Hello,
1) I edit first my pictures in lightroom. Prophoto colorspace right? "Correct" histogram... no clipping
2)export to photoshop in prophoto , tiff 16 bits.
Prophoto colorspace in photoshop.
3)in attachments (left lr, right ps), histograms result...
( on screen the picture is the same in lr and ps).
so... which one to believe? Should i adjust one more in ps?
thank you very much.
Note that the histograms will not, and are not supposed to, match completely.
The numbers represented in the Lightroom histogram are not ProPhoto RGB. They are in a custom color space with ProPhoto primaries, but sRGB tone curve. This is a different color space from ProPhoto RGB with gamma 1.8 tone curve.
You will see this difference even more clearly if you open from Lightroom in other color spaces, where both primaries and tone curve are different.
If you enable Proof in Lightroom, the histogram is represented in the proof color space.
