First of all many thanks for visit and comment :) It is nice to hear that you like this bat picture.
According to the close-up, the picture was taken from distance of some 4-5 cm. It was possible because I found this specimen (and also many others, as in this place some 1500 individuals of some 5-6 species can be found during winter period) on the wall some 60 cm above grond level (some of "channels" in this bunker is some 120 cm high).
Once again thank thanks for visit.
