As we all know, Aperture is no longer being developed. However more and more third party applications are popping up on the App Store — some for very little money — that may fill in the some of the gaps while we wait for Photos to be released. In this post, so that we can take advantage of some of these new apps, we look at Aperture’s built-in “Open in Editor” command, and the significance of the few options it offers. We also look at the many options you have when saving at TIFF file from Photoshop. Warning… this is a really, really long post.
