In photographic theory, we are normally taught to avoid harsh light, that casts hard shadows and creates washed out colours; essentially, avoid the middle of the day, especially if it’s not cloudy. It makes sense, however it is all relative to the purpose. Sure, if you want to shoot portraits outside, either create your own light or avoid such conditions. Also, if you want to shoot landscapes, better stick to early morning or sunset, where light has warm colours and creates all kinds of subtle transitions in the clouds and on the ground.

However, if you want to take pictures in the city, harsh midday light with hard shadows and reflections in the glass might be exactly what you want. I actually prefer the harsh but almost horizontal light before the sunset, almost at the golden hour, because it’s easy to find motives where the light shines through leaves or grass or whatever, and makes everything glow as if the light comes from within.

It doesn’t work that well when the light is vertical, so high noon is to be avoided still, but there’s still that period when the sun is low enough that it passes through flowers and leaves almost horizontally, but strong enough to create light that would conventionally be deemed too harsh for photography. However, if you use sun the way you would normally use a lightbox, to pass light through almost-transparent things in order to make them glow, that would work just fine.

As for the shadows, sometimes I actually want them, and the light that makes them is the actual subject of my photo, and the thing formally chosen as a motive is chosen merely to showcase it, and has no particular meaning as such. The fact that I take pictures of flowers or pine cones or leaves doesn’t mean that I particularly care for them; they are merely elements I use to portray atmosphere and feeling.

Sure, light sometimes casts harsh shadows, and for some types of photography you want to avoid that; portraits, for instance. You don’t want shadows on your model’s face. However, if light and atmosphere are the subject matter, sometimes shadows are what you actually want, and they are what makes the picture.

So, there might be no such thing as bad light; only bad light for certain things. Some photographers consider blue sky and a clear day terrible conditions for landscape photography, because one tends to create boring “postcards” in such conditions, instead of the mood and character you get from the clouds and so on. I kind of agree, but to me it only means you need to get more creative and dismiss the easy shots everyone would get first; take those pictures just to get them out of your system and delete them later, but once you get past the obvious, you might get all kinds of ideas about things to shoot in harsh light and a washed-out hazy blue sky.
