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

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?

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.
