current03:43, 7 July 2021Thumbnail for version as of 03:43, 7 July 20215,184 × 3,456 (5.23 MB)JPxGTo heck with that. Original image with exposure +1.000 with GIMP
07:59, 6 July 2021Thumbnail for version as of 07:59, 6 July 20215,184 × 3,456 (4.43 MB)JPxGBrightness up 20, contrast up 10. Let's see how this looks.
07:53, 6 July 2021Thumbnail for version as of 07:53, 6 July 20215,184 × 3,456 (3.63 MB)JPxGReverted to version as of 07:44, 6 July 2021 (UTC): I guess I just don't know what the heck is going on here, all of the shadow-lightened versions look markedly worse.
07:51, 6 July 2021Thumbnail for version as of 07:51, 6 July 20215,184 × 3,456 (4.67 MB)JPxGEither there is some bizarre glitch in MediaWiki's file rendering, or I have done something incomprehensible to this image (lightening the shadows should not make the image darker). let's try 40%
07:47, 6 July 2021Thumbnail for version as of 07:47, 6 July 20215,184 × 3,456 (4.5 MB)JPxGThis is far too aggressive, and looks like ass when rendered in a browser. Trying again, with the shadows only upped by 30 this time.
07:45, 6 July 2021Thumbnail for version as of 07:45, 6 July 20215,184 × 3,456 (5.21 MB)JPxGShadows lightened by 60 using GIMP to give better visibility.
07:44, 6 July 2021Thumbnail for version as of 07:44, 6 July 20215,184 × 3,456 (3.63 MB)JPxG{{Information |Description=The Shell refinery (not owned by Shell currently, but that's what it was called before). Not to be confused with the other Martinez refineries. |Source=A freakin' camera. |Date= |Author=JPxG |Permission= |other_versions= }}
