Challenge has finished
Tone mapping has been a well-respected artistic tool at least since Ansel Adam's book "The Print" -- but it required a set of darkroom techniques that were difficult to master. Now tone mapping is possible in-camera using contrast and exposure settings, shadow adjustment, etc. Image editing software on a computer allows even more complex transformations: HDR (High Dynamic Range) processing, levels adjustments, retinex, dodge/burn, etc. The challenge here is to use tone mapping to make a photograph express your artistic vision rather than what the camera literally saw.

Here's an example of how you can show the transformation with before/after within one image. Between dirt on the plane window and atmospheric haze, color and contrast were gone. The transformation processing was done in GIMP: decompose to LAB, unsharp mask L, compose (improve sharpness); duplicate; uniform retinex and apply as soft light layer (restore colors); flatten; curves (fix tones); and finally GREYCstoration (noise reduction).
