I am new and have figured out how to brighten my photo of my original artwork (watercolor design) enough that I was able to get the erase paper feature to work. So now I have the gray and white checkerboard pattern that shows that the watercolor image is on a transparent background. How do I save it so that only the colored part is applied when I put it into another document. Do I need to either cut out the the color image from the transparent background or save it as a particular type of document so the transparency is saved. Right now when I try to expert it, it is still showing the white background. Thank you! I am sorry if this is something obvious. I am new to using Affinity Photo for this and have tried to search forums and online for something to clarify this and haven't found it.
