Question on Apple Background Image Removal when using with Affinity Photo ?

[augustya]

Hi Guys,

I wanted to ask you guys a question, now that the background removal functionality is also embedded in iOS 16 and in the photos APP where you just have to long press on the image and the Photo APP automatically removes the Background for you.

However it is not perfect, the end result often has some areas where you have to tidy up things either Paint out unwanted areas or paint in areas that have been missed.

Now to do this what I do is for areas that have not been removed, on the background removed image I add a Mask and paint in with Black to remove the unwanted areas, and areas where I have to bring in the missed areas I add a Black Mask to it and then Paint in white to bring in the missed areas, and here is where the problem arises.

So what happens is, after you remove the background using Apple’s Software the image is automatically resized to a new ratio and size, and for my task of bringing in missed areas I have to place the original image (Without the background removed ) on top of the background removed image but they do not fit/overlap on each other properly, because the original ratio of the original photo is different and the size and ratio of the background image after the removal becomes different. So my question is, what can I do ? How do I make sure both the image become of the same ratio so that perfectly overlap on each other ?

I hope you guys understood the question clearly ?

Hi, I followed this thread when you posted it hoping to read a better answer than I have myself. But since nobody has replied here it goes.

I've done the same thing several times for other reasons, not due to using Apple's background removal feature, but the same issue applies. You have two overlapping images that you want to line up but they're scaled differently which makes it hard.

I always make the top layer 50% opacity and then use trial and error to scale and position it so that it matches the bottom layer. Then I restore opacity to 100% and flatten the layers. This works but it takes time and it would be nice if there was an easier way.

Yes, I was a little surprised and astonished that there are so many Veterans, Gurus of Affinity Photo here...And almost all of them use Apple device and still nobody was able to provide a solution on this. That came as a shocker !! That such a basic thing and the Gurus here cannot think of such a simple thing. So I had learnt this method from someone else online, not here...That yes decrease the Opacity of both the layers that would help align both of them in the same ratio.

But Thanks for the Heads Up. Someone replied here...Finally

Just one question what do you mean by flatten the layers ?

When you have two images on top of each other in Photo, you have two layers in the Layers panel. Flattening the layers means merging them together. Right click the top one and choose Merge Down in the Layers panel.

How does Flattening help in this case ? Where my intention is not to merge them in one I just want to make corrections on the new layer based on the original ? Just curious is it applicable in my example ?

It's not necessary if you're discading the second layer when your'e done whereas for me I need both layers.
