I usually get the windows cleaned, or do it myself, if I'm going to be taking pictures on the flight, and there's no abrasions on the flight-deck windows. Optically they are obviously not perfect, being of a sandwich construction and nearly an inch thick.

After doing some more research, I'm wondering if it's something to do with differing amounts of diffraction of different colours. What I don't understand is why the effect would be worse on the K3 than on the K5. Here's an image of diffration through a prism.




As I'm generally shooting at an angle, the windows probably act as a prism. I wouldn't notice blues so much as they are generally sky or water. On the ground I can also see the effect, though to a lesser extent, on my FA24-90mm at 90mm wide-open. (f4.5). It doesn't happen at all on the K5. On my old Tamron BBAR 90mm f2.5 lens, it doesn't happen at all at f2.8. I'm wondering if the K3 tends to use the red end of the spectrum more for phase-detection AF than the blue end, resulting in greens actually being oof and therefore smeared? I've just adjusted the focus on the FA 24-90mm and will try it out on my next trip.

I am shooting RAW. I'll post some examples tomorrow. I've just been looking through a few shots again, and I've realised that for some reason any slightly oof areas are much worse if they are bright green.

Has anyone noticed the K3 tending to smear greens/ yellows when processing files heavily? I've seen this reported elsewhere (though only green was mentioned), and have come across it myself when processing aerial shots, which require expanding a very narrow histogram. So much so that a batch of shots I took over Turkey recently are unusable. With shots not requiring heavy processing, I never see it at all, except with a couple of crap lenses I own. I'm wondering if it has something to do with shooting through windows, using lenses that aren't sharp enough for 24mp. The biggest surprise has been my FA 24-90mm, which still works splendidly on my K5, but produces this effect on the aircraft at any aperture, and sometimes even on the ground when wide-open, on my K3. My Sigma 24-60mm doesn't seem to be affected.

I'd be interested to know if anyone else has noticed this, and also if anyone has any theories into what is going on.

I agree with Smeggy and the Doc. If you want this sort of image, why use a high-tech camera? A Diana or a smartphone would do just as well.

Saying that, I've messed around recently with dSLR shots processed on my phone, so I may be the pot calling the kettle black.

I hardy ever use mine, I found it was not wide enough, so I got a Sigma 8-16mm. I love using really wide lenses. Architecture is probably their forte, it's certainly what I use it for most. It's not just how much you can get in the shot, but also how much you can use perspective. For landscapes you need foreground interest: they are great from a low viewpoint on a rocky beach for example, or with plants in the foreground. They also work very well on images with strong leading lines, ie piers, roads, railway lines etc, due to the exaggerated perspective.

The 10-20 is a tad soft at the edges, but improves when stopped down. As with any UWA lens, it's a good idea to use lens corrections on the image, the one available in Lightroom works particularly well.

Not many entries so far, surely a few more of you have something in the archives?

Here's a link to download Camera Raw 6.7

I think it was the last version for CS5. The instructions for installing it are at the bottom of the page.

A very interesting and unusual portrait. I love the greens.
