S100 porting thread

hnikesch

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.

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:

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 S95â€¦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 ?

Since the s100 auto sets the ISO to 80 stars and other real low light items do not show up well. The override makes very low light photography possible for example. It's better than post production on the computer. If your exposure is too long you get streaking stars (which might be desirable).

Matt

Edit: I uploaded a test video of the ISO override filming the stars to youtube Time Lapse Afghanistan Stars. It's not the best quality, but will demonstrate the potential capability of one aspect of CHDK.
Edit2: I'm sorry it put the video in here, I didn't mean for it to do that, but can't remove it without taking the link out.

Microfunguy

Thanks for that.

Can you explain what difference I am looking for ?

If you did not use override what would the difference be ?

I bet you get really clear skies there !

The Canon S100, unlike the S95, automatically sets the ISO to 80 when the exposure time goes over 1 second due to the CMOS sensor it has (most likely). If you were taking pictures of the night sky with an ISO of 80 there would be nothing besides blackness. With the manual override turned on with CHDK you can set up to I think 20000 or something rediculous like that. With higher ISO it will break out the dark objects without sacrificing an extremely long shutter speeds. You can also change shutter speed, aperature, etc overrides as well thanks to CHDK.

Hi,

first I want to thank all developers here who did a great job for porting the s100.
I saw (on http://chdk.wikia.com/wiki/For_Developers) that the color for the s100 turns from pink to green - yeah!

On http://chdk.wikia.com/wiki/S100 there is a link to the trunk:

>CHDK is available as an ALPHA version for the Powershot s100 with firmware versions 1.00D, 1.00E,and 1.01A from >http://www.mighty-hoernsche.de/trunk/

But if I click on it it just shows:

CHDK-SVN Autobuild Download

This is the development version of CHDK which is considered "Unstable"
For the stable release click here
Complete zips contain additional files like scipts, grids, language files, RBF fonts and curves
Small zips contain the bare DISKBOOT.bin and PS.FIR/PS.FI2

Camera FW Complete Small
Errors occured during this build! Old version available here

But neither under the link 'here' not the link 'Older versions...' a trunk for s100 can be found. 🙁

Could someone of the developers please check?

Thanks a lot!

the autobuild website is probably being updated since chdk stable version is going to change (trunk will become stable and heavy development will resume), you may need to wait a bit until everything is restored (and probably will find s100 in the 'stable' autobuilds)

That probably won't happen until next weekend. The build broke last night for other reasons related to fixing some weirdness in one of the Makefiles.

mr.burns

OK guys,

thanks for reply!

I really don't know if this is the right place to ask this but I assumed this was the right place. I am really sorry if im wrong. 😉

I don't want to push or anything, just wondering as I have the S100 with firmware 1.01B. And there's no CHDK for 1.01B available yet. Is there already development on 1.01B? I saw it was already dumped here July 02. 😀

I can understand your concern - its frustrating when you want to play with something like CHDK and it just not available for your firmware version. Sometimes the original person who did the port will convert for another version. But otherwise, you're kind of stuck until somebody with the right skills who typically owns the same camera comes along.

In general, if somebody is working a port (or a firmware conversion) they post in the porting thread - so you are looking in the right place.

Incidentally, did you try the 1.01a version to see if it will work on your 1.01b camera ?
