If you use Photoshop to create or edit an image then it will contain embedded information about the ‘Color Mode‘. To set up a dropdown attribute that displays and allows you to search for the ‘Color Mode‘, follow these steps:
- Create a new attribute of type ‘dropdown‘ called ‘Color Mode‘. Click ‘Show on search‘ if you want to show the dropdown on the ‘advanced search‘ page.
- Add attribute values with the following names and IPTC/EXIF Mapping fields:
- Bitmap: 0
- Greyscale: 1
- Duotone: 8
- RGB Color: 3
- CMYK Color: 4
- Create an ‘embedded data mapping‘ to map the embedded field XMP:Color Mode to your attribute.
