Question

Preset color setting etc are totally different in preview than after launching in

May anyone encountered the same issue: my custom presets in lightroom cc look like totally different: if I launch them they will be not the same. Yes I use graduated filters etc but why do they mess up - in compare to the preview?

Any idea? Thanks

vgcsaba, can you upload that photo and one of the presets to Dropbox or similar and post the sharing link here? That could help identify whether this is the same manifestation of the reported bug or something different.

"I still suspect noise at ISO 8000 has something to do with it."

The bug can be reproduced with low-ISO images merely by creating a preset on a non-raw that changes Temp and Tint and then previewing that preset on a raw:

Again yes. But - at the obvious risk of being seen as argumentative 🙂 - I just want to point out that the descriptions of this bug, as in the feedback thread, all describe changes in white balance only, temp or tint or both. Not a different color rendering altogether, like we see here. What we see here is not a change in white balance. This is something else.

It's all fine with me, I don't have any money in this. I'm just pointing out that it doesn't fit the pattern, and maybe there is no bug at all involved here, just a fully explainable phenomenon in high-noise images.

A bug in rendering a preset hover preview could plausibly produce results that you couldn't otherwise get by changing sliders in the Basic panel. A bug, by definition, behaves differently than we expect the program should.

All it would take would be to make a few passes with a local adjustment brush and adjust the temp/tint and you could achieve the two results shown.

"this isn't a white balance issue"

Right, it appears to be a bug in the rendering of preset hover previews.

It appears that most of the reports involve presets with adjustments for Temp and Tint that were defined on non-raws, and then applying those presets to raws. Those presets adjust the internal IncrementalTint and IncrementalTemperature settings, which have sliders in the Basic panel for non-raws but not for raws. The only way to apply IncrementalTint/Temperature to raws is via presets or copy/paste/sync.

Yes, but my point was that adjusting temp or tint, whichever way it happens, will not turn one of these into the other. This is a difference in color rendering that has to be something else than the reported bug.

I still suspect noise at ISO 8000 has something to do with it. Yes, I know the Sony alphas handle high ISO well (I have one), but there will be a lot of noise at ISO 8000 regardless.

Different resampling algorithms for the two previews, or different resampling ratios for that matter, can easily produce dramatically different results if the image is noisy enough. Unless it is viewed at 1:1.

I think you could get from one to the other using local adjustments using Tint and Temp. The only way to know for sure is if the OP upload a DNG for us to analyze.

OK, but this isn't a white balance issue. There's no way you can get from one to the other just using temp and tint.

I suspect this is an extremely noisy image (it was shot at ISO 8000).

With all noisy images you need to view at 1:1 to get a true representation.
