I never thought that heat haze could blur my photos in winter conditions. And yet that's exactly what happens here. On clear March days temperature difference between night and day is easily over 20 degrees. Sunshine warms snow close to 0 degrees while the air a couple of metres higher is significantly colder. And as there was no wind air didn't mix so easily, creating good conditions for heat haze.
This is how Wikipedia describes heat haze: Convection causes the temperature of the air to vary, and the variation between the hot air at the surface of the road and the denser cool air above it creates a gradient in the refractive index of the air. This produces a blurred shimmering effect which affects the ability to resolve objects, the effect being increased when the image is magnified through a telescope or telephoto lens.

We know the reason why it's not too sharp but the capture itself is fine !
TFS and best regards

The two persons in the foreground are perfectly sharp and the haze in the distant part of the picture creates a very interesting and very attractive effect. The result becomes very artistic! This is, with or without the blur, a very pleasant daily life capture, this is really winter in the northern hemisphere.

Really an amazing effect here from heat alone, Kari. There's a great transition, happening even at the head of the person in the black and yellow jacket, that turns a sharp shot into a kind of impressionist painting! By the time we make it all the way back in the shot, that effect has taken over completely. The colors are great and the scene really quite impressive. Thanks!

The heat haze is so bizarre and so effective - as Andrew says like an impressionist painting. It is always great to see something quite different on Trekearth. Tfs, Marlene

the unusual phenomenon has created a most distinct shot,whilst there is nothing sharp this is a strong composition that has much interest and charm.
A really striking photograph,well done.
