This is a simple filter for Photoshop which changes colors‘ contrast as if viewed through colored glass, but without tinting the image.
Now a dramatic contrast effect once only possible in black-and-white photography can be done in digital color.
What?
Imagine you want to use black-and-white film to take a spooky picture of a landscape. You could make the sky unnaturally dark by placing a yellow glass filter over the lens; this will make the blue sky very dark, while the appearance of the green landscape is affected very little.
It would be fun to do the same effect in color. But the yellow filter will of course make the picture yellowish. How can you get the contrast effect without the colorization?
Vitriol will do it. Drop it into your plug-ins folder and start Photoshop. Set the foreground color to the color of the imaginary colored glass, and choose Vitriol from the Filter menu, under the sub-menu ‘Flaming Pear’.
Vitriol automatically provides density correction, so you can use a strongly colored filter without making your picture go dark.
Etc.
