For what IŽve red, there are quite a few in-camera considerations for later successfully coming up with a panorama in PS (the following seems to apply to land photography):
1-Using a tripod
2-Leveling the camera
3-Overlaping 20-30% of the shots
4-Shooting vertical despite youŽre looking for an horizontal panorama (to reduce distortion)
5-Shooting manually with parameters (speed, f, WB) set to a compromise in between all the segments
6-Going longer than 35mm in focal lenght to reduce distortion
7- Pivoting the lens around a nodal point to reduce distortion effects of parallax
So far so good, but now I want to translate this UW for shooting a large panorama of an UW mountain that must be more than 100m long and I sincerely have no idea of how undertaking it:
-Mountain base is quite deep (>50m) so tripod seems not to be the way to go (I know it has been use in shallower water with wrecks, ie) and therefore parallax and assembly problems will be high
-Going longer than 35mm UW is no option, but I doubt in between tokina 10-17 (at 17 barrel distortion is bereable) or Nikkor 12-24
-How may shots for section do you estimate IŽll be needing to have chances of coming up with the panorama? Do I need to stick to the nodal point theory or I could just swim all along the wall making photos at the same distance/depth?
Or should I just drop this crazy idea? (last but not least )
Hope to get your input, guys!!!
