Hi, I have all settings in Lightroom (Edit -> Preferences -> External Editing) set to export files as TIFF and ProPhotoRGB. However, when I use the QImage add-in, the files that get exported are AdobeRGB, according to the Embedded Image Information window in QImage. In contrast, when I export images from Photoshop using the QImage add-in, those files are ProPhoto RGB as I expect. I am unable to find any additional setting that lets me control the color space of the file that is generated by the QImage add-in. Can anyone let me know if there is a way to control this, or if this is a limitation of the add-in? Thanks.
I will attempt to offer some inside ideas.
Unfortunately, I do not own Lightroom so I can't try to repeat what your issue is.
But, some thoughts. It seems illogical that from Photo Shop it comes through embedded and from Lightroom Qimage CHANGES it.
I believe that when there is NO EMBEDDED profile, Qimage will use Adobe RGB as the default colorspace.
Next item is reading the color space from the QU hotbar. If the colorspace is EMBEDDED, Qimage will show it with Asterisks on either side of the colorspace. Otherwise, if Qimage is using a default Adobe RGB, there will be no asterisks.
Last idea.... Put your image into the queue. Right click for the menu. Select CONVERT. At the bottom of the box, you can invoke a profile to profile conversion.
The FROM box says, <input> The TO box you click the Browse button and select the Prophoto icm
Make sure the PERFORM conversion is checked.
When you look at the resulting TIFF you should see Prophoto with asterisks showing it is embedded.
Hope some of this helps.
