First time panorama shots and a problem
Hi there panorama guys!
I'm just starting out with panorama photography. And was hoping
you can help me with this. My setup consists from bottom to top of:
tripod, ballhead (clamp bubble leveld), 360° panoramabase with clamp,
nodal slide with clamp, L-bracket with camera in vertical orientation.
I'm using a 28mm lens on an 1.6x crop body. The image below consists
of 12 shots all taken with the same exposure and fstop (f8) in manual
mode. also white balance was fixed. As you can see there is some
blending errors with the first few frames to the left. How can sth like
this happen? I turned all bells and extras in the panoramasoftware I use
off and only had it stitch the unedited images. I think that rules out the
software as a source of the error?!
The image covers almost 180°
Sometimes the problem exists, and sometimes not. Maybe it's because
of the angle towards the sun? If so how can I still get blendable frames?
Here is another (less obvious) example (~10 frames):
Thank you very much!

I've also noticed it works better if I use the exposure lock on the D50

Please feel free to edit my images...I can only learn from it.
Two questions:
1) Are there any auto functions still enabled on your camera:
focus,
exposure (highlight exposure selection is particularly bad),
white balance
2) If you are using a raw converor, does it have any data adaptive features?
Turn them off if you can.
Also, the stongest banding appears to occur with the strongest highlight and greatest dynamic range.
Keep on stitching!

I set my camera to manual (exposure and focus) and custom
white balance. On the PC I converted them with RawShooter
to jpegs where I again checked that all images had same
shutter, fstop and color temperature.Covnersion was done
without any manual or automatic software editing.
You are right about where the banding occurs, the bands
itself seem to be the edges of the individual frames. So
I suspect that it comes from some form of vignetting
as the lens gets hit by direct sunlight. I'm going to make
a few tests with different lens hoods on the weekend
to see if that's the error. I'll keep you posted.
