TTL On-Off Script for M (CHDK) with S100

[RESCUEDIVER]

Any one notice that the shutter setting doubles when the shutter/focus button is half pressed...I just noticed this

I've checked CHDK settings and nothing is set to over ride

Sometimes this happens with a -1/3 ev when you focus far away and the Ev is less than -2
No idea what creates the problem but it never happened to me underwater

Thanks...the ev is -2

I haven't used the script underwater...just came back from a trip where I used tv and over rode settings in CHDK...took a couple of dives before I found a good relationship...some of the early dives even at ISO 100, 125 and 4.0 were slightly underexposed with ttl S&S strobe..nothing that raw manipulation didn't fix

It didn't hit me until after the second dive that the S100 even at 28mm was still considerably wider than my old SP350 set up...so I had to adjust my body to target distance and focal length...I hardly used the WA lens after the second day as 24mm negated the need...no big wrecks or structures

Need more practice...good excuse for another trip

At 24mm you have horrible pincushion distortion if look at the edges you will notice it
Or at least I do

You are correct...better at 28mm. WA lens had to be set at 28mm and still had a very minor amount of vignetting (mistakenly had at 24 for some shots...the Fisheye web page doesn't do justice on how bad that worked).

I was too comfortable keeping the camera at it's widest when I used my old rig (equiv of 38mm) ....need to be more careful using this setup

Now that CHDK is available for the S100 FW 1.02 I need some help. I've got it installed and working but I can't find the TTL settings for manual mode or for that matter TTL over ride controls in Tv or Av. Can someone point me to where the menus are please?

Thank you!
