Canon Digital Photo Professional 2.1.1

Digital Photo Professional is an image workflow and RAW conversion application. It 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.

Key changes in version 2.0

  • Additional camera support new EOS models (plus EOS D30)
  • Support for Picture Styles
  • Quick check window from main window with multiple images selected
  • Three types of checkmarks
  • Creation of folders from browser
  • Sharpness function enhanced: per image and real time preview, saved in recipe
  • Enhanced image correction functions:
    • Two new tools for light marks in dark areas and dark marks in light have been introduced using the Canon FARE dust and scratch removal algorithms from Canon scanners
  • Single key transfer of a single image to Photoshop
  • Additional color space support:
    • Apple RGB, ColorMatch RGB, sRGB, Adobe RGB and Wide Gamut RGB
  • CMYK simulation now adds a choice of perceptual or colorimetric intents

Key changes in version 2.1.1

  • Support for EOS 30D
  • "Tone curve assist function" - automatic RGB tone curve based on image analysis
  • Contact sheet print and detail settings print functions added
  • Addition of chrominance noise reduction and luminance noise reduction options

Main Window (Thumbnail index view)

The browsing / thumbnail view has three different size options as well as an option of a thumbnail with information view as seen below. Note that adjustments such as RAW brightness (digital exposure compensation) and white balance can be made to single or multiple files and are stored in the RAW file 'adjustment recipe'.

Small thumbnail Thumbnail with information

Main Window Tools

In addition to RAW adjustments you can also access five different tools from the thumbnail index. 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 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.

Edit image window

Select one or more images and click on the 'Edit image window' (or simply double click on a single image) to switch to the edit window where you can carry out various RAW adjustments such as digital exposure compensation, white balance, tone curve and color. One big change in DPP 2.0 is the that (finally) sharpness has been provided as an image parameter which is also stored in the conversion recipe. The other biggest change is the addition of Picture Style, each Picture Style is a combination of tone curve and color map designed to deliver images with a certain 'look'. Picture Style defaults to Neutral for the EOS-1Ds Mark II (and previous EOS-1D series models) and Standard for the EOS 300D, EOS 350D and EOS 20D.

Edit image window adjustments

On the right side of the edit window are two pages of adjustments accessed by two tabs labeled 'RAW image adjustment' and 'RGB image adjustment'. The easiest way to think about these two sets of adjustments is this; RAW adjustments are applied before RGB adjustments, that the RGB adjustments are similar to an 'adjustment layer' applied to the image after it had been through the RAW processing stage. This also produces a slightly confusing double layer of adjustments such as levels, hue, saturation and more importantly sharpness. You can set RAW sharpness (0 to 10) and RGB sharpness (0 to 500), we found no fundamental advantage between using just RAW sharpening or just RGB sharpening (with RAW sharpness set to 0).

Note that in addition to these settings you can also choose three RAW conversion 'operating modes' (quality, standard and speed) which equate to the quality of conversion used versus the time to convert. Also DPP 2.1 adds selection for luminance and chrominance noise.

Preferences

The preferences dialog box allows you to configure various aspects of DPP including features such as the operating mode (quality / speed), noise reduction, working color space and printing / CMYK simulation color profiles. DPP doesn't pick the correct monitor profile automatically so it's a good idea to set this when you first start using it.

This latest version of DPP provides for control of luminance and chrominance noise reduction as well as operating mode (the later option has been available for some time).

Operating mode

  • Quality - False color (moire) and noise reduction applied to display and saving
  • Standard - False color and noise reduction applied only when saving
  • Speed priority - No false color or noise reduction is applied even when saving

Noise reduction

  • Reduce luminance noise - Grainy noise that appears on images taken at high ISO speeds, or on images for which brightness has been edited even when taken at low ISO speeds. In some cases this noise appears as jaggies on diagonal lines. *
     
  • Reduce chrominance noise - Colored smears that appear on images taken at high ISO speeds, or on shadowed image portions, even when taken at low ISO speeds. *

The 30D had a 50 mm lens and the 5D had an 85mm lens and that could account for the difference in reading the globe etc.
