no AWB??
of course there is. all it does is let you change the WB from what the cam has interpreted.
i only shoot raw.. you have to have a WBin rawfor the image to be seen..

The technique that I use to reasonable effect is thus:

1. Focus on one part of the panoramic view
2. Press the AE-L button to lock the exposure
3. Select manual exposure
4. Take as many shots in the sequence to complete the panorama
5. Using Panorama Factory, create the panorama - I don't use exposure correction

And this is the result:

I have read many time that White Balance is not reflected in RAW. It may show up in the imbeded JPEG but many settings do not even show in RAW.

Check this link: www.adobe.com/digitalimag/pdfs/ps_workflow_sec3.pdf

This Whte Paper on Raw Workflow states "shooting in raw white balance is only saved as an EXIF tag. In fact when you'r shooting raw the only setting that will have a significant impact on the raw capture is the ISO setting. Virtually all other camera settings that you set on the camera will result only an informational tag that conversion software may or may not use when processing the raw conversion."

Taken from A Digital Workflow for Raw Processing Part Three: White Balance

EXIF tags exist but do not have anything to do with the raw conversion.

The point is no matter what the EXIF data says you can adjust the white balance however you want (Make all the same) when doing the raw conversion. If you used the same setting for all photos the raw converter may not use that same setting unless you manually adjust the settings.

Surely, if you lock the exposure before taking the sequence of shots, then isn't the WB the same for each shot.

Using manual focus on the first shot keeps the focal distance constant for each shot & also stops the camera from resetting the exposure as the shutter is pressed for the next shot.

I agree, I exposed for the fastest shutter speed over the area I was taking the pano over at a preset aperture. This is so hilights are not blown out in any frame (In a pano the angle of the sun changes drastically). If shooting in raw, you must make sure all conversions are consistant. The raw converter will not necessisarily automatically use the same settings when converting to tiff or jpeg. You can assure all settings are the same during the conversion process.
