D3200, D800, D4 - which image is which?

Here's a little fun exercise - click original, download the full image (12MP). Can you guess guess which image is from which camera.

Lens AF-S 70-200 2.8 VRII, tripod, exposure delay for D800,D4, timer for D3200, ADL on (auto for D800, D4), matrix metering, ISO 100. Zoom adjusted for approximately same field of view.

RAW, processed into DNGs by DXO Optics pro with only Lens softness, Unsharp mask, NR, CA (all defaults) only. Imported into Lightroom 4 same settings for everything except slight adjustment for exposure to even out the metering. Output as JPEG 80 quality downsampled to 4512 x 3000 (the M size for D3200)

Here is the image (small version) without pushing shadows or pulling highlights (it is a high DR image as light is from behind buildings):

And the final images, not in any order (I don't know, will have to check myself which is which) - EXIF stripped of course.
