Some photos from the first visit to the zoo [wherein I run into some of Lightroom's shenanigans and learn why all beginning photography books advise you to stay away from fiddling with colour spaces]:

This sucks. Apparently Lightroom isn’t WYSIWYG! [Update: apparently Lightroom uses some strange colour gamut to render in the editor, which is separate from the one used to export. These exports are ruined, so I'll have to start again. It means that everything I've shot since I went to a wider gamut has probably been exported incorrectly. Luckily, I procrastinated on exporting most of it. ]
