I've been editing a group of pictures I took in Boston over the past couple of weeks. The first group was taken at Constitution Beach, where I stood on the beach shooting over water to the taxiway at the beginning of Runway 22R. I was shooting between 6 and 7 p.m., and the low sun was shining weakly behind some high clouds. I was quite surprised to find that all the shots from that session are unusable due to heat haze issues.
A week later I was out at Castle Island, again shooting over water. This time the planes were on approach to Runway 4R, so there was no asphalt or concrete anywhere that could have affected my images. I got some OK shots from that session, but also quite a few with the too-familiar heat hazed ripply pattern along the horizontal lines.
Is this heat haze giving me this grief or the effect of the humidity being pumped up from the water that's interfering with my shots?

Heat Haze is simply the difference of temperatures between two different altitudes which in fact bends the light to make a reflection or an alusion of wavy air.
You can get heat haze anywhere over anything. Water,Pavement, anything!

Quoting Jetmatt777 (Reply 1): Heat Haze is simply the difference of temperatures between two different altitudes which in fact bends the light to make a reflection or an alusion of wavy air.
To be specific, as air along a surface heats, it expands and rises. Light is refracted through the changing density of the air, the result is what we call heat haze.

Also note that the weather does not need to be hot to have heat haze. It occurs in all temperatures. I've had shots severely heat hazed during -20 degree temps!

Thanks for the comments. Yes, I've had the unfortunate event of heat haze in cold weather, too. No fun. I guess for some reason I was under the impression that the condition was most prevalent over pavement. The water in Boston Harbor was probably about 58 degrees F, according to a web site I found. The outside temperature when I was shooting was about 70. That doesn't seem like that much of a temperature difference - is 12 degrees enough to cause heat haze?
