Using Photoshop's layers and transparency controls, you can create 'digital filters' that act as tints to add FX, or enhance an image. With some imagination and experimenting on your part, you'll be able to have an unlimited number of digital filters at your disposal.

Original Image on a layer, then create an empty layer above it for all these examples.. |
|
Desaturate - takes away all color, while still leaving the image in color mode rather than Grayscale. Grayscale will limit the types of filters you can use and FX you can do. Make a copy layer of your original image, and desaturate it. The desaturated image will be used in all these examples. |

Sepia Toned - Make your new layer active, and Desaturate this layer only. This can be done by choosing a brownish color: R-172, G-141, B-65 in the color palette. Use Bucket Fill to fill the layer above your image, than adjust the Opacity to 25%. Experiment with different browns or golds and the opacity settings to get different effects. |
|
Bromine Toned - In B&W photography, there is a process that adds a blue cast to your image. Make a new layer above your image, bucket fill it with blue: R-0, G-0, B-255, and adjust the opacity to 5%. |
|
Digital Snow - Apply this effect after you've resized your image. Bucket fill the layer above your image with white, set the opacity to 5%, then choose Dissolve from the drop down layer options menu in the layers palette. |

Digital Snow 2 - The same thing, just in color |
|
Using a Gradient can have nice effects. The gray here darkens the sky, and the yellow adds warmth to the ground foliage. The opacity here was set to 25%. See my tutorial on Using The Gradient Tool. |
