Well, first let me say... I think the:

Color balance turned out very good on both the 2 and 3 shot flavor.  Wood color desk and walls look very natural.

However, the ceilings might need a bit of adjustment. While looking at the Zenith.. there are definate shades of gray/white between the 2 and 3 shots.

Suggestions: You probably already know that the ceiling hue differences was caused by the intense window light brightness.  Using the Automatic Exposure Lock and shooting the first 1st shot at the darkest part of the room should help balance out the ceiling shot lines.

I noticed that these are QTVR. Have you tried using the java flavor?  Do you get nearly the same results?

Just a thought this Sunday morning here in Texas.

Happy Holidays

Please use larger value in "Blending Width" of the manual stitching panel, which will make the Ceiling/Floor more naturely.

Or, you might download a new version, the default value of the "Blending Width" of the manual stitching panel is changed to 5 instead of 1.
