This is an image photographed at the Battleship NC, a world war II ship opened to the public, on the deck below the main deck. The room light was a shop type fluorescent light which created a dramatic difference between bright and shadow areas. I had to shoot seven exposures on a sturdy tripod to cover detail in all areas between brights and darks to digitally blend them in photoshop to recover detail in brights and darks for a normal overall exposure using Luminosity Masks. (I first photographed the Checker Passport for white balance and camera profile.)

This is a five segment tutorial:

1. Prepare images for blending.
2.  Working on brights.
3. Working on darks.
4. One more bright.
5. Finishing adjustments.
