Introducing neural restore module – raw denoise, denoise, and upscale

Night landing, high ISO

Taken on a photo trip with the club. Nikon D7000 + 70-300 VR, f/5.6, 1/500s to prevent motion blur, ISO 1600, then +3.4 EV in darktable; exported at 1/4 size, upscaled in chaiNNer using RealESRGAN_x4Plus, loaded into Gimp as layers, merged after lowering the opacity of the upscaled layer, exported at width 2048. Can you come up with something simpler / better? I’d like to avoid turning everything into a mush (and I’m not satisfied with my result, but it’s an old camera, so…). [2024-09-18-18-53…
