example of an impossible thing. But you may be able to feel the warmth of a sunbeam emerging of the core of the sunflower. And the petals act as prominences.
