HDR RAW file and Lightroom

Postby jpottermac » Mon Aug 08, 2016 3:30 pm

Hi. New User.

1. If I open a 48 Bit HDR RAW file in Lightroom and save changes, is the infrared data lost?
2. Why doesn't 64 Bit HDR RAW file appear in my scan options? I only have 48 bit HDR RAW. Are they the same. My scanner is the Epson V850.

Thanks

Dear user,

48 Bit HDR RAW files do not store the infrared channel. Only 64 Bit HDRi RAW does.
Make sure you are in normal transparency mode.
The V850 does not offer infrared scanning in reflective and full area mode.

Kind regards,
Arne
