Recognizing Heat Haze Before You Shoot...

Sat Jul 22, 2006 2:35 am

I spent a lot of time at LAX yesterday, many of them at the Flight Learning Center on Imperial Highway--they just added more hours, and there's a fantastic spot to watch planes outside on the 25s. I could live there.

Anyway, the day was warm (low 80s I'd say [~27C]) and it was noticeably smoggy with partly cloudy skies (it got cloudier later in the afternoon). I could see some heat haze through my lens when shooting across the runways at the planes parked, so I resigned myself to the fact that those shots might not come out. However, when I looked at the shots, I found that nearly all of them were ruined by heat haze--some look almost like oil paintings it was so bad. These included takeoffs, landings, and taxis. This was quite disheartening as I got a lot of shots I'd been waiting a long time for--flexed wing 747's rotating with the tower in the background, Air Pacific and Air Tahiti Nui landing and departing, etc. So in the end, there are a few salvageable shots, but it was pretty disappointing to see the day's pictures.

So in the future, is there a way to tell how close you have to be before the heat haze kicks in? As I mentioned, I could see it myself on the further shots, but not the closer ones. I'd like to go back and recreate the day before I leave (I've got about 2 more weeks in LA) but I'd like to make it a day where the photos come out. Do I need to wait for a clearer day? A cooler day?

Thanks,

Jeremy

I usually look for small lights at the distance to which I will be shooting. Small lights are usually landing lights or sometimes runway lights, etc. If from where I am standing, the lights seem to twinkle like stars, you'll have heat haze. Simple as that.

If using a DSLR this is easy to check.

Zoom on in the image and heat blur will be easy to see. I spent Saturday morning at my local last week and being this far north, 75+ degree heat in the morning caused a lot of my images to be blurred. Only off the runway stuff was OK.

Gary,

I did see it really clearly on the further stuff, but not on the shots of planes on the runway (or on the even nearer taxiway). Some of the airborne shots were hazed, too, but at least a few of those should be rescuable. Looks like I need to come back in the winter!

I haven't photographed a lot this Summer. I prefer Winter.

Roll on early mornings in December!

Don't wait until winter. You can have the same problem in winter as you can in summer. Example: this was shot on a 0*Fahrenheit day in Detroit.

Having been to that spot I know exactly what you are talking about. The shooting in winter is much better, especially in the morning and evening. If you have a digital camera zoom in as much as possible and look at cheat lines. If they look like waves you have problems!  Wink One thing I have noticed at that spot is wind from the ocean helps. If there is a 15kt breeze the heat haze is pretty much gone.

I was shooting at IGM one day it was 40 Degrees F and I had to wear a wool hat cause of the wind and there was still heat haze up the wazoo.

Matt,

I had a shot of the Air Pacific just like yours... except the flaps were full blown down... just barely missing the ground. And there's a tropical scene painted on the side of the plane. I *might* be able to salvage one shot if I make it small enough... I hope  Sad

Oh well... I'll look at the weather and try to spend another day or two there. Heck, I only took 1030 shots, and some of them, at least, came out  Smile

Heat haze kicks in when a hot body  Wink is radiating heat to the surroundings; main factor for it to appear is a big temperature gradient or difference. As others said it can appear during cold days (if the temperature difference between runway and surrounding air is big enough). I guess your best bet is to go shooting early morning before the runway/ramp gets heated by the sun.

I don't have that problem in Winter at all. Very cold frosty mornings are best.

Wrong, we do get lot's of sunny Winter mornings. November and December is best.

Environmentalists must be right then, climate is not what it used to be...

@Jeremy: you might as well move to sunny Scotland during Winter  Wink

Isn't that the truth! Florian Look at the detail on the white fuselage! Cold crisp weather!

Heat Haze is worst when you get an area of concrete between you and your subject, if there is a taxyway or even a runway in front of you then the subject is behind that, kiss goodbye to your pictures...

Maybe a dumb question: Does wind have any influence on heat haze?

Yes it does Sleekjet. The more surface wind the better, on a day with heat haze.

What about humidity? Can that affect heat haze at all?

Hi everyone,what can cause heat haze in the wintertime even when it is below 32.I had that happened to me one winter day in Reno last year.It was 20 degrees.
