AP 1.5.1.54 Windows, Difference between a New Pixel Layer and Duplicating the original Background

[artofmtl]

Hi,

Maybe it is a stupid question but can somebody explain to me the difference between adding a New Pixel Layer and Duplicating the original Background. For example in one of the videos of Affinity Photo - Non-Destructive Dodge & Burn - https://player.vimeo.com/video/155533670/they show to burn and dodge non destructively by adding a new pixel layer. This video is just an example but many times I saw in the different videos the same principle.

 

By duplicating the background layer instead of adding a new pixel layer I am achieving the same thing?

Thank you

Initially, the new pixel layer is empty -- there are no pixels in it. That's why in the video, Edit > Fill was used to fill it completely with 50% grey pixels to give the Dodge & Burn brushes something to work on.

 

When you duplicate an existing pixel layer (like the Background layer), you are filling it with the same pixels as the original.

I think I got it, thank you R C-R.
