I've been doing some training on Macphun Luminar and created some free workspaces and presets. In case you would like copies here they are. And if you need to buy your own copy of MacPhun Luminar visit http://bit.ly/MacPhunSoftware and use the code PHOTOPLUGINS for $10 off. Enjoy.
UPDATE: I have changed the link to the files for the workspaces and presets to a Dropbox link. While dozens of people were able to download the files as I originally shared them, six people couldn't access them so I am trying this method. Download all the files in zip format at: https://www.dropbox.com/s/eb5cplv7komonrs/_LuminarEmailPresetsWorkspaces.zip?dl=0
