Just because it’s raining or foggy, there is no need not to go outside and get snapping. Yes a low auburn sun may be considered the perfect light for outdoor photography but if you live in a country where it drizzles more than it is dry your only option is to get out there and make the best of what you have to work with.
Thunderclouds can enthuse drama and tension into a shot, so meter on the clouds and set a narrow aperture to capture as much detail as possible, but don’t forget to include some foreground interest.
Even if it is pouring with rain you can still use this as a photo opportunity. For best results use a tripod, self timer and dial in a long exposure or use a narrow aperture. The resulting image should show the slow fall of the rain and convert to black and white for a more dramatic images. Duck under a protected covering like a porch or tree for some shelter.
