POLL: Which missing features would you like to see?

[fudgey]

I'd like to have the possibility to attach a external numeric keypad to the usb port of G9 and control manual focus, zoom, shoot, aperture, shutter time, etc. Would be nice the possibility to configure the functions associated with buttons. This idea was implemented in the stopmotion software above...

The only way for you to achieve this is to build a customized keypad that does things similar to other supply voltage toggling CHDK remotes, since we don't have enough control over the port to properly communicate via USB.

Hi, i don't know if it was requested earlier:

- The ability to adjust/finetune the factory-settings in all programm-modes, including video.
   (Exposure/Brightnesscontrol of the basic settings)

For example:
My CANON SX200 IS produces in all Camera settings (Auto, P and Video) slightly overexposed pictures/videos.

If i dont change the exposure setting manually, the brightness will be adjusting automatically if i point to a new motive (brighter or darker than the former one) but still, this autoadjusting of the camera produces too bright pictures. Even in Auto mode!

If i change the exposure setting manually (-1/3 or -2/3 on Camera) i loose the automatic brightness adjust feature when i change the motive (i.E. from shadow forrest to sunny snow-fields) .

Therefore it would be great, if it is possible to finetune the basic settings (exposure globally -1/3), so that the automatic brightness adjusting is still present. Especially in the video mode.

It would be great to implement this feature to chdk

CHDK hasn't been ported to sx200is yet at all, has it?

About 14 firmware subs already have ev compensation control in video mode in CHDK according to `grep CAM_EV_IN_VIDEO include/camera.h`. If I'm not mistaken, adding video mode Ev compensation to other models is not trivial (because ExpCtrlTool_StopContiAE is used and it or its equivalent probably hasn't been found in most cameras, maybe not in dryos at all, I didn't check that deep and can't remember).

But adding Ev override in still shooting mode should be fairly trivial because I believe it only requires a single propcase to be set at a suitable time before autoexposure (although I guess this would be even easier to add to our existing exposure overrides to control a single parameter, most typically Tv, but that's not ideal and not quite what you're asking for either as in Tv mode you wouldn't be getting the Tv you're asking for with this fake Ev compensation active).

The way I use my camera (only P, Av, M, Tv modes, never any of those scene modes that mostly limit control of some parameters I like to have total control over even if I may make a poorer choice), I only have 4 shooting modes for which the camera may (or may not... can't recall how mine operates) remember it's own ev compensation setting, so I can guess why nobody's implemented it yet (or has it?). One thing to keep in mind is that we don't have many shortcut keys available (and the ones we have still aren't user customizable). What I mean is that if you enable this Ev compensation override, you'd have to go to depths of the CHDK menu (probably you'd want to put it in your user menu) to tweak it for each and every shot that needs it... unless the feature is implemented to only override when camera's UI shows Ev compensation of 0, for instance... but this would make the feature pretty hard to grasp since it's operation would seem erratic to someone who doesn't read the documentation or forgets.

But isn't the quickest way for you to fix this just to set your camera to -1/3 or -2/3 for each and every shooting mode and it'll remember it? Or did I understand something incorrectly?

There is one thing why ev compensation override would be somewhat useful... that's because the ev compensation propcase actually goes from -4 to +4 full stops, when the camera only lets you set from -2 to +2 (we can do this trick from scripts already, but it's really not very convenient for still shots to have to run a script before each and every shot... but then again how often do you need Ev compensation that huge).

How about an option to turn off in-camera noise reduction for JPEG files instead of being forced to use RAW to avoid this "feature"? Or maybe a way to control the amount of NR that is applied to the image? Don't know if it's possible but might be interesting to see who thinks it would be a useful feature.

The "Noise reduction" ("Dark frame subtraction" in newer CHDK versions) is a generell setting; although it is placed in the CHDK RAW menu, this overwrite is for all images, also for JPG files.
The Dark frame subtraction is done by the original Canon firmware, CHDK just overrides the threshold value...

I assume lightfusegetaway is asking about the actual noise reduction the canon FW does, especially at high ISO.

Right, the noise reduction used for any exposures below 1 second and at higher ISO. I almost prefer the noise "grain" over loss of detail.

I beleive the poll item: "Save RAW in DNG format (similar to previous request)." has now been done and can be crossed off the list?

I would love to see it replaced with "Save 1+hour of audio using existing onboard codecs". The feature I really miss from my Pentax Optio S4 is that you can hold doen the power button for 2 seconds, then it goes into audio mode. Then you can hit the shutter and it will record till battery runs out - with display off that can be hours! It is so super handy for recording lectures or presentations or meetings. Sure, the onboard mic and the audio quality (8khz PCM) are not great, but for recording voice conversations it doesn't matter, and hey - I have a Dictaphone/voice recorder in my pocket! Not all that many MP3 players have this option - at least not the MP3 players I know/own, so it is not simply a matter of "use a more apprproate/readily available device". And the clincher is that my Canon camera can already record audio, but the voice memo is cut off at 30 seconds, and the video comes with much larger file sizes and battery drain. So surely it would not be hard to extend the voice memo length, or make an option to record video at is 1x1 pixels and is black.

NOTE: I have fleshed out this idea in a new thread at http://chdk.setepontos.com/index.php/topic,4227.0.html

or make an option to record video at is 1x1 pixels and is black.

Note that you can actually get quite close to this with the video compression overrides on many CHDK cameras. In my testing (on an A540) ISTR the AVI file was only about 2x the size of the audio channel as a WAV.

I would like something to display the color temperature/white balance point that is being used.  So I can select a gel to make the flash match it exactly.

On many forums, photographers have been crying about "exosure to the right", a kind of light measuring, which would ensure that, no matter what, no channels are oversexposed (or very small percentage of pixels). Wondering why this feature didn't find it's place in this "wish list" since start of this thread

So we have a histogram which reports if highlights are blown with red dot, we have a possibility to control exposure compensation, I think nothing more is needed except a simple loop in the code (well, almost) ....

[shaltzman]

Hello
I don't find any answer on forum, sorry if there's.
Is it possible to have several flashes for one picture?
Is it possible to save a manual white balance setting?

I think these options could be great and could have a lot of different practice uses.

CHDKly yours ; )

(exif) data store: save a simple text file after every shot with additional informations

Hope its not too late, but here is a script I wrote that does this:
might need a bit of cleaning, look at the main

60i@720, 24p movie modes,double exposure settings,and maybe some kind of blue tooth dohickey coming out of usb or A/V out in camera so with a blue tooth usb in your computer or tv, photos would be seen immeadiately on your computer/tv up to 100 feet away, while i'm at it, wireless hdmi

Hi
I'm wondering, is possible to set external flash with shutter speed faster then 1/250s, im using SX10 and trying to do this from a long time, with internal flash it's working fine, i can take a photo at 1/10000 with flash, but with external flash shutter override doesn't work, and sets shutter speed automatic  to 1/250.
If is possible to do it, i want to see this feature in chdk
