Raw and raw conversion

Supplied software

The PowerShot G1 X is provided with the 'Canon EOS Solutions Disk' which includes:

  • Canon ZoomBrowser EX 6.5 - Easy to use image browsing and organization with a unique interface. Includes rudimentary image editing, printing and e-mail. This latest version of the software also provides some very basic video editing. - Windows only.
     
  • Canon PhotoStitch 3.1 - Panorama stitching utility.
     
  • Canon Digital Photo Professional 3.11.3.10 - Advanced image workflow and editing, specialized in RAW conversion with a range of adjustment and output options. *
  • Movie Uploader for YouTube - Tool for uploading videos to the Youtube website.
  • CameraWindow - Tool for transferring images to a computer

* Universal Binaries (Intel / PowerPC) for Mac OS X.

Digital Photo Professional is an image workflow and RAW conversion application that provides for the browsing and management of images in a folder structure as well as tagging, rotation etc. In addition it also provides an extensive range of RAW conversion features which include digital exposure compensation, white balance, tone curve, color, picture style, sharpness and lens correction parameters.

A number of different tools can be accessed from the tools menu. The Quick Check tool allows you to browse through a selection of images and assign check marks to them. The Trimming tool can be used to apply a crop to an image (the image itself is not modified, this is simply saved in the recipe).

The Stamp tool works in a similar way to the clone stamp or healing brush in Photoshop (although it is primary designed for the removal of light or dark blotches).The Rename tool can be used to change the filename of a selection of images based on a rule set. Finally you can convert multiple RAW files at a time using the batch conversion tool.

Digital Photo Professional has a comprehensive feature set. RAW conversion (in this image you can see the Edit window) certainly offers enough to satisfy even the most advanced user. In fact you can easily end up spending way too long trying the different sliders.... One of the main advantages of working with RAW files: DPP offers much more control over noise-reduction than the in-camera settings.
Tone curves can be adjusted for each color channel separately. The lens aberration window offers correction of light fall-off, chromatic aberration, distortion and color blur.

Raw conversion

As is normal in our reviews we like to compare the supplied raw conversion software, any optional manufacturer raw conversion software and some third party raw converter. For the purpose of this test we've picked Adobe Camera Raw alongside the Canon software. Here we compare these two converters to the camera's JPEG engine to see how each of them pulls detail out of the images.

  • JPEG - Large/Fine, Default settings
  • DPP - Digital Photo Professional
  • ACR - Adobe Camera raw 6.7 Beta

Sharpness and Detail

Like previous versions of the software and some other manufacturer-supplied raw converter Canon DPP emulates the camera's JPEG engine very closely. Color rendition, pixel-level sharpness and detail are, at default settings, as good as identical. However, when venturing away from DPP's default settings you can customize your settings for your specific requirements and, with the fine control over the type and level of sharpening being offered in DPP, get a little extra detail.

Adobe Camera Raw's color rendition is a little different, slightly less saturated and less 'punchy' in the red channel but at its default settings ACR is also squeezing some more detail out of the G1 X files than can be found in the out-of-camera JPEGs or the default DPP conversion.

Digital Photo Professional ->JPEG (Default settings)
ISO 100 studio scene 100% crop
Adobe ACR 6.7 Beta raw ->JPEG (Default settings)
ISO 100 studio scene 100% crop
JPEG out of camera, High quality setting (all settings default)
ISO 100 studio scene 100% crop

Resolution

When converting the raw file of our resolution shot the out-of-camera JPEG and DPP conversion are again nearly identical, producing clean files that are virtually free of artifacts but don't get the most of the captured data in terms of resolution. At default settings Adobe ACR does a better job, squeezing visibly more detail out of our resolution chart while not introducing any artifacts.

RAW vs JPEG

With its combination of a 14MP sensor and the good quality Canon zoom lens the G1 X captures a good amount of detail in a pocketable package. The camera's out-of-camera JPEGs already show a good level of detail and it is difficult to extract any additional detail through raw conversion. Processing the files in Adobe ACR and applying some custom sharpening (Amount 34, radius 0.6, detail 60) makes the image look a little crisper at a pixel-level but there is only a very minimal increase in detail. The sample below was shot at ISO 100, 1/250th sec, F5.6 at an equivalent focal length of 28mm.

Even if you're not a detail fetishist the ability to modify shooting parameters after an image has been taken, in raw conversion, can be extremely useful. Canon's White Balance tends to produce very warm results under low tungsten light. If that's not quite to your taste you can still snap away and take care of the problem in post-processing.

The picture below was taken under very low light with Auto White Balance which resulted in a strong yellowish cast. In Adobe ACR we modified the color temperature and tint parameters and slightly lifted the exposure to create a more pleasant end result. The sample below was shot at ISO 12800, 1/6th sec, F6.3 at an equivalent focal length of 28mm.

Raw files for download

Don't just take our word for it - take a look at the G1 X's raw files for yourself, and run them through your own software and preferred conversion settings. Here, we provide you with a selection of raw files of 'real world' scenes, and if you want to take a closer look at the G1 X's studio scene shots, you can download original raw files from our compared to (raw) page.

Still the same flimsy, delicate lens and leaf design, I assume. No thanks.
After both a G10 and a G16 succumbed to 'shutter error' (the G16 within a week), it's manual transmission for me from now on. Something I make work by twisting with my fingers.
Come to think of it, I lose count of the number of my devices which have died simply because the 'automated' systems failed. VCR's, tape-decks, Minidisk players, and now cameras.

I bought a G1X 2 weeks ago from a person that bought it for his wife for Christmas. She found it too much camera for her needs and so I bought it with about 10 shots total for $400. I usually shoot with a Nikon D300 and the Nikon higher priced lenses. For underwater and a light carry around I had a G10 for 5 years. After 2 weeks of shooting I must say that I'm amazed by the IQ of the photos this camera puts out. Low light shots up to ISO 1600 are allot better than my D300. It's not a perfect camera but then non of them are. Ordered a Canon 500D close up lens for it after seeing how well that worked on Marco Nero's photos with the G1X on www.pbase.com . This camera also shoots some very good underwater photos from examples I have seen on the internet so I picked up Canon's case on sale for my trips south. All told I think that although this camera is not for everyone most owners give it at least an 8/10. www.witnesstobeauty.com has another good review, great landscape photos

I've been wanting this camera since it was announced. I'm primarily a DSLR shooter, and FF at that. I also have owned a G6 and currently G10 and S110. So, I'm pretty familiar with where this camera fits in and what a step it is for Canon to take.
I just bought a used version at a very nice price so will be trying it out in the near future.
I would have rated the camera a little higher, based on my past experience with Canon and reports I've read from reviews and owners. Particularly, Optics and Performance would have got a couple ticks up in my estimation. I think a 79 or 80 would have been appropriate -- being practically in a category of its own: attached zoom, large sensor, compact camera.
It won't be a camera for everyone, true. But if you want better IQ than P&S and use it as a second camera to your DSLR for quick grab shots and take-anywhere convenience, you should be well served! :)

Image quality G1X, dpreview reports "excellent image quality across the ISO range without nasty surprises".
I would like to refer to the www.imaging-resourcing.com review of this camera. They reported a nasty Light Leakage phenomenon at higher ISO settings and short shutter times. This defect seems to be confirmed by Canon.
Would anybody comment on this ?

I've noticed that the g1x took this studio shot at f7.1 , while other "enthusiast" compacts (g15 or p7700...) at f4.5. Could somebody explain me why's that? It would be nice to know the shutter speed too. Thanks

It's to offer enough depth-of-field (it's a 3D target).

This has a sensor much bigger than the others, so needs to be stopped-down further in order to provide enough depth-of-field.

Please sorry my ignorance, but to achieve this it has to use a slower shutter speed too or, thanks to the higher light-catching capabilities of the bigger sensor the g1x uses comparable shutter speeds as, say, the g15 or p7700 , with a smaller aperture?

If Canon increases DR able to at least match T2i and updates its Panorama mode (similar to the Sony's would be great), this would be true compact I'm looking for. I'll buy it no doubts!

G1x Cannons almost camera
Almost an APS-C sensor, Almost a good EVF, Almost enough lens magnification, Almost small enough. A good first try for a company that just started designing cameras.
