Switching between Kelvin and -100 - +100

maxwellg2013  wrote So I want to make preset packs to sell on my wesbsite but I have now realized why my presets never turn out right. Since I am taking photo photos in raw I am adjusting the temperature in kelvin scale. whenever I make a preset it is just saving kelvin value and applying that to other photos instead of just adding 35 percent sometimes adding a specific kelvin to a photo increases the temperature by like 400 %.I just want to make presets where i can know that the preset will consistently raise the temperature up by +25 like you would with a  jpeg file. Anyone know how I can use that style of the temperature slider? Thanks! Max

The other reason why it doesn't work is that Kelvin values define a large range of possible colors and each camera will provide a differing metadata suggestion making the possible colors even farther apart. The concept of altering WB like this is rather pointless as -100 is ambiguous and the settings should be done visually, NOT numerically to provide a pleasing rendering from each raw.

More about this from a colorimetric standpoint:

You can do this with a Graduated filter. Add a graduated filter and drag it all the way down, so that the filter covers the entire image. Set Temperature to +25 and save this as a new preset.

It’s by design. Kelvin scale is only used for raw files. For jpegs, tiffs etc. adjustments are relative. These files, unlike raw, don’t have color temperature values recorded because white balance is already “baked in” and Lightroom detects this automatically.
