LR Classic - Camera Profile Management

Thanks so much for sharing your process, "placeholder" approach and other info.

It didn't come across, but your default "placeholder" - is exactly what my meaning was, when I said "blank".  Obviously nothing can be blank - but neutral settings/default/typical/standard or whatever other alternate wording you choose.... just as you've done in your example!

Thanks again.

KE_DP  wrote I know I can delete (or move/copy) profiles by going to - Library / Application Support / Adobe / CameraRaw / CameraProfiles /

You do realize that if you delete a custom user camera profile that is assigned to image files those files will be assigned the topmost alphanumeric named profile in your user folder.

KE_DP  wrote This is not actually a "camera" profile - this is a lightning and color profile for a very particular set of hardware and shooting conditions.  Change lenses?  Different color.  - Move to a different location?  Different lighting etc. The thing is we are shooting these references, hundreds, thousands of times and just don't want to keep them all around as "presets" since they are created only for very specific conditions.

It's only necessary to create a new camera profile onsite if the lighting is other than daylight or tungsten type. This assumes you are creating dual-illuminant profiles using those light sources. For example fluorescent, mercury vapor will benefit from creating scene referred camera profiles. For most lighting situations simply shooting the ColorChecker or white balance card and using the WB eyedropper to white balance the image will work well. You can test this for yourself by comparing images with the scene referred custom camera profile and a virtual copy using a reference dual-illuminant profile created with Daylight and Tungsten light sources.

You can toggle the visibility of groups of profiles and presets using the methods shown here: Julieanne Kost's Blog | Updates to Lightroom Classic ­- Profile and Preset Management, Color Labels, and Auto-Stack​ or here: https://lightroomkillertips.com/lightroom-classic-7-4-update/​

It would be great if we could easily group profiles together to make this toggling easy but apparently you can now only create new profile groups through Camera Raw.
