Neutral Density Gradient Filter
How often does it happen that you end up with an image where the foreground is exposed correctly and the sky is to light because you have forgotten your filter set at home or don't have one
Well here is what you can do to remedy the situation...
(1) open your image in photoshop
(2) make sure the foreground colour is black
(3) Layer > New Fill Layer > Gradient > just click OK
(4) now the gradient fill dialogue box opens: tick at the bottom: reverse and align with layers
> DO NOT CLICK OK YET! > double click directly on the gradient in your dialogue window and it will open another dialogue window > now you will see "little" gradients at the top and one big black to transparent gradient at the bottom. Over the bottom one on the right hand side is a little white thingy that looks like a house on its head > click this one with your mouse and drag it to the left > let go of the mouse
to check your image: the black to transparent gradient that went all the way from the top to the bottom of your image should slowly lift towards the top. If it's not enough drag the little white "house" further to the left until it lines up nicely between sky and foreground. (Don't forget you have to let go of the mouse to see the difference!!!)
(5) click O.K. once happy and click O.K. again to close both dialogue windows > now you have two layers on top of each other. Make sure the top one is activated > set its blending mode to overlay
and you are done!Fine tuning
The effect is not strong enough for your taste? Click on the top layer and drag it to the bottom of your layers palette over the symbol next
to your rubbish bin to duplicate the layer. Now the effect might be too strong so just lower the opacity of that very top layer before flattening the whole thing.
Hope this is useful?
