Ok. This is what I want to do:

Divide an image in a layer into TEN parts (ten new layers) each layer at a different density i.e. an image that originally had 255 shades would be layered such as the first layer would be 0 to 25 with it’s edges sharp. The next would be 26 to 50 with its edges feathered by 5 to 10 pixels. Etc etc etc until the final group would contain the odd group, it’s edges also feathered.

There would be ten layers. Each layer would contain its portion of the grayscale. I.E.
the first layer would contain dark shadows (0 to 25) the next group would contain lighter shadows 26 to 50 ETC till the final group would contain highlights 225 thru 255 all of them stacked one ontop of the other would reveal the final photo.

Thank you all for putting up with me.

Weird. Okay…

Put the image on a layer. Create a white layer. Put it beneath the image layer.

Duplicate the image layer 9 times, so you have a white layer, then 10 copies of the image stacked on top of each other.

Go to the bottom image layer, and using the Layer Options flyout menu from the Layers palette, set its Hilight to whatever you like–say, 230.

Go to the next layer up, use Layer Options to set its hilight and shadow appropriately. And so on.

To blend the layers smoothly, hold down Option (PC: Alt) ont he keyboard and split the setting triangles apart; if you set the Hilight slider, for example, to 125-129, it will blend values between 125 and 129 into the underlying layer.
