Thank you for using GR IV Monochrome digital camera.
RICOH IMAGING COMPANY, LTD. wishes to announce the release of Firmware Update Software Version 1.10 for GR IV Monochrome.

Applicable Models: RICOH GR IV Monochrome

Firmware in this document is the software that runs inside digital cameras.

Changes to V1.10

<Improved Contents>

• Added the [Solarized Effect] Image Control.
  This monochrome mode creates a fantastical and surreal effect through a unique rendering that includes inversion of the tones and contours of black and white images.
  You can shoot images while checking the effect in real time on the camera's rear LCD monitor immediately before shooting, without the need for darkroom processing and printing or image editing on a PC.
  You can also use the exposure compensation function to adjust the desired rendering and contrast between light and dark areas when shooting.
  
  When [Solarized Effect] Image Control is selected, press the Fn button to select from three types: [Type 1], [Type 2], and [Type 3].
  
  
  
  
  
  
  [Type 1] (Default)
  This mode boldly reverses the tones in the mid-brightness range while maintaining the brightness relationship between highlights and shadows.
  It produces an impressive and surreal effect characteristic of solarization.
  [Type 2]
  This mode creates two inverted areas in the highlights and shadows while maintaining the overall brightness relationship of the image.
  It retains a photographic appearance while making it easier to apply the distinctive solarization effect to areas such as the contours of the subject.
  [Type 3]
  This mode provides a more subtle effect without inverting the highlights. By reversing the tones in the shadow areas, dark areas appear to emerge, creating a unique glossiness that differs from reality and a subtle sense of unease.

• Added [AF Point] to [Mode Memory] under Menu > Custom Settings > [2] Operation Customization.
  When the check mark for [AF Point] is removed (set to Off), the AF point returns to the center position when the camera is turned off and then on again.
   *This applies when using Zone Select AF, Select AF, Pinpoint AF, Tracking AF, or Continuous AF.
  When the check mark is selected (set to On), the position of the AF point selected immediately before the camera was turned off will be retained, as before.
  

• Added [Restore USER Mode Settings] to [1] USER Mode under Menu > Custom Settings.
  

  When [Restore at Power Off] is selected, the settings registered in USER Mode will be restored when the camera is turned off and then on again.
  

  When [Do Not Restore at Power Off] is selected, the shooting settings in effect immediately before the camera is turned off will be retained when the camera is turned on again.
  

• Added [Connection When Power Off] to the Wireless Communication Settings under Menu > Setup > [6] Communication Settings.
  You can select [On] or [Off] for [Connection When Power Off].
  The screen below shows the Wireless Communication Settings selected under Menu > Setup > [6] Communication Settings.
  
  Pressing the Direct Key [Drive/Right] button on the screen above switches to the screen below, where [Connection while Power Off] can be set to [On] or [Off].

  
  When [Connection While Power Off] is set to [On] on the screen above:
  The camera remains in a standby state, continuously waiting to receive signals from the smart device app GR WORLD.
  Even when the camera is turned off, you can turn it on from the smart device app.
  Pressing the Direct Key [Drive/Right] button on the screen above displays the screen below.
  
  On this screen, select [Off] using the Direct Key and press the OK button to display the screen below.

  
  When [Connection While Power Off] is set to [Off] on the screen above:
  The camera will no longer accept any signals sent from the smart device app GR WORLD, helping to reduce battery consumption.
  To turn the camera on again, press the power button on the camera.

• Added the certification mark required for use in India.

• You can now change the end screen displayed when the camera is turned off using the smart device app GR WORLD.

• Improved stability for general performance.
