This image was an experiment I did back in July to see just how far the 1D X files could be pushed.https://skydrive.live.com/?cid=335e18a4c22a5621&id=335E18A4C22A5621%21166
The photo was underexposed by at least 5 stops on a cloudy day and then pushed to the absolute maximum (+10.0 exposure) by Adobe Photoshop Lightroom 4.1. A little bit of noise adjustment was then made. But no curves, or any other fancy manipulation was done.
Enjoy the killer... the 1D X!!
Update: Same scenario, overexposed by 3 stops. Pulled to match the previous image.https://skydrive.live.com/?cid=335e18a4c22a5621&id=335E18A4C22A5621%21167
The underexposed photo was at 1/1250th of a second.
The overexposed photo was at 1/5th of a second.
0 stops: 1/5th (pretend like this is ISO 100)
1/3 stop: 1/8th (iso 125)
2/3 stop: 1/16th (iso 160)
1 2/3 stop:: 1/32nd (iso 320)
2 2/3 stops: 1/64th (iso 640)
3 2/3 stops: 1/125th (iso 1250)
4 2/3 stops: 1/250th (iso 2500)
5 2/3 stops: 1/500th (iso 5000)
6 2/3 stops: 1/1000th (iso 10,000)
7 stops: 1/1250th (iso 12,800)
And the photo itself has several more stops of dynamic range in it.
Cool thing is the comparison with the ISO. Basically, this camera can take a single photo and capture an effective range of exposures as if multiple photos were taken ranging from ISO 100 to ISO 12,800.
