    He's certainly a willing model Brian

    What apertures were your two exposures?

    They were both F/14. Next time 2 & 4 with a F/8 & 14?

    I have yet to really understand any benefit in combining shots of two different apertures (assuming camera and focus is not moved).

    That said, two shots stack/combined should help reduce noise, but the same is true of two at f/14 or two at f/8.

    Therefore, the same should be true for the two different exposure times, although again, I'm not sure of the benefit beyond there being two shots unless you left ISO alone hence also bringing in an element of exposure bracketing.

    At least I can't see those extra legs in this crop

    But we know they're there. And both shots used ISO 100.

    Here's my thinking. The longer the exposure the greater the detail.
    with two significantly different exposure times there could be significantly different areas of detail as well as different light and dark.
    by depth merging them I could end up with a richer deeper shot...... or not.

    Brian you're getting some crazy stuff nowadays. I'll leave the detailed responses up to the macro/bug shooters. Nicely done.

    Did a little more investigating and found a Spider blog in Canada that had the answer. It is a "Hersiliidae (tree trunk spiders).'

    And your guess was right the extra legs are outrageously long spinnerets.

    I'm using Ansel Adams macro techniques that he developed for photographing Alaskan fauna. Very long exposure to capture details and the highest F/ that I can make work.
