RAW shooting for Canon Point-n-Shoots
« on: February 18, 2008, 03:45:01 pm »

Came across this very interesting topic today. Basically through a firmware boot from the memory card, RAW capabilities are unlocked on many Canon Point and Shoots. Very tempted to pick up a $200 A720 and give it a try...

That's something I am going to bookmark for future reference. Thanks!

Very interesting, but also - it appears - rather time consuming.

Until my trusty s60 gives up the ghost, i'll probably pass - but as S3is shooting RAW is certainly appealing, this sounds like the answer for all the frustrated G7 owners

would certainly like to hear form someone who's done it before i jump in

A friend has this for his A sereis powershot - RAW write time is about a minute(!)

Yeah... The nice thing is that it appears to be non-destructive. Basically a piece of software that enables the RAW features. But I haven't tried it yet (no compatible camera) so I can't vouch for it...

What type of memory card is he using? That might be an explanation...

It's pretty easy really.

The software sits on the memory card, not in the camera (no overwriting or "flashing" of the camera software). If you "lock" the memory card then the camera boots up into RAW capture mode automatically when it is turned on. Simple.

If you don't like the software, or tire of using RAW, one just deletes it from the memory card and the camera reverts back to its original setup. I've been using it for five months now on the G7. Works like a charm!

these cameras probably just don't have enough buffer to handle RAW

Canon is missing an opportunity by not offering a premium compact with decent RAW capability advertised as a DSLR companion

HiltonP, can you comment on the raw write times for the G7? A poster above stated that it may take a minute...is this your experience as well? Also, can you comment on the workflow using these raw files from the G7? I believe that I've read that you can setup the G7 to write out the raw files as CRWs or CR2s...what difference would this make and how would raw converters like ACR interpret these files? And finally...can you comment on the quality of the G7 raw files as compared with the G9s raw files? Thanks for your time!

Personally, if I want to shoot raw, I'll take out a DSLR. P&S are for quick snaps where jpg is just fine.

Personally for me, it is just the opposite. I can't drag the big gear everywhere every time, so I want to have a camera in my pocket that shoots a picture I can work with, and jpg is not fine (for me).

But wouldn't the raw format be more advantageous for the P&S quick snap where perhaps the exposure isn't quite optimized and where a little more quality might be squeezed from the small sensor?

I use Sandisk Ultra II's and the write time is probably 3-4 seconds, although I have never timed it. The little blue write-to-card light flashes a couple of times and its over. I have yet to "wait" for the write process to finish, but then I do not shoot in bursts.

Yes, one can set the files to CRW or CR2. I convert them to DNG format and then use the DNGs in PS CS2 via ACR. One can use other de-coders such as RawTherapee as well. The CRWs or CR2s straight from the G7 cannot be read by ACR.  

Can't comment on the difference between G7 and G9 RAW files, but I do find the G7 RAWs useful for fine tuning photos which would otherwise have been poorer quality in JPG format. What is interesting is that most "normal" RAW files vary slightly in file size depending on the subject matter. The G7 RAWs are all exactly the same file size, to the byte, which points to them being a straight sensor dump.

Hope this helps.

Those would certainly be my thoughts Gordon! If you you at the side by side comparisons on the sight about image quality, there is definitely a difference.
