v5.21.0821.1 August 21, 2018

This release delivers a wide range of improvements across the photo booth experience, including new session flexibility, enhanced camera compatibility, a redesigned signature screen, better touch screen support, and dozens of stability and quality-of-life fixes.

Session & Booth Modes

  • Added the ability to choose between Photo, GIF, and Boomerang sessions from the start screen, giving guests more flexibility at events
  • Improved the start screen to correctly show session-type options when a virtual attendant video is configured
  • Resolved an issue where choosing Boomerang-only mode with multiple favorite templates would incorrectly show the template selection screen
  • Fixed an issue where the start screen animation would not appear when only one booth mode option was selected
  • Templates on the start screen are now centered when guests are allowed to choose their own

Event Management

  • Added the ability to save and reload settings per event, including templates, green screen backgrounds, and camera settings — making it easy to switch between recurring events or return to a previous setup
  • Settings and templates are now automatically migrated when the data directory is changed in settings
  • Improved protection against settings file corruption — the app now writes settings safely and keeps a backup to recover from crashes automatically

Digital Props

  • Added digital props support, allowing guests to add fun overlays to their photos before final processing
  • Resolved a memory issue that caused the digital props screen to hang or crash when using high-resolution DSLR photos

  • Updated Canon EDSDK to version 3.8 to support additional Canon camera models including the EOS M50, EOS Rebel T7, EOS 2000D, and EOS 4000D
  • Updated Canon EDSDK to version 3.6 to add support for the EOS 800D, EOS 77D, EOS M5, EOS M6, and related models
  • Added support for Nikon D5600, D7500, D810a, D850, V1, V2, V3, J3, and J4
  • Fixed an issue where Nikon D7500 and D7100 cameras were incorrectly identified as shooting in RAW-only mode, preventing sessions from starting
  • Fixed an issue where the wrong shutter speed was restored after live view ended on Canon cameras with Bulb mode set

  • Fixed an issue where only one frame was included in the generated GIF on some Surface Pro devices
  • Resolved a Boomerang processing failure caused by frame delays above 500ms

Photo Quality & Processing

  • Fixed low-resolution output when photos were placed in stretched placeholders in a template
  • Fixed an issue where retaking a photo on a single-photo template could result in an empty print file being processed

  • Fixed an issue where GIF-only sessions with a single-photo template would fail to process
  • Sped up photo capture by triggering the shutter sooner and updating the progress indicator more frequently
  • Sped up processing for single-photo sessions by skipping an unnecessary live view cycle
  • Pre-starts live view after each capture to reduce the delay before the next countdown

Sharing & Email

  • Fixed sharing success messages incorrectly saying "photo shared" when a video was shared

  • Fixed uploads to Amazon S3 failing for events with non-Latin characters in the album name
  • Changed the outbound email sender domain to improve deliverability with German email providers such as gmx.de and web.de

SMS & Twilio
