solsticephoto Posted April 12, 2020 Share Posted April 12, 2020 Looking to find the "create selection from luminance" (alt-ctrl click on layer thumbnail) on the iPad version of Photo. Any clues ? Quote Link to comment Share on other sites More sharing options...
Staff Callum Posted April 17, 2020 Staff Share Posted April 17, 2020 Hi Solsticephoto, There is no way to do this on iPad at the moment I'm afraid. Thanks Callum Quote Please tag me using @ in your reply so I can be sure to respond ASAP. Link to comment Share on other sites More sharing options...
solsticephoto Posted April 17, 2020 Author Share Posted April 17, 2020 @Callum, thanks for taking the time to respond. For a black and white layer can I not just "load to pixel selection" from one of the RGB channels ? Also, research has shown this missing feature was identified long ago. Are there plans to add this capability to the iPad version ? NotMyFault 1 Quote Link to comment Share on other sites More sharing options...

Perhaps that could help or point in right direction. Macro attached below. Luminosity Mask.afmacros Luminosity Selections.afmacros Quote M1 IPad Air 10.9/256GB lpadOS 17.1.1 Apple Pencil (2nd gen).
