I made a stupid mistake today.
No, I made two, one exacerbated the other.
The second, I trusted the damned LED screen on the back of my camera, which made the underexposure of the images I was taking less apparent.
So, why did I underexpose them?
Because I forgot that snow is white.
This is what I wanted the pictures to look like.

This is what I actually shot

Why the difference? Because the flowers are white.
The meter in a camera is really simple (no matter that modern meters are really sophisticated), it's trying to make the entire image fall into a range the recording medium (be it sensor, or film) can record. Really bright subject, or really dark, will fool it.
A really bright subject (like the plum blossom) will be dulled, because that's the way dealing with all that bright stuff, is handled. I was fooled by my eyes (which are more sensitive than film, mostly because the diaphragm of the eye is able to adjust to subsections of the scene), and thought the amount of background (the image is uncropped) was enough to balance out the white of the flowers.
It wasn't.
Happily, this is not as big a problem with digital cameras as it is with color film (black and white film is more forgiving of this sort of mistake than color, because the paper stocks have more variation than color paper does, but I digress), and shooting RAW makes a huge difference.
My primaring editing program (LightZone) has some handy tools, which allow me (some) to correct for this sort of mistake, at which point all I have to do is treat it as if I'd not played the fool. Some of the shadow detail is lost, but this image doesn't have a whole lot of detail in the shadows, so I got away with it.
