I prefer Image 105 to 101. How about you?

Looks to me that the purple fringe was replaced by a yellow one, equally
unsharp.


Ah, you're absolutely correct. That's what I get for being lazy and
trying to do the plane in one fell swoop (that's what also caused the
artifacts you mentioned below). So I went back and corrected the
fringe piece by piece using the freehand selection tool. I think
you'll find it looks a lot better.

Perhaps the answer lies in a better lens?

As far as I know, chromatic abberation is caused by the lens, not the
camera, so the best policy is to tackle the problem where it occurs.

That digital photo site whose URL I've been posting gives a very
technical explanation, saying it actually has something to do with
microlenses, which are part of the camera, not the lenses you attach.

But I'm not a professional photographer, so this is just my two cents...

And yes, the yellow in the top wing looks much better in pic 105, but
unfortunately the publicity on that wing now suffers from artefacts.

Not that I could have done any better, but since you asked for an
opinion... ;-)

Seriously, thanks. I was embarrassed after reading your comments,
which impelled me to do better. More could be done to this picture,
but ultimately you're dealing with an image that started out less than
completely sharp, perhaps because the image was too much of a blowup,
the camera's resolution wasn't that great, the plane was just moving
too fast, or some combo of these and other factors. Still, it's a
cool pic, and if you don't try to print it too big, it is quite
satisfactory.

(This is the pilot that died recently, right? If so, I hope I did him
a tiny bit of honor by making his plane look better.)
