That black tarantula is a species that is not known to occur in Singapore (Selenocosmia sp./S. javanensis; the only known extant tarantula species in Singapore now is the common, small brown Phlogiellus inermis) - were these pictures taken in Singapore or elsewhere? It would be very interesting if they were, from a taxonomic standpoint. Brilliant shots, by the way.
I changed my setup to go lighter.
Canon 60mm macro lens, Raynox DCR-250 and single Speedlite 270 exII with DIY diffuser from Victor, my good neighbour.
