I have an old Photoshop CS5.5 license in case of emergencies, though it&#x27;s Windows only. On the Mac side I&#x27;ve been using Pixelmator.<p>HDR and panorama merging are native in Lightroom now, so I don&#x27;t have to use an external editor regularly anymore. I&#x27;m honestly surprised some bureaucrat at Adobe didn&#x27;t stop them from adding those because they&#x27;re competing with Photoshop rentals.<p>As an added benefit, Lightroom merges into DNG files that keep all the data. Back when I had to merge stuff in Photoshop it flattens down to a TIFF and you can lose information out of the highlights and shadows.
