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

Could someone please post instructions on how the script is applied to the catalog.

Well, I guess you're right. My test were rather, mmm... formal or... synthetic, but in a real world workflow restoring an old curve after touching the file in LR4 would be dangerous indeed.

Hi Bob,
Before doing anything non-reversible I would suggest you do a test and a handful of images.
Develop them (a copy of them!**) in Camera Raw 6.6 into something *recognizably-strange*, e.g. a solarization.
Then import them in LR4.0 and look if this develop effect is still available.
If yes, I'd consider it safe to start with these images importing them in LR4.

Which is what I expect, because a "read metadata from file" solved this problem already w/o the script for many people.
It was just not usable on virtual copies, as VCs are not written to metadata, hence nothing there to retrieve by invoking the extra read-command.
Root cause of this effect was that the catalog conversion from LR3 to LR4 ignored the tone-curve-entries in point mode from LR3.

**Actually if you store a safe copy of these images for some time, inaccessible for LR4, you could go right away importing the "working-copy-images" into LR4.
Should it go wrong, you delete them from LR4.0-catalog and wait with importing from the safe until LR4.1.
Costs you redundant storage space until verification of success.

Good luck, Cornelia

Yes, I agree with Beat: if I have touched an image in LR4 I have made conscious changes (no matter if I decided to still leave it at PV10). Auto-changing them back would be rather dangerous...
If I want the script to pick such an image I have first to go back to it in LR4-develop and set its history some steps back to where LR3 left off.

I don't think redistributing is bad: everybody knows this is an alpha-test, so entirely at our own risk.
Dorin & Beat have published what this script succeeds in doing and what is still not solved by it.

So whoever wants to give it a try knows what to expect.
The risk-averse better wait for LR4.1, how long ever that will be...

Waiting for that scrip !
Thanks

frankly I don't know if redistribute the script is correct: I received it directly from Adobe and I suggest to wait for something "official", public ... and deeply tested!

Could someone please post a link that works to get the Tone Curve Script?

Thank you.

Agreed, although IMHO those should be separated out, because the processing in LR4 might have been done on a wrong base.
