We have been spending considerable amount of time uploading my pictures on Fotolia, one of the main websites for stock photography.
It is a lot of work to get them on there, but the occasional reward makes it a lot of fun. You can find my ever-growing portfolio here.
I currently have almost 3000 pictures online, and sold more than 350 of them, which makes me mildly proud. It is never gonna make me rich (and you definitely do not want to calculate how very little we earn for an hour of work!), but selling 350 pictures is tremendously more than I would have ever thought possible.
It is funny to see what kind of pictures sell the easiest. This posts shows some of the bestsellers in my portfolio, and it is immediately clear that exotic travel destinations do very well.
Landscapes, but also famous cityviews are thus high on the list, but they contrast sharply with the dull pictures that seem to get at least as much attention: car parks, traffic signs, spoons, the more ‘normal’ it is, the easier it sells.
But surprisingly, even my work seems to sell, as illustrated by this detail of stress measurements on our university campus.
For someone who likes to make pictures as an extra to his main job in ecological research, selling some pictures through Fotolia is a nice reward. I will never be able to resist the urge to make pictures anyway, so better make the most of it!
