I don't know the limitations of Photoshop LE, but in Photoshop, I would
create a new layer via copy (of the background layer), change to blend mode
"screen" and adjust opacity subjectively. Then add a layer mask and create a
gradient black at the bottom to white at the top.

The screen blend will lighten the whole image and the gradient mask will
prevent the lightening affect in proportion to how black the mask is.

I have a slide of a building (the treasury in Petra), lit only by candles
standing in front of it.  This means that the top half of the building is
much darker than the bottom.  While retaining this effect to some degree, I
would like to lighten the top of the building and leave the bottom as it is.

Is there some way I can use Photoshop to lighten the slide progressively
from say 0% at the bottom to 50% at the top ?

I have Photoshop LE 5.0, so I might be missing some of the more esoteric
tools.

Mike Bloor
