There are a few tutorials for this in Photoshop and Illustrator, but I haven’t found any for the GIMP, so I attempted it myself! It is a fairly simple method and easily done with great results!

When wanting to combine two or more photographs for a higher dynamic range (HDR) or correcting an overexposed photograph, I mostly use programs like Photomatix, however it is sometimes too difficult or frustrating fiddling with the settings for minutes getting nowhere. So, there is an easier way and in certain cases much better than an HDR especially if you want to avoid those really surreal photographs – Digital Blending is the way to go, you can be much more selective with your increases/decreases in dynamic range and get more realistic results.

This is a very simple method to making photographs grungy, but its also a good technique to have handy in your mind for any post-processing you might do in the future!

This is a really simple tutorial and well worth the small effort required, because you’ll have something to put on your photographs/artworks without making it look too ugly while making sure you get enough credit in case your work is copied or used.
