Winter or not!

Nice composition Laurent. Only nit is the curvature of the horizon line. Is that a wide-angle lens thing?

Thank you for looking in and for the appreciation.I usually use my 10-20mm WA on these dunes but this one is with an 18-135mm used at the short end;I have noticed this curvature on other shots where my horizon is at infinity like here;unusual or normal?

I think is normal on large space where horizon line is seen,at last depend of each one taste how accept or not this,with WA lenses I saw indeed on vertical line subject ,that are not on center of image, this distorting effect.

There must be a focal length at which the curvature is barely or non-noticeable,a matter that our fellow member Mike Palermiti would surely explain.Your observation on WA lense distortion of off-centered objects is correct and I like to use it to give exagerated deformation to high subjects like churches and lighthouses as you have surely noticed.
