Intensity Color Grade

[exhaustino]

Is there a way to adjust the intensity of a color grade in LrC?

I am looking to grade a set of 62 images to give them all a cohesive look. They are interiors and exteriors of a building so not all of the original colors are exactly the same, so I expect to have to adjust the strength of the setting depending on the specific image. The ideal process would be to choose the hue(s), copy and paste it to all images in the batch, then increase or decease intensity per image as needed.

Is this something that can be done in LrC? Seems like it would take forever and be imprecise to do individually with the color wheels in the Color Grade panel.

The alternative would be to do something similar in PS but that seems problematic as well in terms of having to do each edit individually.

Running LrC v11.5 on macOS 10.15.7

Create a preset with the color grade selected. Include the fader option. When you apply the preset, use the slider to increase or decrease the intensity.

What I am realizing is that after I added the color grade as recommended [edit: to the batch of 60+ photos all at once] and want to now adjust intensity on individual images, the fader doesn't show up [edit: when an individual photo is selected] unless I click the preset again. It is applying the color grade again on top of the existing grade though because before I click the preset, I can toggle the color grade on and off in the the develop module on the right. I am, in most cases trying to reduce the grade and make it a bit more subtle. Should I be looking somewhere other than the User Presets list on the left so that I can adjust the already-applied color grade intensity?

Unfortunately not. You could do a general look with the color grade and use this to create a Profile via Camera Raw. (In camera Raw hold Alt/Option to turn Create Preset into Create Profile from the three dots menu)  You'd get a slider for the look using Profile in the Basic panel, but using a slider with a preset requires it at the time of application.
