I have been working on some ancient Indian temple environments for a new series of images I am working on. Architectural details on ancient structures can be really hard to get looking right as the result needs to be more organic and often more detailed. This is a result of many experiements on texture mapping and displacement.
Finally managed to get some decent results using a combination of image level adjustments and masking in PhotoShop with some ZBrush scultping to extract the motif details with a bit of CrazyBump to extract normal maps. Below are the different maps used to get the above result.
