I've recently upgraded to LRT4, while pretty happy with LRT3. Even after reading your instructions many times, I'm still experiencing weird results, and have numerous questions. I'll try to break things into simple questions...
- when using HG or deflicker, I understand classic exposure setting is not used anymore. Instead I've found it's somewhere hidden inside gradients. Is it normal we can't access no more to these values from within LR ? I see 4 preset gradients but none of them handle the HG or deflicker exposition variable.
- still using HG, there is a column named "HG lum leveling" just next to the classic exposure column. What exactly are the numbers I read here ? Obviously, there are not exposure values, because where I should get 1/3 exposure difference because of a 1/3 exposure variation when shooting, I go for ex. from -0.032 to -0.015. which is very far from 1/3. Still, it seems to work, but those numbers are total mystery to me...
- I'm working on a stereoscopic shot, where I've badly set my cameras. One eye is full raw, the other one is sRaw2 (half definition raw), instead of both sRaw2.
Both eyes were shot stepping exposure at sunset, so I need HG feature on both. Runs smooth on full raw, but not with sraw2. Seems that HG works ok, but when using LRT visual previews I have unexpected crazyness from time to time. What happens here ? Is this because of Canon sraw2 ? I'll try to convert to DNG first but I've really never had to do it, since workflows are usually long and complex enough for trying avoiding this extra step. LRT3 was always fine with sraw2, btw...
Here are 2 screencaps, fullframe first, then sraw2. Same settings applied of course on both :

- About visual preview : some days ago I've noticed hidden folder within the raw folder I was working on, containing visual preview thumbs. Now I don't see it anymore with other sequences, and when I switch from one folder to the other I have to recompute visual preview each time to get it back displayed. Aren't those supposed to be cached ? Is this something we can set somewhere ?
- I also went back into a really old sequence, that used to be tweaked with previous LRT version. I've trashed any previous xmp files, renamed the raw files (had to do it for reason). Where I should have started with something LRT should think is new to him, I was still left with previous settings, such as crop window and some other "ghost remainings". How is this possible since name changed, xmp were trashed and erased, etc ? I remember previous versions used stubs. Does LRT4 also uses them ? If yes where are they stored ? Can't find any!
Thanks a lot for your precious time, hope I don't waste it too much with my questions...
cheeers,
