See-Through Edit (Affinity Photo)

[koolkon12]

Hello, 

I am relatively new to Affinity Photo. I want to do an edit similar to the included edit of the car. I have two photos, one that will serve as the background and one that will be in the foreground and be erased from. When I try to add the second photo as a layer, it does not snap in its original dimensions and appears to have barrel distortion. I have not found any tutorials that discuss these topics/issues.

What method are you using to add the second photo (place, copy & paste, something else)? Is the resolution (dpi) the same for both photos?

I am using place to add the second photo. Both photos are the same resolution. Could the issues be because both photos are raw format (ARW for my camera)? When I begin the edit, I open the photo that I want to use as the background (the reveal photo), click develop, and then use place to bring in the photo from which I want to erase a portion of, revealing the contents of the reveal photo.

I think you should open and develop both of your raw images, then drag one onto the other. Trying to "place" a raw photo may not do all the development steps as you'd want them done, much as batch developing raw images produces a different result than manually developing them.

Thank you for the suggestion. I will try that out.

Doesn't developing raw also apply lens corrections, hence the difference on the placed undeveloped image?

The placed image must be developed, as without developing it it's not an image. The question is what processing that version of the development process does. Lens correction is certainly one aspect of development that might occur differently (or not at all) in the scenario where you try to place a raw image rather than opening it.
