It’s been a long time since I first had the intention of creating this update, but LR/Mogrify 2 version 5.00 is finally available, and it now includes support for ImageMagick 7!
If you’re a Mac user then you just need to update to the latest version, the plugin includes a pre-compiled version of ImageMagick 7 all ready to go.
If you’re a PC user then you can simply update the plugin and it will continue to work with your existing ImageMagic 6 installation. However, you may now choose to point the plugin at an ImageMagick 7 installation instead, that way you know you’re getting the latest and greatest image processing!
