I'm coming from a similar place, with some reservations... I've always been slightly annoyed with the tendency to blow out reds into magenta and turn sky a little too cyan, but in general I think Olympus rendering has been pretty good, at least for images which benefit from the "punchy" contrast (some obviously don't). With the original filmic module, I was able to closely match the curve to the camera rending with the help of an IT-8 chart and a few beers. The settings were fairly extreme, which somewhat defeated the purpose of having a default with nice parametric adjustment available... but it was possible. The new filmic RGB features a custom spline which enforces more linearity in the midrange, and while I understand the idea behind it, I think it may be the source of some people's frustrations. Simply put, the "look" it provides is not one that everyone likes for everything, even with increases to local/global contrast, etc. My understanding is that one of the problems with the old version was a tendency towards oscillations, although I didn't experience this myself. If this could be mitigated to a reasonable extent, then adding an option to the new filmic to use something more like the old spline might be a real "crowd pleaser", and increase the general acceptance of the module... and the underlying idea of the module is a really good one! So, because I really like the idea of the parametric controls which filmic offers, my own approach lately has been a hybrid one: using a target shot and a variety of test images, I tried to find a generally sane default preset for filmic RGB without any extreme settings. It gives "reasonable" renderings of my camera's RAWs, even if they don't resemble the camera's rendering. Then, using the same corpus of test images, I manually created an "extra" curve to add a "knee" to filmic's relative linearity, bringing things close enough (not *quite* as "punchy") to camera rendering for my tastes. Applying both of these by default, I can simply disable the extra curve for the images which are better suited to "plain filmic"... and either way have some parametric control for adjustment. It seems to work well so far, but I'm absolutely not implying that this is a "correct" approach. :-) The attached style is what I'm using as of this moment; it may work well with Olympus 16MP sensor cameras generally, or may not, but it's an example of what I'm describing, for whatever that's worth. I also so some color profiling with the color LUT module, but it's probably very camera-specific, hence not included in the style. So, that's my two cents! -- jys ____________________________________________________________________________ darktable user mailing list to unsubscribe send a mail to [email protected]
