I have an image which I would like to label certain areas with some sort of a text label. I'm trying to figure out what the best way is to make the text clear. The image is color, and objects may have multiple colors to them.
A typical example might be the picture below. I would like to label the sky, the peak, perhaps the tree types, etc. I'm looking for what such labels might look like, so that they are easily readable, and as much as possible, do not distract from the image.
