UV Flowers

Last weekend I spent some time on M's balcony taking pictures of flowers. I had bought a while back some UV-pass filter blocking all wavelengths besides UV just for that purpose as some flowers are supposed to show patterns invisible to the naked eye. I ended up spending a good 2 hours going on the balcony before finding some that were showing something different in UV but in the mean time I got quite a few other nice flower pictures in visible light and IR as well.

Petunias (UV) note the black stripes radiating from the center

Petunias (visible) just white

Orchis (visile light)
