Pursuant to the recent Canon PowerShot G7 discussions in the "About This Site" section...

Since the G7 does not feature a RAW mode we're all shooting JPGs.  In this regard the camera features 11 "color modes", known cutely as "My Colors", accessible through the "Function" button.  Personally, I turn this feature off preferring to use the standard color renderings the G7 offers.  But being curious to see what these color modes featured I shot a series of G-M color chart images using each.  I though others might also be interested in seeing these images.

Sorry for the slight glare near the top of the charts, the result of using a single-source light.  Still, i think the images are reasonably illustrative.

As always, DPReview is your friend in such matters, provided that they've actually reviewed the camera.

I've just gone through the same process that Michael went through in looking for a pro quality copmpact and like him landed on the G7 as the only real affordable pocket rocket candidate.  I guess like just about every other serious shooter, the lack of Raw mode is just about the only flaw I can see with the G7.  And its a big flaw.

Just how bad are those blown highlights? Is 80 ISO noise free?  I've read the reviews, but remain sceptical because of Canon's dim decision to remove raw mode.  Its so frustrating.

Well I set aside reservations and I purchased a G7 today.  I note with interest the ability to chose low contrast (and sharpness) using the "custom color" menu and and reducing contrast.  I assume (but has anyone tested it?) that this will maximise dynamic range.  I'll give it a go tomorrow, but has anyone found the best settings for post processing in photoshop (not  ideal with jpegs but we don't have a choice)?

I think you'll enjoy the G7 very much.  I certainly am.

Perhaps a bit late but I think you'll enjoy DPreview's review, just posted yesterday.

I've been processing the files in Lightroom which provides a very raw-like feeling to the processing.  I've not really experimented with using My Color customization to produce a better file.  I suspect it's possible if you shoot similar subjects often.

Hi Ken

Yes, I'm thinking that what we need to do is preserve as much dynamic range in the jpeg as possible, and hopefully lowering the contrast in-camera will do that.  Its a well-designed and fun camera, and I'll be out and about today putting it to the test

In my G7, I am using -2 for contrast, and -2 for sharpness. So far, in shooting landscapes at dawn and dusk, I have not seen any blown highlights. Of course, it is necessary to check the histogram foten, just to ensure a "healthy" exposure.

I approach shooting the G7 the same way I do when scanning slides; I try to make sure I get a histogram that I can work with later on in Photoshop.
