In Nik Collection 8, Meta-Presets were removed based on customer feedback. These presets — which in fact were based on Adobe Photoshop actions — were rarely used, and advanced users preferred creating their own Photoshop actions to have even more control on their edits. As a result, the Meta-Preset feature was discontinued in version 8.
This information applies to versions: 4, 5, 6, 7
Prior to version 8, Meta-Presets were Photoshop actions designed by Nik Collection experts, allowing users to apply a combination of filters and settings from various Nik Collection plugins with just one click.
