What's with the purple tint of the branches on the top half of the picture? An artifact of postprocessing or does it come from the lens?

@laubblaeser Pretty bad chromatic aberration in the upper part, but not really sure why (lens is a Sigma 18-200mm f3.5-6.3 and usually only has occasional issues in the far corners). But also not a fan of editing too much, but in hindsight maybe should have... 😇

@laubblaeser I appreciate that it wasn't edited heavily even if there are imperfections!

@Gargron Same here. I expected that it was CA but wasn't sure if it's maybe deliberate artistic choice from post. Still an interesting artifact and somewhat unusual nowadays.
