Blender AgX in darktable (proof of concept)

[Donatzsky (Nis Donatzsky)]

@kofa

Please, I’m glad people find the code useful but what I have done and will do is just the mechanical stuff: exposing the controls of the curve someone else created, applying matrices someone has designed.

That’s essentially what Apple did with the iPhone

@paperdigits

So while they provide a nice test case, almost nobody will have images like that in real life & testing against real images is still important.

Here are some:

Guys I just discovered LEDs

Hi everyone. I recently discovered something called “LED”. I now own two LED appliances - one called “RGB light”, and a “Royal Blue 10W COB LED”. Here’s one of my first tests: [My favourite lenses under Royal Blue and RGB Red LED lighting] Processed with experimental program. So excited about the creative potential of LEDs! And proud to be an early adopter. (Yes I know LEDs have been around for years) EDIT: I think my first edit was a little too light? [dimmer] 5D3_9253.CR2 (23.5 MB) …

Deliberately difficult gamut colors in macro shot of hex nut

As a companion example to this topic I created, View/Modify color matrix in DCP files , I deliberately shot this extreme macro of a hex nut, 1/4" by 20, lit by incandescent bounced off a slightly yellow ceiling, with a background of pure blue (rgb 0, 0, 255) displayed on an LCD monitor. I had to export as tiff with tamed gamut, and then do curves on that tiff before export, hence me sharing two sidechain files used to get to the final jpeg shown. Have fun, and feel free to use this in any so…

Difficult orange flower

Very difficult orange flower pic. My workinprogress program, preserving tonality (but failing to preserve colourfulness, unnaturally pale): [flowersp] Rawtherapee 5.8 auto-matched curve, 4400K, very posterised: [Screenshot 2021-09-18 at 18.02.58] Lightroom, also 4400K: [Screenshot 2021-09-18 at 18.03.23] I would say lightroom’s average shade of orange looks most like the actual flower, but this is just a case of lucky clipping. 5D3_0104.CR2 (23.7 MB) This file is licensed Creative Co…

Flower Power with Roses

I took this Picture like 2 Years ago when i started photography.

Red Rhododendron... why are some flowers so difficult?

I thought this plant was looking particularly good this year so grabbed the camera. Watching the in camera JPEG on the screen while still looking at the real thing showed what a poor job the camera was doing. The default DT effort was terrible too. I’ve tried myself with Darktable but looking out of the window… my efforts still look nothing like the real thing - some parts of the petals end up looking pink and the whole thing looks quite dull. The real thing is a lovely deep red… there is no pin…
