current19:58, 17 April 2019Thumbnail for version as of 19:58, 17 April 20197,416 × 4,320 (2.39 MB)ColinTaken from https://www.eso.org/public/archives/images/original/eso1907a.tif 16-bit original. Converted to 8-bit with dithering using Photoshop 2019. Saved as JPG with maximum level 12 quality. This file is smaller than previous one because the previous one had noise or extreme dithering which does not compress well.
18:19, 13 April 2019Thumbnail for version as of 18:19, 13 April 20197,416 × 4,320 (10.49 MB)ColinSave from tiff at maximum quality 12 from Photoshop 2019 (previous had approx 10 which produced some block artefacts visible at high magnification). Source TIF image has some random noise which is likely inherent in the production and requires minimal compression to reproduce faithfully in JPG. First version uploaded was likely smoothed.
