How to get Rid of Heat Simmer in your landscapes.
« on: July 25, 2014, 05:44:37 PM »
I discovered something really cool today. I was shooting some Fracking platforms and noticed how bad the heat shimmer is here during the summer. Unfortunately, a Daytime shot was required and the simmer was making it difficult to use longer lenses to flatten the subject against the sky.

But I popped on my Big stopper and immediately noticed the simmer went nearly completely away on long exposures. Which I didn't think about before but was really cool to know now. I wish this is very helpful to other photographers who need to get past the daytime simmer.

Heres an example. Left is at 1/40 and the right is @ 30 seconds. Simmer be gone.

Nice tip, thanks!

On the negative side, you loose definition in the US flag.
What a mess, my camera's sensor is full of massless particules that keep on trying to behave like waves!

Note to self:  Tuck that one in a grey cell somewhere.

I'd probably do better to invest more time and less money.

Thanks for the tip. As you said, it makes sense after learning about it.

Thanks for sharing your observations!

Years ago I observed that 1/400 second gave me much more detail than 1/30 second exp time - o.k., I had some shimmer showing regions of much detail, some regions blurred but the impression was as sharper image overall. 1/30 second integrated sharp and blurred regions into a mushy overall experience. But I have NOT tried to exaggerate exp time beyond a second.
Focal length was 640mm equiv. - I set my 40D to ISO 1600 to reduce exp time despite ISO 1600 for a 40D is its outer limit quality wise.

Your example shows - IMO - the same detail in both shots but the 30 second shot is undistorted which makes it more attractive. One remark: The left shot seems to be in full sunlight, the right shot doesn't show the bright contrasty light - was that caused by the 30 second exposure or did you have changing light?

Thanks again - Michael

If I understand correctly, the long exposure here gets rid of random movements due to the heat shimmer. Similarly long exposures get rid of people when shooting a building. How would a CPL help? (I know how it cuts down haze and reflections, I mean how would it help in this specific instance). Adding it will be beneficial, obviously.

The light did shift during the Long exposure and the crops I posted were Unedited. Here was after few edits in and you can see the Long exposure has less contrast from the shifting sky. I did use a polarizer on both shots.

Now you just need to photoshop the clouds from the first image (short exposure) into the second one (long exposure).
