Having finally figured out how to wiki images, I've posted images and
brief comments on a few more bulbs:
Homeria collina (Moraea c. these days but we still have a Homeria
page.)
Oxalis 'Ione Hecker'
Crocus kotschyanus
These are accessible from the relevant wiki pages in the ordinary way.
The pictures aren't technically the greatest, but I've made an effort
to provide images that fairly faithfully represent the true colors of
these plants' flowers.
Some comments on digital photography (using a cheap little Sony
camera):
1. Always use a tripod. Except in bright sun, exposure times are long
enough to make shake a problem.
2. Lowering the exposure value (EV) by 1.7 or 2.0 units (half a stop
to a full stop), immensely improves pictures taken in full sun and
gets rid of the overexposed glare one gets on petals. I find that
adjusting the gamma value during post-processing helps lighten up
areas that may be too dark.
3. Lowering the camera's contrast and/or saturation also helps in
some cases. It appears that digital cameras, like film cameras,
converts all bright reds into a single undifferentiated fire-engine
red otherwise.
