Please Create a way to select photos that have been treated with "Black and White" Or allow presets to apply tags so when you create a black and white preset it is tagged so you can select all your black and white images. I need this because sometimes I want to apply a synced adjustment to only my black and whites, or sometimes I only want to export my black and whites.
Interestingly 'Treatment' only sees images changed from colour to black & white. It seems not to see black & white film images. I use keywords to identify b&w film images and to record what types of film were used.If keywords have already been applied to the B&W image files you can use the Library Filter Text> Keywords to find them.
If keywords have NOT been applied AND the B&W film scans were saved as 'Grayscale' mode files you can use a Smart Collection to find them. This will find ALL Grayscale image files in your LR catalog and not just film images.
Thanks very much for your reply. I did guess that that was the situation. That being said, I hadn't noticed that there was a Treatment option in the metadata search, so I had been using keywords for both film and digital images. I don't want to change my B&W film images to grayscale. I like to keep my options open.
