[QUOTE="J-see, post: 537181, member: 31330"] I toyed with levels a bit to check what happens: [ATTACH=CONFIG]200599._xfImport[/ATTACH] [ATTACH=CONFIG]200600._xfImport[/ATTACH] [ATTACH=CONFIG]200601._xfImport[/ATTACH] Assuming you shoot RAW, the posterisation occurs during processing and exporting as JPEG. There's too much information being compressed and this can result in gaps between tones. It usually shows in (gradient) skies. You should be able to fix it by adjusting curves or toying with the exposure. The RAW itself should be fine (when 14-bit). You can also fix it afterwards by adding a little bit of noise to the affected areas and applying a Gaussian blur to that. [ATTACH=CONFIG]200603._xfImport[/ATTACH] The artefacts around the edges of the bridge are JPEG artefacts likely caused by compression (or maybe multiple edits). [/QUOTE]
