Help with setup

These two images shot with 30D+100mm macro f2.8. Setup was P mode into night sky using 580EXII Speedlite + 430EX coming from behind and below the spider

Tricky doing a spider in web with no background close by. I never use P mode- either use M mode for full flash shots or use Tv or Av modes for fill flash.

For M mode I would have set ISO100/200, F11, 1/200th and around -.66 FEC on the flash.
For Fill flash - Tv or Av and adjust ISo to give around F5.6- F8 at 1/200th. EC set at -.66 and flash at -1 FEC

This assume the flash is in ETTL mode

Many thanks Brian, I'll give that a try.

Should add I shoot RAW so do have a bit of latitude with exposure.

Wish I had this info to use my flash effectively for the following shot - without disturbing her.

Instead I captured her in ambient light (40W over the range lamp in the kitchen). She was hanging from a single string from under the hood over the range and was exceptionally quite (fortunately). I decided not to startle her - bring my 2220 explorer with all the rig pre-assembled. Inching forward very slowly to get enough of her in frame - and then a long exposure(74sec) on Av.

It moved one of its leg (left lower corner of the image/spider) very slightly once when I accidently breathed out during the exposure. You can see the same leg in two different but close positions.
