Can others edit my Photos
Photos OK to edit
G'day all

Out in the sun today - somewhere around 30C in the shade ... add more for out-in-the-sun - and as I swept the lens across the scenery I noticed the heat shimmers showing up clearly on the buildings across the town



As always, feedback welcome

I find this one inspiring. I was always a bit cranky when the heat "ruins" a photo but this is actually cool in the heat.
 
Interesting shot Mr... in the shades still to dam hot. Still, shades a good thing when it is...
 
That's interesting, good catch.
 
Interesting photo! I've been told that if you take multiple shots through air like this, some can turn out much sharper than others because the shimmer effect waxes and wanes.
 
I have heard one of the reasons Canon's luxury lenses are white is to reduce the effect of heat on them. I think the other is marketing.
This looks a bit like some watercolors. :)

White lenses absorb less heat from the sun and that keeps them cooler when they are in the sun. We want to avoid getting the lens hot. Lubricants can run and components will expand which can alter the exact spacing of the elements, reducing IQ.

It could help their marketing too.

Of course heat shimmer in the air is something entirely different. It typically occurs far from the lens. A white lens can't help with that.

But some recent reports suggest that a lens hood can trap warm air and create local heat waves causing blurriness. A white lens hood might suffer less from this.
 
Very creative!

Yes, I am aware.
 
G'day all

Thanks for the feedback ....
and I forgot in my OP to mention that I was shooting at max zoom - 24x = 435mm dSLR / 600mm FFequiv

I'll need to remember the lens cap. I had some photos from a recent trip that were all "fuzzy" except for a few. I told my wife it had to be the heated air effect through the distance.
