are those jpg OOC or post processed?
As for my 3 images, they're the large (lotsa MB) jpegs with tonal curve adjustments. My better angel tells me I ought to be devoted to raw and to relishing each opportunity to work in SPP, but my lazy devil is pretty satisfied with extra fine extra big jpeg. If I do another Sigma project at the coast, though, where the highlights are searing and glare can cause banding in the sky, I'll stick to raw/SPP/tiff to LR.
