Orchid And Mirros set

please excuse my ignorance, but are these four different plates or four different prints from the same plate? or something different altogether?

Sorry for not clear descriptionThese are four different plates

no problem...i'm not skilled enough to know the difference...hard to choose, not that one has to...but i think the bottom left speaks to me the most of the four...it seems a little cloudy (mysterious) and somewhat vignetted...and i like the fact that the profile in the back is in shadow/is shadowed...it also seems to be slightly less in focus or to have a softer focus, which lends a nice moodiness to the overall image, i think. thanks so much for sharing these!
