Halos are definitely seen as a defect by photographers, but it's not at all clear to me that they should be seen as such generally.
If you've ever had a class in drawing, you were probably taught to put halos in on purpose. In photographic terms, it increases acutance, but in drawing class they simply say that it makes the shadow appear darker, or the highlight brighter. Halos are very poppy, and pop sells. Pictures of your aircraft with halos all over the place might well sell well, they're punchy, they look different, and nobody who hasn't been trained by TPF to look specifically for halos is even going to notice them.
It's not "straight photography" but, really, what the hell is these days?
