Winter stratus

Frost covers birch catkins at Ministik Lake Sanctuary near Edmonton, Alberta

Branches and catkins against a flat winter sky

In central Alberta the cold snap is over, and a prolonged case of the "winter-stratus" has set in—stratus clouds, that is. These are low, featureless clouds and in winter, when there isn't much moisture, they are generally light grey to nearly white. Sometimes, like yesterday afternoon, they'll lift a little to where you might call them altostratus, and you're more likely to catch a little break for the sun to peak through. These are probably the most common clouds (stratus and altostratus) over Edmonton during the winter when there's not enough solar energy to build a decent cumulus cloud. (I think I may be letting the cloud-watcher nerd in me show a little here).

Photographically speaking, stratus clouds make the light perfectly flat and even, which can be both a curse and a blessing. Generally, the contrast of side light and shadows makes for more dramatic images than the flat light under a stratus ceiling, but I find that sometimes detail-oriented compositions benefit from the "huge softbox in the sky" effect. I enjoy the challenge of finding these photographs on days that would normally be considered photographic busts.
