When should I "Open in Photo" when using Designer

[Nigelum]

I'm a newbie to using Affinity Designer 2. I just found out that I can "open in photo." I know that I should finish my illustration before using Affinity Photo to "fine tune," but Designer has some stuff that Photo has.

My question is: When should I use Affinity Photo? What qualifiers would be for me to say, "Hey, I'm done in Illustrator; now it's time to fine-tune/finish up in Affinity Photo"?

Basically, whenever it suits your workflow(s). You can switch back & forth between the two as needed -- you do not need to finish in one before using the other but it is good practice to save your work before switching in case something goes wrong during the switch.

Note that the native file format is the same no matter which one you save your work from -- the file extension only defines which app opens it by default but any of the three can open files created by the same version number of the other two.
