Question

Luminosity & Darken mode

This post concerns a technique for 'flash-ambient' (or flambient) photography using a 'window pull' method to obtain good exterior views from a window:
 
I have three exposures of the same subject, these three exposures are opened in PS as layers: 
 
The base layer is an exposure using flash
 
The mid layer is an ambient exposure with the layer set to 'luminosity' mode and transparency set to 50%
 
The top layer is set to 'darken' mode with a 'hide-all' mask with the window view painted in using a 'normal' brush at 100% opacity.
 
When I change the transparency of the mid layer (the layer set to luminosity mode) to say 90%, the strength of the darken mode layer increases. If I set the mid layer to say 30% transparency, the strength of the darken mode decrease (see examples).
 
Could someone please explain why this is happening? I want the darken mode to be at 100% strength, no matter what transparency value I set the 'luminosity' layer to.

The obvious question is, how does the window look in the flash exposure? Is it darker than your masked layer 3? It sounds like it is.

No the flash is brighter than the masked layer.

Check the layer options. This has to do with the various advanced blending options like isolating blending in groups and all that. Same for the blending itself. A simple color overlay set to Darken can be more effective than creating extra layers due to the order in which this stuff is processed.

Can you be more specific please: which blending option is going to provide the desired result?
