  1. That focus stacking gives some amazing DOF on this. Great image!

  2. I always know better than to click on links, especially from photographers, that reference spiders ;)

    An actual hobo spider, eh? (a bit dangerous, aren’t they?) I’ve seen spiders that are very very similar looking but I’m not sure I’ve seen the real deal.

    Either way, I may have to give focus stacking a go here with my macro lens… though probably not with a hobo spider ;)

  3. Yeah, focus stacking is a riot of fun.

    As far as working with the hobo spider, yeah… they *are* poisonous and the bite is horrible. I cooled this guy down in the refrigerator for a couple of hours, then put him in a petri dish in the lab on top of a iced gel pack. All handling was done with gloves.

    When we were done, his reward for participating in the photo-shoot was getting released in the foothills behind the medical center.

  4. I believe this is a grass spider. Here is a guide to help distinguish from similar spiders: https://extension.usu.edu/files/publications/factsheet/hobo-spiders-key07-08.pdf

    Also here is just one source to clear the hobo’s name concerning medical significance, from the Journal of Medical Entomology: http://www.bioone.org/doi/abs/10.1603/ME09224
