S90 Porting Thread

Zooming should work, if you are using the latest build (V3). A normal behaviour is, when you are zooming back from digitalzoom, that zooming stops at 3.8X magnification (thats the border between digital/optical zoom). Simply release then the zoom key, and zoom then (using the same zoom key) again.

For AF in moviemode, you have to assign a AF-Key under "Video Parameters"->"AF Key" options (assign to SHUTTER of SET button).
An make sure that you are not in ALT mode if you are pressing the SHUTTER / SET button to refocus.

I will test that. I did have the AF key set to Shutter and I am sure I released the zoom out when digital zoom reached the point it hit optical zoom and then would not zoom back from there. Will retest though to make sure.

Also another issue wuth 4GB> cards.

If you take the card out and try to read it in a card reader it will only shows the furst partition so in order to extract the photos and videos you have to use SDM to swap the partitions, take it out, reinsert, copy of the files, swap partition and then put it back in the camera. PAIN!

That is a Windows limitation though (Oh God MS you suck!).

So the only other alternative is to use smaller SD cards or use a USB cable from the camera 🙁

I retested AF and Zoom function and it works fine on my camera. Also some other s90 chdk user reported that it is working, so i am pretty sure you will also get it work. 😀

You can also swap the partitions without windows/pc. Check the CHDK menu "Miscellaneous stuff". There is a option "Swap partitions" which will to the job. If you have partition 2 activ (the one with the pictures), chdk will of course not autoboot. Simply copy also the PS.FI2 build of chdk to the second partition. So if you start with the 2nd partition, you can use the Firmwareboot method to start CHDK, and swap then the Partitions back.

Hmm. I swear I had digital zoom with video recording. Maybe I am mistaken as it only appears as an option in the S90 menu using fully auto. Also AF whilst 'recording' video does not work no matter if a key is assigned (Shutter or set).

Just to make sure you understand. I would like to be able to AF whilst recording 'video'. AF and zoom for still photos works fine.

Also of note. If oyu enabled RAW in CHKDK it will say RAW is disabled whilst in photo modes. It does not matter since the RAW setting of the S90 overrides that setting it would seem but you won't get a DNG file. I think there are a lot of bugs to work through but this is a beta test version after all 😉

Swap partitions in the CHKDK menu does not work either. It says it only has one partition.

Oops! My bad. I had the 2GB card in not the 16GB. Ignore that last one 😉

If you have swapped the partition in camera it will not boot. You cannot have two boot partitions. So I would still have to use SDM to swap it back once read in the reader. Bit of a pain really but hey.

The other thing that is bothering me is that when you turn the S90 on it immediately goes to the CHKDK mode (Photo browsing mode). For speed in order to take a photo from startup it should go straight to camera mode. Not CHKDK. Pretty much every photographer wants to go stright to taking a photo. Unless there is an option I am missing?

ERR99

Which Firmware version do you have? I ask because i cant test other fw versions then 101a. You are the first one who reports serious problems with the current build.

The RAW disabled message occurs if you have canon RAW enabled, because its useless to shot canon AND chdk raw (saving to sd-card takes ages...) . So set back the camera to JPEG only shooting, then you can get CHDK RAWs (no DNGs).

deadman

Sorry 101c v3. I am gonna hold off using CHKDK for a while until it matures a bit. I was just curious to see how progress was going and reporting back on a few things I noticed. Sorry if I don't feel like being a 'proper' beta tester 😁

Nice work though I am well impressed. We need time lapse! Longer exposures (Dangerous in the sun lol) etc 😉

Of course you can boot CHDK on the S90 from the second partition, thats what i have written allready in my previous post. You have to use the manual PS.FI2 firmware boot methode (and not the diskboot.bin/autoboot) to start CHDK from the "big" (non boot) partition. Check the CHDK FAQ/Wiki to learn more about the firmware boot methode.

Starting into playmode is standard chdk behaviour. Simply hold the ON/OFF button until camera starts direct in to SHOOTING mode.

Thanks for the info. I will play some more some other time. Right now most of the functions are not what I expected or need right now. There are some functions like time lapse ect I am waiting (Hoping) for and AF whilst zooming and recording video if possible would be nice. Sorry if I do not reply after this post for a while. I will catchup in a few weeks time probably.

ERR99

Could please also other users of the V3 build 100c and 101c build test, if AF-scan and optical zoom in moviemode is working properly?

gsbergman

Build 100c optical zoom in movie mode is working. Not sure about the AF-Scan? I'll check it when I have time.

No, it's not the only other alternative, there is "Swap partitions" as ERR99 says, and Mac and Linux.

100c optical zoom works in video mode, but does not retract once you get into digital zoom. AF doesn't seem to work at all, unfortunately.

Oh and by the way... absolutely brilliant work you've done here! Many, many, many thanks 😀

Okay, on the 100c port i think i found the problem, the zoom_status variable was not correct.
But this problem was not present on the 101c port, so please could also 101c users test the AF&zoom overrides in moviemode.

Anyway, here is a new Build (V4).

Differences to V3:
- Corrected zoom_status for movimode (only 100c version, other was allready correct with V3).
- Enabled DNG support (experimental)
- Corrected game modes resolution
- Removed unsupported manual focus via zoom lever osd entry

The attached zip file, contains both versions (diskboot.bin and PS.FI2)

An here the V4 port for 101a fw version:

An finally the V4 build for cameras with 101c firmware:

Thanks! What's the advantage of DNG over the native CR2? With non-raw cameras it makes sense to have dng, but is there any reason to use that over the built-in raw format?

Sometimes canon limits the usage of RAW in the automatic SCENE programs, and allows only JPEG shooting in this modes. In this case CHDK RAW/DNG can help out. 😉 But in general you are right, there is no big need for CHDK RAWs/DNG on cameras like the S90/G11.

For what it is worth, SDM does not support CHDK raw on cameras that have native raw.

I do not think that will inconvenience many users.

The zoom now works properly on 100c. I'm not sure if the camera is supposed to have an AF feature in video mode. If it does, I'm not sure if it works.

I've tested some override features and so far, everything seems to work as it's supposed to. I've done a 8-minute night-sky exposure without problems, as well as tested extremely short shutter speeds, which seemed to work. Not sure if anyone really needs anything quicker than 1/10000, anyway, and that definitely worked.

As for aperture override: this depends on the zoom. If fully retracted, it doesn't go beyond F/8.0, but it can go up to F/16.0 when fully zoomed in. I didn't do any tests in-between, but I suppose that the maximum and minimum aperture change according to the lense's specifications.

ISO override didn't seem to have any effect outside the camera's range. So even if it said that the photo was taken with ISO 12 or ISO 64, the photo was basically exposed at ISO 80, and when taken with ISO 5000, the real ISO was still 3200.

What seems bugged to me are the games, though. Reversi seems alright, Sokoban doesn't start at all and the colors in Connect 4 and Mastermind seem unusual.

Oh, and another thing: the camera will not take a dark-frame if the normal exposure is below the limit. Meaning that if you set override to above 1.3 seconds, but the camera's setting is below that, it will skip the dark-frame.
