Canon EOS 7D Review
Raw and Raw Conversion
The EOS 7D is provided with the 'Canon EOS Solutions Disk v21.0' which includes:
- Canon ZoomBrowser EX 6.4 - 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 EOS Utility 2.7 - Automatic or Manual transfer of images via WIA, also allows for the adjustment of camera settings and remote 'tethered' shooting. *
- Canon PhotoStitch 3.1 - Panorama stitching utility.
- Canon Digital Photo Professional 3.7 - Advanced image workflow and editing, specialized in RAW conversion with a range of adjustment and output options. *
- Picture Style Editor 1.6 - Create custom Picture Styles. *
* 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.
As is normal in our digital SLR reviews we like to compare the supplied RAW conversion software, any optional manufacturer RAW conversion software and some third party RAW converter. In the case of the EOS 7D we used the supplied Digital Photo Professional, Adobe Camera RAW 5.6 Beta and a Release Candidate 2 version of the new Capture One Pro 5.0.
- JPEG - Large/Fine, Default settings
- DPP - Digital Photo Professional 3.7
- Cap One - Capture One Pro 5.0 RC2
- ACR - Adobe Camera RAW 5.6 beta
Please note that our version of Adobe ACR (5.6 Beta) had according to Adobe not been fully optimized for the EOS 7D yet. Once a full version becomes available we will reprocess these samples and replace them where necessary. Thanks to Eric at Adobe for making this 'pre-beta' version of ACR available in time for this review.
Place your mouse over the label below the image to see the color from a GretagMacbeth ColorChecker chart produced using each RAW converter. As we would expect there is hardly any difference between JPEG from the camera and Digital Photo Professional. Adobe Camera RAW and Capture One's default settings take slightly different approaches to color response and tone curve.

Sharpness and Detail
The sharpest image was produced by Capture One although the end result looks almost slightly over processed. DPP and Adobe ACR deliver a better balance between image detail and sharpening. All RAW samples show a tad more detail in the feathers than the out-of-camera JPEG.
|Digital Photo Professional -> TIFF (Default settings, manual WB)
ISO 100 studio scene 100% crops
|Capture One Pro ->JPEG (Default settings, manual WB)
ISO 100 studio scene 100% crops
|Adobe ACR 5.6 (Beta) RAW ->JPEG (Default settings, manual WB)
ISO 100 studio scene 100% crops
|JPEG out of camera, High quality setting (all settings default)
ISO 100 studio scene 100% crop
These crops demonstrate that more detail is available from the RAW converters than can be obtained from JPEG. That said, a lot of this detail could be described as 'false' (produced beyond Nyquist), although frankly the majority of the time this is useful as it improves the appearance of 'texture'. The ACR output looks a little softer than DPP. Again, Capture One is close to being over sharpened.

Real word advantages
What we've seen above on the test charts of course also works on real life shots. Some careful sharpening in the RAW conversion will generate visibly more detail than can be seen in the JPG image. The difference is not enormous though and you'll have to zoom in quite a bit in order to spot it.
