[HDR-photo] HDRI Book and Jpeg brackets

[Sam Kittner]

Firstly, I want to thank Christian Bloch for his outstanding and  
engaging HDRI handbook.  It's a super resource.
As someone who has been working on hdr and panos for just about a  
year, the book confirmed many things I have been
doing and opened doors of understanding to many things I haven't been  
sure about.  I really appreciate the workflow examples by
Dieter Bethke and Uwe Steinmuller...as well as Bernhard Vogl's  
contributions to the pano chapter.  Many thanks to them all.

One interesting item I found in the pano section was the hint to  
shoot the bracketed images in jpeg format (yes, with all in-camera  
processing options
turned off).  I have been shooting raw format (nefs) since I began  
shooting digital in 2001, primarily for the flexibility of the file  
adjustment.
For my pano work I have shot raw...making no adjustment to the raw  
files...then convert to tiffs (yes, storage space nightmare (I often  
shoot a pano scene though dawn or dust and come away with hundreds of  
exposures))...then work with the tiffs to get the hdr and tone-mapped  
tiffs to stich.

But I can see the reasoning behind shooting the hdr intended images  
as jpegs to save storage space and, as importantly in many situations  
with movement issues, the faster write speed...therefore the ability  
to shoot the pano faster...the jpegs then are used to create the hdr  
and resulting tone-mapped tiffs for further image editing.

Does anyone see reasons not to shoot hdr intended images as jpegs?  I  
will do some tests for myself, but wondering if there is any  
difference others have found?

Many Thanks,
Sam
