White balance with JPG

Archived from groups: rec.photo.digital (More info?)

I know the value of RAW and how much easier is white balancing with
RAW. I have experience having done that.

If, however, what I have to work with is a bunch of JPGs, are there tips
to obtaining a nice balance above and beyond just eyeballing it?

Specifically, with a stream of images illuminated by evening sunlight as
well as an external flash, the two differing colors in light are giving
me a very difficult time finding the balance. (Tried levels, curves,
color balance and had very similar outputs) These images do not have
white objects or black objects (beyond distant shadows inside tree
leaves). I might find a gray tone but only by way of a shadow cast onto
the skin of a subject.

Even if I had a RAW version of these and still had no white/gray objects
for basis (which I'm accustomed to) what, quantitative techniques would
make it easier?

If the photo session began with a white object, or a gray card, could I
use this as a benchmark and then slide each image under my adjustment
layers for the "correct" look?

Don't know about this.

If you were going to do this, just set a custom WB in the camera with the
card first, no?

Hello,

You can try Color Pilot (http://www.colorpilot.com/pilot.html) - the
software for color and brightness correction.

The examples of white balance correction are shown here:

http://www.colorpilot.com/cp_ex07.html

http://www.colorpilot.com/cp_ex11.html

Color Pilot allows you to save the results of the preceding correction.
If
you have many photos with a similar color balance, it is enough to
correct
one photo and then to click the Repeat button on the
main toolbar.

You can download the trial version of the program from
http://www.colorpilot.com/load/pilot.exe

After downloading the program you can see the demonstration how to
correct
several photos. For that you should open Example 14 on the menu
Examples.

Best regards,
