I tried .dng raw for some images and when I shoot at the wide end the image is distorted (fisheye like) in the .dng image but the camera fixes the distortion in Canon Raw and jpeg images.  It's so bad I don't want to use CHDK .DNG.  I didn't see this on my SD990 .DNG images.  It's interesting how much the image is manipulated by the in camera image processor.  Too bad PSE can't import S100 Canon raw without first running Adobe conversion to .dng.

Hnikesch
I tested my number using the factory battery.  Maybe it is just different on every camera.  The ebay battery never worked well the battery percent I have now.
Hnikesch are you a programmer?

No just a shooter,  I am using all Canon batteries.  It's amazing to see what you guys have done on just over 2 months,  the SD900 & SD990 ports were a lot longer in process.  Great job

I found a back door to load Adobe Camera Raw 6.6 into SPE 9, the wonders of Google.  Now I can directly edit Canon S100 raw in PSE

I've loaded the latest version for the S100 (s100-101a-1.1.0-1916) and have the time lapse feature working. To save on battery, I'm trying to get the display to turn off between shots. I've tried "Ultra-intervalometer" and "Accurate Intervalometer with power-saving and pre-focus" but neither will turn off the display. I've read that I can plug in an HDMI cable, but I would think that would consume more battery if it is trying to drive an external monitor. Is that not the case? Is there some way to get the display to go off without having to use an HDMI cable?

If you look through old posts here you will find that the LCD backlight does not actually consume a lot of power compared to the rest of the camera electronics.  So don't expect much more than 10% - 20% battery life improvement with the backlight off.

Here's a link to a modified version of the default intervalometer script with code to turn off the backlight after each shot :

I'll take the 10-20%! Thanks for the link to the set_backlight code--it works great on my S100.

Here is intervalometer code with optional focus lock and adjustable delay before backlight goes off:

Code: [Select]
rem  Intervalometer with backlight control
rem  and focus lock. Note: focus lock happens
rem  not on first focus, but after the first
rem  shot and just before the backlight goes
rem  off. Adjustable delay before backlight
rem  goes off (b) allows time for lengthy
rem  post-shot activities like review. If
rem  none, b can be shortened to 1.

@title int_BLFL
@param a = interval (sec)
@default a 10
@param b = backlight delay (sec)
@default b 3
@param c = use focus lock? (1/0)
@default c 1
 
if get_mode = 0 then goto "in_rec"
  sleep 1000
  set_record 1

:wait_rec
  sleep 100
  if get_mode <> 0 then goto "wait_rec"

:in_rec
s = (a*1000)+get_tick_count
shoot
sleep b*1000
set_aflock c
set_backlight 0
do
    sleep 500
until (s <= get_tick_count)
do
    s = (a*1000)+get_tick_count
    shoot
    sleep b*1000
    set_backlight 0
    do
       sleep 500
    until (s <= get_tick_count)
until ( 0 )

:restore
    set_backlight 1
    set_aflock 0
    sleep 1000
    end

I've been following this thread and I am very impressed with the work accomplished

I apologize if this has been addressed or inappropriately placed, but has anyone been able to get a script to work allowing the flash ttl to function in M mode

I believe there has been a script bouncing around that would do this in the S95…but with the Digic processor change, it is doubtful that this would work

First, thank you to everyone who works on this.  I can't imagine getting started on this myself!

On the S100, when you go over a 1 second exposure, the ISO is forced to ISO 80.

Is there a way to change this via CHDK?  If yes, a pointer would be appreciated.  I have reviewed the ISO section in the menu but am not sure how to alter it to achieve this.

Thank you,
David

Yes, once you load the CHDK onto your camera hit the play button (alt) then menu.  This will take you into the CHDK Menu.  Go into Extra Photo Operations, there you can change the ISO Value manually (imput a value and a multiplier).  Make sure you change Disable Overides at the top as well.  While you are shooting it will tell you the ISO you're using in the top Left.

I think this is one of the best features of CHDK on the s100.

As a matter of interest what practical benefits have you seen from this and under what situations ?
