Successful experiment!

Thank you Perkin-warbeck!

This is an example of multiple exposures done in photoshop: four regular photos layered into one file. The blending mode that corresponds most closely to in-camera multiple exposures is the screen blending mode, but for that to look right you have to underexpose each individual shot accordingly, just like when doing it in-camera. As the source images were exposed normally in this case, I added an exposure adjustment layer set to -3 for each individual image layer (in theory should be 1/4 the exposure = -2, as I have four layers set to screen blending mode). Finally, I increased the contrast with a curves adjustment layer (just like in-camera multiple exposures decrease contrast, so do multiple exposures in photoshop).

I also tried to mimic the in-camera multiple exposure I posted a day earlier , but couldn't make it look as nice with source images taken from similar angles. But, with these four closer up source images, it worked OK.

I don't believe I could tell the difference between this and in-camera result. Both are great. I prefer in-camera though. Probably because of composition and softer overall effect.

Thank you Dorota!

That's the thing: I was not able to create the same painterly softness in photoshop as I got in-camera. The blending and gradation of the colors just seem softer and with a finer gradation in the in-camera version, while the photoshop version was full of "spikes" in the histogram (hmm, perhaps I should try it in 16-bit color mode?).

This sharper impression worked better in this image, due to the nature of the subject (less organic and more man made structures).
