    Huh. Are these named analogously? Or is there enough in common in our shared evolutionary history that the structures are homologous? (Even the patella?)

    These are NOT homologous at all — arthropod limbs and vertebrate limbs have completely different origins. It’s kind of a peeve for me that they’re given the same names, although it does make remembering them much easier.

    Huh. Funny thing. I had insomnia last night, and while I was sitting around letting my mind wander, I started thinking about spider photos (that part is your fault). Then I remembered there was a nice big web on my porch (one of those geometric jobbies). So I had to go look at it.

    I fetched my flashlight and found in the pitch black that if you lit the web from low and behind at a raking angle it showed up nicely. I figured if the spider was out, it would have made a nice Halloween shot in high contrast black and white with long shadows.

    Now I see I wasn’t far off.

    I need a mnemonic.
    Could their fly pants take more time?
    Credible triangles fire pies tinted most tarlike?
    Come talk for pennies to mensa teachers?

    The second one is random, but it has the benefit of getting Tr, Ti, and Ta lined up.

    That is a nice picture! 👍
    If you wish to (and this is optional), you can increase depth of focus by changing the aperture from f/8 –> f/11. You can get ~ the same exposure by increasing the power of the external flash by the same number of ‘stops’ as you did to change the aperture. It’s nice how these various settings compensate for each other like that. Alternatively, you would get the same exposure by slowing the shutter speed by the same number of stops, but if this is handheld then that might introduce camera shake.
    Focus on the nearby legs, and let the increased depth of focus get ya the rest of the body.
