Raw and Raw Conversion

Supplied software

The EOS Rebel T3i / 600D is provided with the 'Canon EOS Solutions Disk' which includes:

  • Canon ZoomBrowser EX 6.7 - 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 2.10.0 - 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 3.10.0.0 - Advanced image workflow and editing, specialized in RAW conversion with a range of adjustment and output options.
     
  • Picture Style Editor 1.9.0 - Create custom Picture Styles.

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 usual 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 600D we used the supplied Digital Photo Professional and a release candidate of the forthcoming Adobe Camera RAW 6.4 plugin for Photoshop.

  • JPEG - Large/Fine, Default settings
  • DPP - Digital Photo Professional 3.10.0 (default settings)
  • ACR - Adobe Camera RAW 6.4 release candidate (default settings)
  • DXO - DxO Optics Pro 6.5.6 (default settings)

Sharpness and Detail

As we usually see with Canon cameras (and this is the fourth time that we have encountered this sensor), the JPEG engine does a pretty good job but there's more fine detail to be realized by switching to RAW and processing after the event. There's not a big difference between the JPEGs and the results of the supplied Digital Photography Professional software. However Adobe Camera Raw (which is compatible with Photoshop CS5, Photoshop Elements 9 and is identical to the processing in Lightroom 3.3), pulls out a fraction more detail in the really fine feathers.

JPEG (Default settings, manual WB)
ISO 100 studio scene 100% crops
Adobe Camera Raw 6.4 (rc) RAW ->JPEG (Default settings, manual WB)
ISO 100 studio scene 100% crops
Canon Digital Photo Professional, (all settings default)
ISO 100 studio scene 100% crop
DxO Optics Pro 6.5.6, (all settings default)
ISO 100 studio scene 100% crop

Resolution

The resolution charts tell a similar story to the test scene crops above - all stop showing further detail at similar resolutions but Adobe Camera Raw and Digital Photo Professional are applying more sophisticated sharpening to the detail they are pulling out. As a result the very fine detail around and above 2550 lph (about the limit of genuine detail) is much clearer in the crops taken from raw conversions.

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 JPEG image. Here we've only slightly adjusted the default sharpening of Adobe Camera Raw and it's been enough to pull much more lifelike detail out of the scene. We've also been able to remove the rather unpleasant chromatic aberrations that the Canon 18-135mm is rather prone to at short focal lengths.

RAW files for download

Here we provide RAW files, both from the review and the sample shots we take, to allow you to apply your own workflow techniques and see whether your experiences match ours.

Pretty good review, thanks.

I have had this camera for over 2 years. The video works very well for exposure, especially in difficult lighting areas. The problem is the focus is slow and hunts. It is best to use it in manual mode and with fairly fast lenses. This was an upgrade to EOS 350, but I only use 2 of the lenses I used before with the 600D - Canon EF 50mm 1.8 and Sigma 70-300 mm. Photos are good and the lens profile works well with the Canon lenses I have. Profile does not work with non-Canon lense like my sigma 17-70 2.8-4 and the 70-300mm. I have also bought a Canon 10-18mm wide angle lens to add to the 18-55 is and 55-250 is lens, plus the lenses mentioned earlier.
I had to buy Nissin flashes as the Sigma 500 flash is not compatible, even after being sent to Sigma for a fix.
The worst issue is the slow focus in live view. Fast lenses are better, but it is best to go manual or use the view finder. I was think of getting the 700D, but not sure if it is worth it, even with the upgrades.

Great camera for shooting still photos. The quality is superb and low-lighting is a breeze (as soon as you get used to working the correct settings).
The main reason I chose the T3i was for the 1080p video is offers. The video quality is great, but there are a few things to be aware of.
You'll want to get a memory card rated at a 10 for speed, and make sure it's a good-quality brand. If you scrimp on the card you'll forever be hitting yourself when the video recording repeatedly stops for no apparent reason. I have been through three cards that don't cut it (three different brands). Make sure you shell out the money for a quality card or you won't be able to record the data fast enough for 1080p (particularly in bright lighting or when you have a light source in the background--like a TV or lamp).
Enjoy!

This is my first DSLR as well and I think it functions very well. I use the kit lens and additionally I bought a telephoto zoom lens 55 to 250mm (f4 to f5.6) and a prime 50mm (f1.8). The camera gives me reasonably sharp shots. It does not have as many focus points as a competitive Nikon D3200. I post process with Aperture and then the pictures look even better!

This is my first DSLR, coming from two previous Canon PowerShot cameras and a Minolta 35mm SLR. For my purposes (not professional) this camera has been outstanding. I mainly wanted a camera that allowed me to take better family and vacation photos and one that would allow me to learn about shooting manually. I also feel confident that lens purchases I make for this camera will be supported on better Canon cameras should I see the need for it in the future.

Even for an amateur camera very well. Of course, for a good job requires additional configuration. Plus, the lens plays an important role. That the work of the unit, I want to note the high processing shots. Good sharpness and color rendition. In general, a good camera. And not expensive!

Canon t3i 600D

This new piece of kit is very similar but quite a few dollars cheaper. The specs are similarly very close, with one exceptional difference: the new baby is 240 grams lighter in weight, made from stainless steel and polycarbonate resin with glass fibre. Which says a lot: pros like cameras with a dab of weight while the amateur fraternity goes kinky for models that don’t lower the shoulders.
