Lightroom displays a curve not of my making

[Michael West]

a user preset....generated curve....

ive never seen anywhere near  that many points on a curve, don't know how id ever make such a beast. but Lightroom generated it from the data in a user preset.

Did you perhaps create your preset curve in an earlier version of the "Calibration"? I have seen similar complex-looking multi-point correction curves when I applied a preset created in e.g., Version 3 while running LR's Version 6.

I suspect the curve is being adapted to compensate for differing "under the hood" tonal correction values in the more recent LR version?

it may well be. Thank you.

it didn't present a problem just a visual jolt...

I think I understood what you offered..

only raw version developer 1 and 2 of lightroom introduce a curve by default...
