b) Sharpening with two polygons together: select portion of picture you want to manipulate using the Lasso tool >> then go to filter >> select blur>> select Gaussian blur >> change Radius to 0.4 or 0.5 ((what this does it interpolates the different folds in the edges)) >> Next select Noise (under filter) >> choose add noise >>Under distribution select Gaussian and change amount to 0.3

c) Curves: Go to Image >> select adjustments >> curves >> to change levels at two different points of picture, make sure setting is under default >> select spot on image (i.e.: in class sky) and second point on ie: land (class example) Now you can change the levels (Note: If you bring both ends to its opposite ends picture will change to negative state) use hand selector - select spot in image and move dot on curve to move - have two end points divides each section ( use on actual picture layer) OR: use lasso tool and select whole sky and while selected portion go to curves and move!
