When I compare the DFP6 light leak previews with what I get in DPL6, I find that the leaks are rotated by 180 degrees, when the default light leak orientation box is active.
I’d expect the light leaks to be applied as shown in their preview.
Marked in green: rotated light leak
Marked in magenta: Default light leak orientation box
Some of the leaks appear even more disoriented.
What’s the logic here?
