Stacking RAW files

[dkj]

What happens when I select a collection of RAW files for a stack? Are they automatically developed with the default settings in the Develop persona?

Hi dkj,

When you stack RAW files, there aren't any settings from the Develop Persona applied due to it using a different pipeline for batch processing.  You'd get much better results by processing the RAW files individually via the Develop Persona, export them and then stacking the processed images

Thanks for your answer. Processing the RAW files individually would be rather inconvenient if I'm stacking a dozen or more images. But all I do in the Develop Persona is use the ROMM RGB output profile. Might there be some way of automating that? Or some other way of ensuring the output of the stacking preserves the extra data?

I came up with this process:

1. Select File:NewBatchJob on the menu.
2. Add the RAW files to the list.
3. Check Save As TIFF with these settings:
   • Pixel Format: RGB 32 bit.
   • Resampler: Bicubic.
   • ICC Profile: ROMM RGB
   • Compression: None.
4. Select Save Into and select or create a directory for the TIFF files.

Then use the TIFF files to create the stack. The new images will have the ROMM RGB profile. 

I'm hoping this will preserve the colour data present in the original RAW file. Is there some way to check whether this is so?
