"applying" a blend mode
hi.
i curious rules ps follows when comes merging of layers blend modes other "normal".
can direct me somewhere, can find information that? searched web extensively, couldn't find anything. adobe livedocs mute that, too.
for example:
- blend layer 2 (hard ligth)
- blend layer 1 (vivid light)
- background layer (normal)
--> if blend layer1+2, alter visible (flattened) on-screen-image.
another example:
i had layer landscape + medium-blue sky without stars. on layer had white stars on (nearly) black backdrop. used "lighten" mode fill medium-blue sky stars.
later on, did trick remove black backdrop , have pixels of white stars on layer. (and no, didn't "blend if" or "color range" or therelike, used blending modes!). unfortunately can't remember how did exactly, think merged layer empty layer (i know sounds weird), possibly putting both layers group first , merging group.
fact is, after merging (of stars layer , "???"), got layer mode "normal" , pixels had rgb , transparency values in such way produced same final (blended) picture - beforehand - pixels of white-stars-on-black-backdrop did in "lighten mode". if went , forth in history (before , after merging), there no visible difference in flat-on-screen-image.
i thankful, if - chance - knows had been doing :)
(i tried merging layer with, respectively, empty, black-filled, white-filled , 50%grey-filled layer, couldn't reproduce it).

the blend mode of top layer applied between layer , entire set of layers beneath it, if underlying layers had been merged conglomerate "substrate". see when deactivate top layer single pseudo-flattened layer (the substrate) top layer blend in mode assigned top layer when activated. blend modes of underlying layers not come play except affect substrate.
