Nancy, et al:
A few tips to improve color:
1. Shoot in raw format (or raw + JPEG.) This will preserve more data to
permit adjustment of color balance after the fact.

2. As soon as possible after the quarry escapes, take a photo of a "gray
card" (see below), or pure white paper, in the same location as the
bird. Make sure to orient the gray card to catch the light in a way
similar to the bird. Because the gray card has known color, your photo
software can use that photo to compensate for the color of the incident
light.

While this will not give perfect color, it can help quite a bit. I
suggest practicing a bit on flowers (or other colorful objects). Even if
you're not comfortable using photo software to make adjustments, if you
have raw-format photos of the bird and a gray card in the same location
and light, someone else can help you make the adjustments.
The human eye (brain) is good at adjusting perception of color under
varied lighting, but the camera records the actual incident light. Even
worse, when creating the JPEG image from the raw data, it may attempt to
compensate for incident light color and do a bad job of it (like a
poorly colorized B&W film.) By preserving the raw data, you eliminate
the poor "colorization;" and, by photographing a gray card, you capture
the color of the incident light so the photo software can compensate
more accurately.

hen using digital camera for the violet end of the spectrum. Additionally, I
was shooting through a window.If I get another opportunity with this bird, I
will get myself outside and listen.In the meantime I will post this bird under
hummingbird sp.
