Version 3.9 of Phota provides the ability to detect and and properly interpret Color Space information that might be encoded in some photos.  A new BillBoards Gallery style has been added, and the Animate Colors feature has been much improved.  Some further details below:

• Color Management =>  Some digital cameras provide an option to encode photographs according to a particular Color Space.  A Color Space defines how the Red, Green and Blue (RGB) values recorded for each pixel of an image are stored, and how they should subsequently be interpreted when displayed or printed.  Color Space information is normally stored in the form of ICC Profiles that are embedded within the image files.  The most common Color Space is sRGB, which is typically the default Color Space used with display monitors.  However, images encoded with an alternate Color Space, such as AdobeRGB or ProPhoto, might appear drab or discolored if displayed on an sRGB monitor without appropriate conversion.

  When the Apply Color Management option is set, Phota will attempt to retrieve and interpret any Color Space information stored in Album image files.  If the Image Color Space differs from the Display Color Space, the image pixel values will be translated to properly express their intended colors.  This conversion only affects the display -- the images themselves are not altered.

• Billboards Gallery =>  The new Billboards 3D Gallery exhibits album photos as signs or posters that are positioned along both sides of a "road".   When Explore Gallery is activated the observer will automatically travel along the road and pause to admire each image in turn.  It's also possible to manually move around Gallery scenes via keyboard commands.  The photos displayed within a Gallery can be clicked to view them as full-screen images.
  

• Animate Colors =>  The Animate Colors feature has been greatly expanded and enhanced.  Now there are 5 Colorize Methods:  Garish (essentially the original method), Iridescent, Neonic, Opalescent and Contusive.  The Cycle Type parameter can be set to Switch Colors or Forward/Reverse.  The Animate Colors Options screen has been redesigned to allow interactive experimentation, so that the results of parameter adjustments can be reflected on the main Phota screen in real-time.  The current Color Step can be adjusted via a slider (the slider can also be moved with the Arrow keys or the mouse wheel).  Animate Colors Options can be conveniently accessed by right-clicking the Colors button.

  The Slide Show Configuration screen now includes a Color Seconds value to specify how long the colors of each image should be shifted.  While Animate Colors is activated, this value will override the Slide Show Display Seconds (or the Gallery View Seconds if Explore Gallery mode is active).
  

• Interface Scaling =>  The Album Appearance screen now includes an Interface Scale option.  When using a large, high-resolution monitor, the text and buttons on Phota screens and controls might appear rather small and difficult to read.  The size of text, buttons and other controls can be adjusted by switching the Interface Scale from the default Normal to Tiny, Large or Jumbo.  It's also easier now to save and apply default appearance values to be used when new Albums are initially created.
