I got it (cont.)

Learning from Mr. Boris_@s7habo how to make a monochrome image (Editing moments with darktable - #120 by s7habo)

Not a challenging one, but I’m curious to see if anybody else has other monochrome approaches (but color renderings are welcome as well)

The story behind this one is here, since it is from the same shooting session.

(And can’t avoid thinking how close this (Jan/2020) was from the drastic changes and deaths COVID imposed to the whole world…)

Oooh, ooh, loves the monochromes… :laughing:

Sucking the color out of an image just opens up all sorts of possibilities. Here’s what I came up with, in rawproc:

I wanted contrast in the chunks of ice, and I got it with two things: 1) a control point curve, and 2) ludicrous-ludicrous HSL color saturation. In fact, here’s a screenshot in-process, with the saturation tool selected for display:

All these shenanigans are, as you can see in the toolchain, before the conversion to monochrome with the gray tool, which was just the bog-standard perceptual mix of the channels. A crop to accentuate the horizontal-ness of the composition, oh, and to also remove the slight vignetting occurring in the corners, and 'ere y’go.

That’s the sort of warped thinking that goes into my monochromes… :crazy_face:


It was around 40 °C at the time (high South summer), so the ice must have melted… :stuck_out_tongue:

That’s not ice? Boy, am I losing it…

My kid is still at the South Pole, so I’ve been regarding ice photos all year… :crazy_face:

My fun in GIMP 2.10.24 unfolding to Lab, removing a and b, then Luminosity mask


Two versions with GIMP, one black and white, the other added a blue colour cast - so still monochrome!




To try to add to the serenity of the scene, I have made the image almost monochrome and cropped to a more panoramic aspect.


I like a lot the second one.
Maybe too different to the reality, but who cares (not me)

Glad you like it, but now I think that I should have reduced the saturation by about 30%!
My latest attempt to achieve what I had in mind is still not right.

thanks for this play

I’m not good at B/W (though I love it). But this was such a nice shot that I couldn’t avoid to try it. Congrats!
BTW: time to clean your sensor! :wink:

Slightly improved (and simplified), at least to my taste. And with another crop.

I leave it as an exercise for the student at home to take care of the sensor dust. :rofl:


Sloppy me :blush: … so sloppy (to say the least) that I managed to completely brick this camera a couple of months later while trying to connect a damn cheap macro extension tube :sob:

Thanks to all contributors!

Yet another attempt at this beautiful photograph. This time even more panoramic, only the slightest hint of colour and a bluish cast.


I did this mostly to show that you can use negative RGB channel settings in the gray output. I don’t know why the module on shows only positive settings. You have to enter a negative number to change the slide bar scale.
