As a joke number 2 is possible to consider the fact, that described "photographs" were created during flash illumination... Exactly the same like during photographing, but the energy of the flash is really somewhat larger - many orders of magnitude...
Kama idadi joke 2 inawezekana kuzingatia ukweli, kuwa ilivyoelezwa "picha" viliumbwa wakati flash kuja... Sawa kama wakati wa kupiga picha, lakini nishati ya flash ni kweli kiasi fulani kubwa - maagizo mengi ya kiwango...
