No problem. If you check the xmp you will see I used an inferior inversion method (rgb curves instead of invert module) which makes it a bit too bright compared to nicer tonal rendering such as the version by @Thomas_Do . Oddly enough, I am usually guilty of undersharpening, at least compared to others who post on PlayRaw. Oversharpening is prevalent, but no one ever seems to comment on it haha. I was trying to mask it out of highlights and shadows, but it makes darktable impossibly slow on this machine, so didn’t bother.
Thanks for providing the image. I’ve been wanting to hone my negative skills more.
