Image #1 is handheld at about 1.5:1 magnification; Image #2 on tripod at 1:1.
I put the spider back in his bush, he was pretty interesting looking. C&C welcome.

Nice, I've photographed a lot of these but never one that was white with red spines. Here in Houston, TX I see white with black spines.
'Middle of the Mitten' = St. Louis, Michigan?

Pretty dang good on your geography, St Louis, MI does bill itself as the Middle of the Mitten.
I live a little outside Grand Ledge about 40 miles South of there. I'm kicking back in Nokomis FL for a few more days right now, and that's where I found this spider.

This is your first post to the Macro Forum. Welcome!
If you want to pursue hand-held field macro-photography, this is the forum to learn about technique, equipment, and settings. What speedlight do you have available?

Thanks, Douglass, for the welcome and the kind comments. While this is my first post here, I have been subscribed for over a year and check-in almost daily. As to hand-held macro, Geeez that is humbling, my evf was like the Guess Who song "Shakin all over" Lol!
I have and used for both these shots a Yongnuo YN560IV w/ 8x12-inch softbox. I have no idea why the exif info would show otherwise as I set the flash to trigger in the menu. The only reason I set the shutter speed so long was so I could see to focus.
Thanks again and I only have a couple forthcoming questions, a couple thousand that is!

Your YN-560 IV has a mfr's listed GN of 39 at 35mm & ISO 100. Independent testing is closer to GN 34. Read more here: http://www.uglyhedgehog.com/t-208134-1.html
Yongnuo circuitry does not register on most cameras, so it is recorded as not used. The vast majority of macro-photographers set their speedlights manually, usually starting at 1/8-power at ISO 200 & f/16.
Shutter duration has nothing to do with focusing through the viewfinder. The flash duration is so short (approximately 1/5000-sec) that most camera and subject motion is frozen at shutter duration of 1/200-sec.
Does your speedlight have a flip-down plastic diffuser in front of flash lens? If so, this will set speedlight to widest coverage. Does your softbox have an internal white cloth diffuser that can be stretch from one side to the other? Both of these characteristics will improve light diffusion.

P.S. - Most M-Ps use a 6x8-inch softbox diffuser for field photography. We have found that large diffusers are too cumbersome around plants.

First off, thanks for the added info. I did set my flash manually, in this case full. I set up in shadow assuming f/16 at 1/3 second would have minimal impact on lighting due to flash being my major light source. through the evf at proper duration I had no light to focus with.
Will have to check on plastic diffuser. Softbox does not have internal cloth diffuser, will look into both. Large diffuser cumbersome? Well, that is close to the words I have used, though not entirely exact! Lol!
Thanks again for your help.

On the 6x8-inch diffusers, the internal white cloth diffuse is sewn & Velcro'd against one side. It must be physically stretched across internal space to a Velcro button on other side of diffuser.
Most speedlight have a slot above flash face that stores the plastic diffuser when not in use. Pulling diffuser out of slot, and dropping down across flash face will set speedlight to widest coverage. Storing plastic diffuser returns speedlight to normal use.

Thanks, a question though, your comment "shutter duration has nothing to do with focus" am I correct in assuming this is because you are using Nikon DSLR and I am seeing differently in my Sony A-77 evf? When my shutter duration was around 1/100" I had nothing but dark. Focus was manual.

You got me! I did not know that EVF meant 'Electronic ViewFinder'. As opposed to my DSLR optical viewfinder.
I have no idea why you must use a long shutter duration in order to have enough light to focus. Maybe you can learn something here: http://www.imaging-resource.com/PRODS/AA77/AA77A3.HTM
