Extract frame within orginal image | Art print

[Charlotte Ruel]

Hi,

I don't know who to ask, so I'm trying on here. I'm entirely new to Affinity (and have never used Photoshop).

I create oil pastel paintings and want to have a digital file of each of my paintings (for my website and for art prints).

I've taken pictures of them, with the right lighting and camera settings. I've tried to take them as straight as possible but they are obviously not a perfect rectangle, and I don't want to lose any part of my paintings.

My question: How do I select my painting (within my original picture) and make it a final straight rectangle (final picture)? I understand that, because it's not a perfect rectangle in the beginning, there will be a small distortion, but I am fine with that.

I've attached a document to try and illustrate my point. I hope it's clear.

If anyone could help me, it'd be great.

Thank you.
