P: LR4 doesn't display point curve adjustments made in LR3

Chris... check that button on the lower right corner of the tone curve dialog. Then your 'problem' should be fixed.

I did more testing. Started again in LR3. Had a look at one of the images that was picked up by the script:


Then the same image after converting the catalog to LR4, no script yet:


After the script ran:


After I switched the process to 2012:


Then I finally set the curve to high contrast - where it was before, and it had no manual point-curve adjustments as far as I can tell. Just a holiday snap.

Either I am not properly understanding something, or you are not there yet, Tom.

Let's see what the others say.

I did the recovery using the recovery script as outlined in the mail

I found that

a) the tone curves are now preserved

b) the script adds two new history steps:
- Before point curve recovery
- After point curve recovery

I assume those new history steps are due to this alpha test and will go in final release, am I right?

Then I found this:

c) when I switch an image over from the 2010 process to 2012, my custom tone curves get replaced with very similar looking ones, except they now are composed of a lot of points instead of the few points that it had before. This way the custom tone curves become pretty much useless to me.



Is this due to this fix? If not, and it's a general thing, this is actually a huge issue for everyone who uses custom tone curves and wants to benefit of the 2012 process.

Tom, please let me know if you want me to open a separate ticket for this.

Oh, I experienced a strange behaviour of LR.

I created a new catalog for script testing purposes in LR3. I copied some pictures from my main source and imported them into the new catalog.

And... the picture with the manual tone curve I loaded and selected in LR4 last week had its settings still manual but the dialog showed: middle contrast and the preview was just like in LR4!

I was getting nervous then and loaded my old main catalog and everything was fine with that picture.

???

I was really confused.

Then I installed the script, ran it and... everything was fine. All images got their old tone curves back even this weird behaving picture but: the fill light settings were modified for this photo from 70 (even in the history before/after restore) to 45 (just the value of my used preset).

??????

I was more confused.

Is the xmp-file broken? I don't get it.

So far, the script seems ok.

As someone who (ab)uses tone curves, I'd love to test out the proposed fix.

Hi Tom, was one of those who volunteered to help test a solution, but haven't received any email with a script on it. I have a catalog with some 60,000 RAW images in it, and am more than happy to run any script on it to see what is the story.

many of these images had their tone curves changed when I did the first conversion.

Cheers,
Steve

Okay. I think there are two problems:
* point-curves - they are lost during the conversion from 3 to 4 and apparently recovered by the script.
* adjusted region sliders that get based on the wrong curve during the process-change from 2010 to 2012.

I just don't use point-curves that frequently in Lightroom, hence the script didn't find that many.

When I switch the curve from custom to linear, all is fine again. But I do not want to do that for every single image 😞

Okay, did what I promised. Converted the catalog again. Found my test-image with a curve setting of 0/0/-3/-13/Linear - so the values weren't lost.

But: the process still is 2010, when I switch to 2012, something odd happens. The settings get changed to 0/0/-3/-13/Custom and curve and image are looking wrong.
This image is not picked up by the script.

First glance at the script: I was surprised that so few photos ended in the collection. So I looked for others in the LR3 catalog that had individual curve settings to see whether they were passed over - no, the curve settings were there. Now I can't say whether they were corrected by the script or didn't have the problem before. I will have to convert the catalog again. Will be back.

BTW: What scripting language is this? Can I use it for my own work?
