32 bit to 16 bit conversion
« on: March 02, 2014, 11:40:27 PM »

If I convert a 32 bit file to 16 bit the HDR Toning dialog should pop up; instead I get shunted to ACR as a filter. I'm using the most current version of CC.

The file just opened from ACR and HDR before that. I don't want to do ACR again.

What's wrong?

Thanks.

Found the answer to my own question and it is:  there is a check box under file handling in Photoshop preferences regarding 32 to 16 bit conversions. The default is to use ACR; so uncheck it.

What I am doing is a new HDR process; don't know who deserves credit for this but I learned it from Lewis Kemper. It is probably already here on this forum somewhere, but here are the steps:

Select files in Bridge
Tools/Photoshop/Merge to HDR Pro
Select 'Complete Toning in Adobe Camera Raw'
In ACR: set all options to suit as usual.
Image now 32bit
Flatten [Or keep working as smart, 32 bit file.]
Convert to 16 bit and select 'Exposure and Gamma' on dialog
[Must first set a "file handling" option in preferences to prevent this step jumping back to ACR a 2nd time]
Save
