This presentation for the RA Photo Club for Aperture users who are looking for alternatives.
As a long time user of Aperture, my workflow has evolved to make use of this tool that has been discontinued by Apple, and will not be supported after September of 2016. I have over 18Tb of photos handled by Aperture, and a new tool was needed. After looking at Lightroom which would not import my libraries with changes, I gave Capture One a try.
Here is the presentation handout.
