As I said, Stefan, I can't use a polarising filter as I am shooting through laminated glass; the lamination causes coloured bands that look like oil on water. For the same reason I am not allowed to wear polarised sunglasses at work.

Love the first one, the eyes are amazing!

I like the second and the last one; the first one could do with a bit of room above her head, but it's a lovely portrait.

Nice shots, though 2-7 look like they could do with more contrast. What a bunch of nutters! The guy in #4 looks like the wind is lifting him off the bike. I like the look of the gas-turbine bike, even if it is slow!

Hope you enjoyed the flight! Shame the picture is a bit blurred, you'll have to go up again and take another one!

Thanks for the replies! I will trawl ebay as you suggest John. A shame that I missed your sale of filers on there. I only thought about using a colour grad filter the other day while messing around with colour filters in Lightroom. I have used a standard nd grad with some success but a tinted one, if I can get the right colour, would I think give much better results. Aerial haze actually looks much worse on a photograph than to the naked eye, I guess because our eyes pick up a much greater range of frequencies. However, if I can find a way of reducing the blue tint caused by this haze, I would imagine I would get more contrast and detail, as there should be less scattering of light.

I should have an IR camera soon, and am looking forward to trying that out, aerial haze does not affect IR anywhere near as much as it does the visible spectrum. The only downside is the pics will all be mono. I did have the probably completely nutty idea of trying to take an IR and a colour picture of the same scene, converting them both to Lab Colour, and taking the Lightness channel from the IR picture and replacing the same channel in the colour pic with it. I think it would be extremely difficult to get the replacement channel to line up though, especially as the cameras have different resolutions. I would need two identical lenses too. You reading this, Richard? If anyone here could work out if this would be possible, my money would be on you

Apologies for an unusual and perhaps nerdy sounding question, but I was wondering if anyone knows if there is a graduated filter available that will progressively remove blue, and increase contrast, towards the top of the image? Does anyone know if such a thing exists? Or any ideas how I could make one? Ideally, I would like to find a filter that is graduated from the middle to both edges, so the sky and foreground are not affected.

A consistent problem with aerial photography is that the image gets more blue, and loses contrast, as the scenery recedes into the distance, due to the increasing amount of atmosphere between the camera and the ground. Also, if I select a part of the image from the horizon to halfway to the foregound, the histogram only covers perhaps a third of the range from 0 t0 255, for example from 80 to 160, sometimes much less than that. I can't use a polariser because the windows are laminated (it causes prismatic effects). A graduated orange/amber filter would block blue light, but also green light, which is not desirable. Tiffen do colour grad nd filters, but they are incredibly expensive (£257.99) for the square ones, which is what I would need, and I am not sure exactly what colour or density is required, so it would be a very expensive experiment. Apart from that, I can't find anything online. At the moment, I use Lightroom grad filters with a light orange hue, which helps.

Am I right in thinking that a filter on the camera would allow more information to reach the sensor, and therefore allow more latitude to tweak the picture in PP?

it went for £22.37, looks like a bargain to me. Anyone here get it?

Thanks very much for that, cabstar. I will have a look. I'm almost certain that I'll never hear from them again once I mention money, but I will go through the motions.

This all seems to have gone a bit off-topic....

I have a digital subscription to American Photo, and it was nice to see such a positive article about the Q. Jonathan Barkey was obviously very impressed with the build quality and features. He did say "We'll be interested to see if they've achieved a jump in quality or if the Q's output will be more like that of premium compacts compacts like the Canon G12 or Panasonic LX5.

They quoted a price of $800 with a 47mm lens, which works out at about £485. No doubt it will cost a fair bit more in the UK.
