White Balance in Panorama
Jul 6, 2015 10:18:09   #
Morning Star Loc: West coast, North of the 49th N.
 
Here's the situation:
In a theatre, 59 kids from Middle and High Schools receiving awards. Letter sent home beforehand with the specific request NOT to take photos during the ceremony. Finally all kids back on the stage and THEN the announcement is made that unfortunately the photographer didn't show up.
We were sitting about 3/4 back in the auditorium, no house lights on, stage lights only.

Since I had been intending to take some photos of our grandson with his award afterwards, outside, I had my camera with me, with a 40-150mm lens on it. Took three photos of the kids on stage: left, middle, right. Then they started to move around.

When we came home and I looked at the photos they were as orange as orange can be.
So this is where the PP came in, maybe something for someone else to keep in mind.
I started with fiddling with the WB on each separate photo. Even when I used identical settings in ACR, the WB was still somewhat different between the three shots.
Finally deleted all my edits, made a panorama of the three orange photos (PSE 12), that worked like a charm.
Then started to play with the WB again (opened the pano as a raw image), and sure enough, this time I managed to get the WB even across the photo.

Unfortunately, I don't have the originals on this laptop, and we're away from home...

Great work and a good tip on white balance for a panorama composite.

I agree with your process of WB after all of the stitching, etc.

If you have ACR why not batch process before and then do your photomerge in raw.??

Very simple. Each photograph by itself is going to have a bit different WB point. So, when the stitching time comes around, each of the images has its individual WB. The problem has not gone away.

Once all of the images are stitched the new image has its singular colour "profile" and can be dealt with a single time.

This, of course, implies that the images were made within a reasonable amount of time of each other and with similar lighting in each of the images.

Please forgive my question I'm a little confused here. What was the camera WB setting? Was it set to auto?

I tested some software that I ported to a Mac by stitching a 5 shot letterbox panorama and did the WB after stitching and had no problem doing the WB afterwards.

The program was originally written to be run on a Linux box, then a couple of years later I ported it to a Windows box, and last week I ported it to a Mac. The original code was written around 2002 or 3 and was primarily used with scanned film images.

I could elaborate on the after the fact WB vs applying the WB from one image to all the others, but I don't have time to write a dissertation on the subject at the moment. In addition, it's a persnickety reason anyway.
