Ambient occlusion trick with only Photoshop

Hi All,

Here I am going to share a trick which I use to incorporate, if not true ambient occlusion, but a nearly similar effect to kerkythea renders.
The first thing that is definitely required is Photoshop.
Now follow the steps very very minutely-

1. Open the render in photoshop. In the layer panel, make a duplicate layer.

2. Select the duplicate layer. Go to filters> others> hipass. Reduce the pixel to only 3. Click ok.

3. Got to image> adjustment> desaturate.

4. Now image> adjustment> Levels. Bring right INPUT LEVEL markers sliding to the middle, or may be a little more lower. Then slide the left marker upto almost same position to the right marker. (May be a bit gap). You can see the image has gone like- the darker/ shadow parts black and other part completely white.

5. Now set the opacity of this layer to 25%, and set the blending mode of this layer as MULTIPLY, and Voila !!! See the result. Save the final image in PNG. (Play a bit with final opacity to get best result.)

6. For advanced effect, in the last stage for the export layer, go to color management, and play a bit.

The point number 4 is most important. If at the 'literally middle' position does not do it, you may move the markers slightly to basically 'middle of the black shade distribution'.

The main thing is to achieve the target which is written in that point.

If requested, I can give another good post production trick to incorporate photo- realistic depth mapping (advanced usage of photoshop lense blur).
