For airshows, I dial in +1.0 or sometimes +1.3 exposure compensation on the K10D and select spot metering. This reduces the tendency for black outline shapes.

Great shots, I like the shot of the yellow plane with the white cosses on the wing, Was he doing a loop :
It was probably a wingover or a barrel roll.
That looks like a pretty risky stunt flying through those flags
The really scary displays are the ones where they do the same stunt inverted (not in a Tiger Moth, though). I suppose you could argue they have a better view of the ground, so it's easier to judge the height...

It certainly used to be a production aircraft, and there are a handful still flying. I had a ride in one once, around the Cambridgeshire countryside - it was part of an event at Duxford.
If you're interested in a bit of its history, there's a Wikipedia article on it.
Some good captures in that series of pictures. Exposures particularly good, I thought, with good detail visible underneath - hard to achieve sometimes against bright skies.

I think the 1st one is the best as well.
Normally a sky as featureless as this, yet taking up as much of the frame as it does, would make a picture very dull, but the transition from blue to pink from left to right adds just enough interest.
That empty expanse of sky, together with the solitary horse (?) gives a sense of peace and solitude that are most agreeable.
The transition from the enclosure of the bay to the limitlessness of the open sea and sky add to this, and leave me a with a sense of calm. I like it.
I don't like the second one - the beach takes up a lot of the frame and is quite dull, and the knobbly rock thing in the middle has nothing to recommend it in its own right, and it's so dominant that it takes attention away from everything else.
Edit: interesting that the 'knobbly rock thing' is also in the first one. I hadn't noticed it as so offensively dominant in that. Somehow it seems to be present, but by balancing the outcrop on the left where the horse is, it's not drawing excessive attention to itself. Maybe also because it's not so central.

ChrisA discovered a glitch, when testing in a different thread last week...
The shutter didn't open, (I took the lens off to have a look) and the battery needed removing and replacing to get the camera to reset itself. On replacing the battery and switching on, the shutter opened and closed, and thereafter the camera behaved normally.
No grip in my case.

im buying a wide angle lens for landscape hdr photography - still the right lens?
But if you do choose wide angle, I can't see how HDR is relevant.

Hello All,
Advice needed!
I am considering buying a Pentax 10-17mm Fisheye to get some ultra wide shots with my Pentax K10d , my standard lens is a 18-55mm - if i bought the 10-17mm lens would i benefit from a greater wide angle perspective i dont actually want the fish eye i just want ultra wide!
At one point does the 10-17mm start to fish eye if its all the way through the 10-17mm it may not be the lens for me?
For rectilinear (which means that straight lines are straight, not curved the way they are with fisheye) extreme wide angle zooms, there's really only a choice of two at the moment:
Sigma 10-20 (about £300)
Pentax 12-24 (about £500)
AIUI, the Pentax (which I don't have) is very good at the getting straight lines straight bit, although IIRC, one or two have said that it has noticeable chromatic aberration (which is mostly correctable in software).
The Sigma, which I do have, shows a bit of barrel distortion (also correctable in software) at the wide end, but virtually no CA or purple fringing. It's probably not quite as sharp as the Pentax, but the Pentax is a lot more expensive.
I guess you pays your money and takes your choice. Though 10mm is significantly wider than 12mm.

In most cases I'd rather see a burnt out sky and a clearly visible 'plane than a black series of dots.
This is one example of where I thought the sky held a bit more interest:
