This technique makes images eye catching and dramatic by giving them a gritty, grimy look. It is done in a more complicated way than just using a high ISO or adding fake grain.
b. The tools used to perform the technique
Brush tool, adjustment layers, blending modes, curves, image flatten, duplication, duplicate filter (ctrl+i) and filters (high pass).
c. Brief description of the processes involved
This technique basically involves blending an image with a duplicate that has been dramatically altered(using a 'high pass' filter). This is then repeated to further dramatise the effect. The colour is changed also using an adjustment layer and then slightly altered with a brush tool to make features such as eyes stand out. The image i used is one i took of my Pop.
Problems: This entire tutorial uses destructive editing techniques! Some tips for making this method non-destrucive are, of course, not flattening the image as the tutorial suggests. The point of flattening in this tutorial is so that an effect can be applied then reapplied for twice the effectiveness. Rather than doing this, a safe option is to simply apply one adjustment layer, then place another on top of the first. Also when using a brush, rather than just painting straight onto the image layer, create a transparent layer to paint onto.
d. Sample images (eg before and after versions of an image).

Conclusion: This is a very interesting effect. I am actually supprised how well it worked and that it was different to just adding grain. I think rather than just making the the entire image grainy, it accentuates the lines and features. It is not a technique i would use on all my photos but it is an interesting option for playing around with portraits.
