trevburley Posted August 24, 2017 Share Posted August 24, 2017 Affinity Photo for iPad I was experimenting with the Apply Image filter last night on AP for iPad and I couldn’t seem to understand the correct workflow necessary to get it to work. How do you select the other layer as the source? I selected “Current Layer” then changed my selection to the grey scale layer which I wanted as the source, enabled equations but nothing happened? At this stage I would expect to see a greyscale image since all the equations are set to D=S by default? Never really used the “Current Layer” button on desktop either as I’ve always used the drag method. Can’t find any information on it?

Stanley Posted August 24, 2017 Share Posted August 24, 2017 As I understand it, if you select 'current layer': S is what you see before you start Apply Image, D is what you see after Apply Image has done its calculations. The default for all channels is D = S, so when you start Apply Image what you see doesn't change until you have changed an equation. An equation calculates a number, from 0 to 1. Try setting a D channel = 0.5. AP's help says that 'current layer' blends a layer with itself. I think it would be better to say that it calculates a new image (D) from what you see before you start Apply Image (S). And therefore Blend mode seems to have no effect. There seems to be a bug. After you have changed an equation, you might need to disable, then enable the Equations button to see the change. trevburley 1 Quote Stan Link to comment Share on other sites More sharing options...
trevburley Posted August 24, 2017 Author Share Posted August 24, 2017 Thanks Stanley - understood, so to your knowledge the ability to use a second layer as your source (by dragging it) doesn't exist on iPad (yet) as demonstrated in this video at 0:57? I would have to workaround by exporting the layer to a file and use the 'Image' method?

Stanley Posted August 24, 2017 Share Posted August 24, 2017 That's what I think, you can't drag files in iOS 10. Maybe 11? Quote Stan Link to comment Share on other sites More sharing options...
trevburley Posted August 24, 2017 Author Share Posted August 24, 2017 I was just looking to drag a layer, not a file. Would be nice if there was a third 'source layer' option which allows you to click another layer in your project and use that. Thanks for the help Trev Fonebone 1 Quote AP Windows, Mac, iOS --- AD Windows and Mac, iOS Link to comment Share on other sites More sharing options...
