Thanks for your replies guys. I guess what I was looking for is much more complicated than I realised. I was looking for a pixel-by-pixel horizontal translation of an entire image, and it looks as if this is only possible using sophisticated programming that is WAY beyond my expertise. Next time I’ll take the photo right in the first place!

Is there a way to create a mirror image in Photo? Not a horizontally flipped image, but one where, for example, a person at the right edge of the image looking out of the image would be still at the right edge of the image but looking into the image? If not in Photo, can anyone suggest a program or plugin that would do this? I realise this isn’t strictly speaking a mirror image, but I can’t think of a better way to describe it - maybe a horizontal translation? Thanks.

From 01:44 in the Live Filters tutorial for desktop Affinity Photo you demonstrate a technique using live filters and the Paint Brush tool, which involves inverting the layer and then applying the Unsharp Mask filter with the Brush. In Affinity on the iPad, am I correct in thinking you can't do this in the same way, but you have to make a selection first and then apply the filter?
