S90 Porting Thread

[MauricioRPP]

there are some timelapse scripts for you to download here on the forum. I use a simpler one because I do not shoot on the day to night transition, but you can find some that will change speed/iso/aperture for you.

I tried one old script (MDFB-080914) that does motion detection, and it worked flawlessly. The script for HDR posted earlier on this topic also works. The S90 seems to be very friendly to scripts, so grab anyone for time-lapse and try it.

Yes I've tried the Ultra Intervalometer time lapse scripts and they work great for light that doesn't change too much for example daylight. 

But the one problem with these scripts is that when the light changes you have to stop and adjust the exposure to try and prevent flicker during playback.  Of course you can use MSU Deflicker which does help but having a script that "bulb ramps" pretty much eliminates all the flicker making the footage look ultra smooth.

Any further suggestion appreciated.

Thanks...Cheers.

Hollywood, I rememer one bulb script somewhere here... do a search on the wiki or the forum, maybe you will find it. Lets not change the focus of this thread about the S90 too much

ERR99, were you able to check the "make card bootable" option??

[rirethy]

For perl script, i will post it, but I have no much time to clean it.

Hello,

I had some time, so, here is a version of my script.
It first checks the file system version (NTFS/FAT12/FAT16/FAT32). If it's FAT12 or Fat16, then the script is ready to write "BOOTDISK" at the right place. To really write on your sd-card, un-comment the line 198

Hope it will help.

and a few pages back there was a guy that had one great idea: to have the ability to manually control the focus while recording video. this would be heaven! not just autofocus, but intentionally shift the focus away. but I don't know if this is even remotely possible...

This is from http://chdk.wikia.com/wiki/CHDK_firmware_usage, but I just tried it, and it doesn't seem to work.  Does it work for anyone?

"S-series: Holding down the MF button (while in manual focus mode) allows use of the zoom-rocker for manual focus just as if you were using the up and down buttons to focus. Releasing the MF button allows the zoom-rocker to function normally.::::Select which button is used to enter <ALT> mode. Can be shortcut, flash, timer, iso or video. A short press of your selected button enters/exits <ALT> mode, a slightly longer press to use the button's normal function.
(S2 IS and S3 IS only)
Use the zoom-rocker switch for adjusting focus in manual focus mode."

Bug in Chdk ver 9.9.5.

Extra photo options.
Disable Overrides. 
Manual says use the "half press" plus (down) arrow to toggle overrides on or off.  Down arrow does not work.  What does work is the half press plus the (right) arrow.  I wondered what in the He$$ I was doing wrong or missing in order to get this thing to work, and via experiment, I figured out that the right arrow push will toggle the settings on or off...not the down arrow.  I changed this in the wiki user manual online, but now I am wondering if it is a user manual error or a s90 beta build firmware error.  Someone let me know please or just fix the issue...either way....
My guess is for every 1 user who tries chkd and actually understands what it does, there is 5 who just walk away because of poor documentation.  Come on guys...example:  set this factor to 1-10, if this factor is set to 1/2 to 1/16000, based on the ev of the tv and the iso, but only if the master is set to override the TV mode if setting 46 is positive.  translation....blah, blah, blah, blah, blah.

Yup...I was venting...
But what I was referring to is on page 8 of the Manual. 
Section: Extra Photo Operations- Disable Overrides. 
I had set this to "on".  Then per the manual, I should be able to do a half press + Down to toggle the settings on or off.  The down arrow did nothing, only the half press plus right arrow seemed to work.  Maybe I am missing something. 

Not to worry, I may not even bother with the program.  It seems more work then it is worth.  (No disrespect meant).

hi. very new to chdk. here's my situation, and related questions/issues:

my only disappointment with the s90 is the shutter lag, specifically the time it takes from the half press on the shutter to the time the picture shows up on the lcd. in auto mode, it was disappointing to see it so slow compared to my 3 yr old sd750. to my surprise, i found out the low light mode is SUPER fast.

so my intention is to use the low light mode as my main mode, so to speak. the only disadvantage would be a slight drop in pic quality, with the higher iso. enter chdk. i've had almost a week's worth of playing with it, so here are some stumpers - and reyalp thinks they might be bugs...AGAIN, ALL OF THESE IN LOW LIGHT MODE ONLY.

1. i realized (in low light mode) when i half press the shutter, i see the iso values on the lower right corner of the lcd do something curious: upon the half-press, it shows the override value i have set in shdk. and then it reverts to the iso value the camera assigns as it refocuses or whatever. that gave me an idea - i go into the menu portion, and thought maybe i can disable that - so i tried disabling servo af. it works. BUT - is that how it was intended - servo af MUST be off?

2. i set iso, but it's a little 'off.' if i set it to 50, the shot is taken at 80. at 100, it takes the shot at 160. it's exactly 60% more. why is that?

3. is there any way to override the zoom capability in low lightmode?

4. is it possible to override the picture size?

5. is it possible to have a forced flash?

THANK YOU !!!!

I will do tests checking what you asked on my S90, but I believe that the answer to question 4 is "no" already. The low-light mode is tied to low-res sized pictures.

Just wanted to thank you again for porting CHDK to the S90.

Are there any plans to port the latest changes (e.g. "Lock jogdial" & "Lock keys") to the Autobuild?

Thanks a million!

[c10ud]

does set_focus work for this camera? (lua) i wanted to achieve infinite focus with that method but that doesn't seem working here, unlike the built-in manual focus

[c10ud]

ok i wanted to do focus to infinity but seems like set_focus(65535) is too much, set_focus(16000) seems doing the trick though

[Hollywood]

Quick question, will any of the ports of the S90 work with the new S95 since I've read the only difference is the HD video and a few extra scene selection modes and the HS.

Any info greatly appreciated.

Thanks.
