Base Characteristics for CH

Capture One CH has a special Film Reproduction Mode in the Base Characteristics tool that handles the conversion of positive and negative black & white and color film as well as other transmissive materials.

In addition, Capture One CH also ships with a number of ICC input profiles specifically for Phase One digital backs and various light sources, particularly flash and tungsten.

The Film Reproduction Mode drop-down menu is used for the conversion of positive and negative black & white and color film as well as other transmissive materials. It applies automatic conversion adjustments and employs the appropriate film curve characteristics based on the selected ICC color profile prior to the user’s manual adjustments.

The Film Reproduction mode is located in the Base Characteristics tool in the Pre-Flight Tab, the Tone and Color Tab and QC Tab, depending on the chosen CH workspace. Like all other tools, it is available in all Tabs, by using the Add Tool option.

Capture One Cultural Heritage ships with a number of ICC input profiles specifically for Phase One digital backs and various light sources, particularly flash and tungsten. All recent digital backs have a profile specifically optimized for Flat Art Reproduction using flash. These are also available from the Base Characteristics tool.

Most of the Phase One digital backs and cameras have additional ICC profiles that are optimized to be used in combination with the LED lights supplied with the DT RGC180, DT RG3040, DT Atom, and DT BC100 reprographic solutions. These profiles have been designed to match the specifications of common reproduction standards such as those specified by Metamorfoze and FADGI.

 

Invert Negative or Positive Film

1. From the Base Characteristics Tool, click on the Mode drop-down menu and change the default operating mode from Photography to Film Negative or Film Positive, depending on the film type captured.

2. Change the Channel Mode for Auto Levels in the preferences under the Exposure tab to use the individual Red, Green and Blue Channels Mode instead of the default RGB mode. See Change the Channel Mode section for full instructions.

3. Apply White Balance adjustment, typically using the neutral frame.


4. Set a crop using either the Crop Tool or the Auto Crop Tool.

5. Apply Auto Levels. Note that when using the Auto Crop Tool it is possible to have Levels adjusted automatically after the auto crop by choosing Auto Levels on Interior Crop in the Optimization drop-down menu.


Tip. If the capture includes a large unshielded area of the light-box, crop individual frames before applying levels adjustments.

Specialized ICC Input Profiles

The ICC profile is selected via the Base Characteristics tool, which is located under the Pre-Flight Tool Tab, Tone and Color Tab or QC Tab depending on the chosen Workspace. Capture One automatically identifies the Camera make and model and applies an ICC Flash profile by default.

1. Locate the Base Characteristics tool.

2. From the ICC Profile drop-down menu, select the appropriate profile for the Phase One back from the list. Note that the specialized profiles for LED light etc. are found in a sub-menu under the Cultural Heritage menu item.

 


Tip. The chosen ICC Profile can be set as the default (along with the Mode and Tone Curve). Click on the Action menu [...] icon in the top-right corner, and select Save as Defaults for Phase One IQXXX.
