Hello, rawtherapee team!
Recently, I am looking for a raw image processing program that support linear base curve. I found both rawtherapee and darktable are good candidates for me. Through comparison, I think rawtherapee has better compatibility, because it supports dcp and lcp profiles, while darktable doesn’t. So I want to stick with rawtherapee.
However, I found some problem in False color suppression (FCS) option. In short, it grays the color too much compared to the color smoothing (CS) option in darktable.
Here are some comparisons, both using AMaZE method, and have disabled chromatic aberration, defringe, and lens correction:
rawtherapee (FCS = 0) vs. darktable (CS = 0)
(Because only 4 images can be uploaded in one topic, I will try to upload them in the reply)
rawtherapee (FCS = 5) vs. darktable (color smoothing (CS) = 5)
Without FCS and CS, rawtherapee and darktable nearly show the same results, with some false colors near the edges of the text. The false colors are well suppressed with FCS = CS = 5.
However, in the sense of pokers, FCS = 5 make rawtherapee grays more, especially in some narrow or small color region, while CS = 5 in darktable still keep the saturation well.
I am not familiar with demosaicing and FCS algorithm. Are there some parameters like suppression radius, threshold, or strength which are not shown in the user interface? I am looking forward to some improvement in FCS.
