Raw and Raw Conversion

Supplied software

The GXR-body comes with the Irodio Photo & Video Studio software package which offers a bit of everything - image browsing and editing (including RAW conversion) and video editing. Each of these main modes has a button on the application's main screen. While the white balance, exposure and sharpening options in the RAW conversion module are relatively basic there is a whole stack of image editing options available, including many filters and effects.

The video editing module adopts a story board approach which allows to compose movies from video clips and other types of media. You can create effects and transitions between clips, add captions and overlay audio. Considering it's a bundled software Iridio is quite comprehensive and offers enough functionalities to keep beginners and occasional RAW-users happy. However, if you're particularly fuzzy about your RAW conversion options you probably want to look out for alternatives with more options in that area.

Apart from Iridio you'll also find three small tools on the GXR software CD. There is the DL-10 application to copy pictures to the computer in a single operation plus USB- and WIA-drivers. The latter two are for use with older Ricoh models though and not required for the GXR.

This is Iridio's Browser view. Here you can organize and view images, rotate, resize and print them. Batch renaming using EXIF information is also available. In the editing window a comprehensive range of tools is available. This includes red-eye removal, basic editing such as cropping and resizing and an array of effects and filters.
The Warp filter lets you create distortion by moving nodal points on a grid pattern. A range of 'artistic' effects is available.
Video editing includes story board functions for composing videos from various media files, animations, effects, transitions, narrations and captions. The final product can be created in several file formats. The DNG RAW converter offers fairly basic white balance, exposure and sharpening options.

RAW conversion

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 converters. In the case of the Ricoh S10 24-72mm lens module we used the supplied Irodio Photo & Video Studio, Camera RAW 5.6 and Capture One 5.0.1

  • JPEG - Large/Fine, Default settings
  • IRO - Irodio Photo & Video Studio
  • ACR - Adobe Camera RAW 5.6
  • CAP - Capture One 5.0.1

Color reproduction

Place your mouse over the label below the image to see the color from a GretagMacbeth Color Checker chart produced using each RAW converter. Irodio produces a more muted color response that is not dissimilar to the out-of-camera JPEGs. The ACR and Capture One results are more vivid with a slight hue shift towards the reds in Capture One.

Sharpness and Detail

As we've seen in previous reviews different RAW converters produce fairly different results at their respective default settings. The color response varies and so does the sharpening. Capture One produces the most sharpened image here. In comparison the ACR and Irodio images are visibly softer. They are also slightly softer than the out-of camera JPEGs but obviously you can alter the output of all converters by modifying the default parameters. Graphics Converter (DCRaw) produces the most detail out of all the RAW converters here.

Graphics Converter 6.7 (DCRaw) ->JPEG (Default settings)

All RAW converters produce higher resolution than the out-of-camera JPEG file. However, the latter is the cleanest images as demosaicing artifacts and color moire are visible in all three RAW conversion (ACR is slightly better in this respect than the other two). Capture One also produces a fairly strong reddish color cast.

Real world advantages

While we used the converters' default settings for the studio shots above we played with the parameters for optimal results during the conversion of this real life shot. With some fine extra sharpening we could get some extra detail out of the image files. This is mostly visibly in the low-contrast foliage areas of the image. However, the difference will only be visible at fairly large magnification. Image noise, for example in the sky, also becomes more visible through the sharpening.
