Hi all, I'm starting to experiment with combining several exposures to make one final exposure.
It might be a bracketed set in an HDR type scenario. Or it may be a series of nighttime long exposures, all stacked together to get star trails.
Given the talk about the not-yet-released Lightroom 6 -- I learned about what seems to be called a 32bit 'Pro HDR' TIFF -- I also see that when exporting a TIFF from Lightroom, I have the option of selecting 8 or 16 bits per channel.
Can somebody possibly help me understand the difference between a 32bit 'Pro HDR' TIFF (as in the Merge option) and a 8 or 16bit TIFF as exported by LR?
Here's why I ask:
1) I import all my RAW into LR
2) I make modest adjustments, such as ensuring they have the same White Balance
3) I export from LR -- here's why I'm interested in exporting as 16 bit rather than 8 bit per channel
4) I import those into an application that merges them -- either, say, HDR or star trails.
5) I export from that -- and here's why I'm interested in the 32bit 'Pro HDR' TIFF...
6) I import that back into LR and do more editing.
SO...
I want to maintain the best fidelity from LR, through the merging application, back into LR -- retaining the most detail and ability to adjust highlights and shadows.
I hope somebody here will understand what I'm talking about!
Thanks in advance, -Scott
