If you like the photography in the wild (outdoor), we are often confronted by unfriendly weather. Partly for example. But do not let your preoccupation with photographing clouds blocking. Here are some objects that are even better in the pictures in cloudy weather.
People / Portrait & Animal. Produces a flat overcast lighting and gentle, as if you have a giant soft box up there. Light during overcast produce a better facial images. When photographing faces in the sun you will trouble controlling the contrast of dark shadows and light that is too loud (usually under the eyes and nose and the neck).
The trees. Try photographing lush trees during the heat of the sun, you will find that too harsh contrast between the sky and leaves. When cloudy this contrast will be reduced drastically so that the overall result will be great photo.
Waterfall & River. Waterfalls and streams would be much nicer in the photos when clouds arrive. We will more easily create Cotton effects that make the water look like clumps of cotton are soft, even the darker the gray the more subtle “cotton” is obtained.
The sky. Chance of making the sky seems more dramatic because there are gradations between dark and light.
