Any part of the image that has a non linear stretch applied to it is artistic (doctored). However, what you see in the image was picked up by the camera, so where do you want to draw the line?

That's true... but different parts of the world experience different seasons. Although referring to this equinox as "vernal" isn't astronomically inaccurate, since it occurs where the Sun intersects the vernal point (itself a north-centric definition, of course), calling it the spring equinox is pretty much an error... especially in an international forum like this. "Vernal equinox" isn't ambiguous; "spring equinox" is.

Equinoxes are very interesting days! Happy Spring to you all.

Those terms are now rather dated, the preferred ones being the March and September equinoxes, and the June and December solstices. For our many friends in the Southern Hemisphere, they are looking today at the beginning of their autumn season, not spring.

(Technically, the Sun can't possibly follow the same path on both equinoxes, because that path is described by about 12 hours of time, and the equinox is marked by a single instant. So the paths are very close- certainly the same to non-instrumental observation- but not identical at all.)
