A friend of mine suggested you may be able to explain the blue haze on the horizon of the attached, the photo was taken one morning while on a sailing holiday in Greece and accurately reflects what I saw – I thought it was an illusion and never expected it to show on the image.
Upon questioning, this additional information was provided:
The image was taken with the camera on my Z10 phone set on auto; I think the file properties have that sort of info in there.
We were sailing around the Gulf of Volos in Greece at the time, having left a small anchorage called Nies at around 6.30 that morning, heading out of the Gulf.
The photo was taken around 8.30am on May 7th by which time we think we would have been passing the Trikeri Penisula (on the right), I don’t have the charts here so can’t give you a name for the tip of land to the left as it isn’t named on google maps. Our position would be around 39o 3’N, 23o 4’E.
That morning was cool and very still, the sky had thin broken cloud when we set off, and there were some pockets of early morning mist over the land but not a blanket of it. The day before there had been some wind, but nothing above a F5, and no storms.
Is this Rayleigh scattering? Or is something else going on in this image? Please help; thank you!
