Portrait mode is perfectly fine- it isn't a filter or form of editing.I wonder this too. I’m curious if like a portrait mode on a newer I phone is ok, or if vibrant filter? I don’t usually end up using those... but I’d have some great pictures if it was allowed...
I have the same question. I apply the vibrant filter to some of my photos too because it helps to make the colors of my subject pop out but still looks natural. Of course to keep it looking natural I lower the percentage of filter to under 35. I'm wondering if that counts as an over-edit or minor change.
Example:
Original
Filtered (35%)
This isn't the best example since the picture is not well lit anyway, but it gives you an idea of what I'm talking about.
