Preliminary answer here, for and regarding the masking: Always try to spread the histogram over all the available nodes, so you get maximum control over your whole dynamic range. Highlights may fall into the 0, -1, -2 EV band, that doesn’t change anything. Tone equalizer knows no highlights, it just splits the dynamic range you feed it in 9 zones, spaced by 1 EV. Use of the Luma tab of the Equalizer module or the Lightness tab of the Color Zones module will also yield pleasing results, depending on what exactly you want to do.įorget about highlights. The L channel/curve in the Tone Curve module is probably what you’re looking for. Yes, I use the exposure module with the screen blending for my manual vignetting correction – I find it gives me better quality than the vignetting module. A beautiful (well, … depends ! □) and natural looking image. No unexpected or weird effect as far I can see. Then tweaks with contrast and SOP if necessary. Center the histogram with slope, enlarge it with contrast until before clipping, and balance the image with power. Lookup table with camera profile preset (optional).Ĭolor balance (slope offset power). The histogram is more reliable (and faster). It happens to have max Lab at 96 and still saturation zones on the image. Considering only color picker may be misleading. Keeping grey at 18%, play with black point and dynamic range against histogram still keeping room on both side to avoid clipping. Center the histogram (set as linear) visually keeping room on both side to avoid clipping (the automatic clipping fails some times). Then I’d change the demosaicing to FDC and apply a Denoise Profiled luma preset to get something like this: MiscĮxposure. If it affects other colours in the frame you could apply this with a drawn mask. In dt I use Denoise Bilateral Filter: maximize all the values (radius and RGB channels) and apply the Color blending mode.
