Hack your Cannon

Your camera, pervert, your Cannon camera.

Quote:

If you're using a consumer grade point-and-shoot Canon digital camera, you've got hardware in hand that can support advanced features way beyond what shipped in the box. With the help of a free, open source project called CHDK, you can get features like RAW shooting mode, live RGB histograms, motion-detection, time-lapse, and even games on your existing camera. Let's transform your point-and-shoot into a super camera just by adding a little special sauce to its firmware.

Damn.
I've been catching up on all the posts made while I was sleeping.
This was at the top of the list.
Glancing at it, I thought it was "Hack Your Canyon" and have been looking forward to it.

I'm sure the reality of it is much more exciting for those who have a Canon of course!

Sweet. I have one of these.

Cicero · 05-31-2008, 09:52 AM

I've got one!! Now I need to go get batteries! Can I use this thread to take some photos with my enhanced features when I get them?!?

How exciting! (if you remember I've been complaining about my choice of camera since I got it) This puts a whole new spin on things.

Mine (Canon PowerShot SD950 IS Digital ELPH) does not seem to be supported. I wonder what would happen if I used the file for a different model?

Probably something bad. But...

Cicero · 05-31-2008, 11:41 AM

oh it isn't happening yet, but it's being worked on! At least there is hope HLJ!

Not sure what you found on it, but this is what I found:

I don't know what a firmware dump is, but that is available....

Hey, thanks Sis, I mean Cic

Cicero · 06-01-2008, 01:52 AM

This Is getting all complicated and conviluded, not sure if it is worth all the effort if I have to do it again after I "power off". If I figure it out I'll give you an update.

Oh shit. Now what am I gonna do with 300 lbs of potatoes?

HungLikeJesus · 06-01-2008, 04:50 PM

For your potato canon?

BigV · 06-01-2008, 05:55 PM

Confirmed.

I have downloaded the appropriate file and moved it to the SD card. The setup/installation routine in the camera is simple and reversible. I have experimented with only a couple of the enhanced features. I can say with authority that the Reversi game plays at a high level.

The other scripts, hard to say. I haven't yet figured out how to use the exposure bracketing script. It will *take* a series of pictures, but I haven't been able to find the combinations of settings that vary the exposure across the series. I did find a nice HDR assembler (free!). Now I need a .tif viewer. Downloading BravaViewer now.

Sadly, I had to retire the PC as it wasn't seen as pc. But xoB raised my hopes with his misleading thread title, the taunting vixen.

I have a Canon (one N)A 10 IS and I hope I can get it going. May have to wait until next week though.

BigV! show us the images!

BigV · 06-01-2008, 10:33 PM

Ok. Question. I am trying to setup the exposure bracketing. I have a choice to select the number of "csteps", and my current setting is 3. Also, the step size (1/3EV) is currently set to 3. I press the shutter release and the camera starts processing the script, produces 7 exposures, then says "script finished". I switch to display mode and review the shots and they're all identical. They all look exactly the same, and the max info display that shows exposure, fstop, ISO, white balance, etc., all the values are the same. Only the exposure number changes. And the moving part of what I shot changes, the live tv screen. I *know* I'm getting seven shots. But there's no change from one to the next. Nothing really to show, yet.

BigV · 06-01-2008, 10:35 PM

Right. Forgot the question. The big question is how do I make it work, of course. But I would also like to know what is a cstep?

footfootfoot · 06-01-2008, 11:15 PM

I wonder if you need to be in manual mode to bracket? auto or program mode may want to override bracketing in favor of "proper" exposure, or may bracket by changing f stop and shutter speeds proportionally, giving you the same net exposure.

I still ahven't downloaded the software yet...
