CHDK hack for Canons (1 Viewer)

[HMD]

I've just installed it on my A650 IS to see what it does. I'm trying to get the bracketing function to work.

Anyone else tried it or can give me help?

I don't have a Canon, so can't help... just curious what a CHDK is or does??

It's for installing extra scripts on your camera to get additional functionality or something.

here's more info

i want to setup bracketing so i can try some High Dynamic Range stuff(it looks cool).

Wow, I'd be really interested in seeing the results if when you get it set up, have been ogling HDR stuff on Flickr for ages, some of it is a bit too much but when it's good it's breath-taking. this guy in my contacts on flickr is mad into it, he stuck up a tutorial http://stuckincustoms.com/2006/06/06/548/

might be some use to you as well.

thanks, thats the tutorial the got me interested in trying it. I'll post the results

I hate overdone HDR. Goes agin the grain of what it's supposed to do. Especially all that "haloed" shit. I have seen some good effects done that way though, gimmicky though they may be.

But, each to their own. You'll be more impressed with yourself when you do "perfect" shots.

Here, HMD. Did that hack let you save the files on your camera as RAW? If you didn't already have the ability and you do now, then use that as your format. You'll really benefit when using HDR. You can even get your bracketed images from the one file, if needs be.

The saving as RAW seems to be the main feature. I'll start using it over jpeg. Does it make that much difference in quality?

Ah jasus, yeah. It captures everything. And you can change the white balance and all that jazz after the fact. So it doesn't matter if you get a big orange picture when taking a picture indoors under tungsten light. You can fix it in Adobe Raw (Or a myriad of other packages).

Also, you've got more information captured in the file. Jpg is only 8bit per channel. RAW is usually 12 or more. And jpg is compressed.

You've a huge amount of control over the final output from a RAW file but there's less you can do with Jpg. You will have to convert the image into a format like jpg when you're finished if you want to do anything with it, but that's the beauty. Think of it as a digital negative, that will have to be processed. Jpg is a picture that has already been processed.

Best thing about RAW, as far as I'm concerned, is the fact that you can change the exposure when you get what would otherwise have been a shit image.

I hate overdone HDR.

it's becoming depressingly common though. as is fake vignetting.

It's a fad. It'll pass.

i've started to work in 16 bit recently on files, then saving back as 8 bit; a lot would be coming from an 8 bit scanner. the results look much better when you're trying to pull details out of shadow, etc.
