I've been following a tutorial on UDEMY called creating a 'Dragan Effect' which basically follows this path…base layer: Blend Mode Normal, 100% opacity. Levels Adjustment: Normal Mode, 100% opacity. Multiply Layer: Multiply Layer Blend Mode, 50% opacity. Light Bits: Overlay Blend mode, 100% opacity. Merged: Normal Blend Mode, 33% opacity. B&W: Saturation Blend mode, 100 & opacity. ~ After this the 'Merged Layer' is then moved down to just under the B&W layer. At this point, the tutor then reduces the Opacity in the B&W layer to re-introduce some colour again before going on to the next stage ~ however no matter how many times I've tried it, as soon as I try to reduce the B&W opacity nothing happens! No colour appears! and it now appears that no matter what I do on any yes, any layer nothing alters, nothing happens. It is an effect I'd like to master but now I'm wondering is there a bug in your system or is there something else I should be doing ~ failing all that how would you guys create the so-called Dragan Effect?
