This release introduces Booth Guest Control — a new touchless experience that lets guests control the booth from their own phone — along with major improvements to effects timing, Canon camera compatibility, and dozens of stability fixes.

Booth Guest Control

• Added Booth Guest Control, a new feature that lets guests start sessions, choose green screen backgrounds, select effects, pick templates, accept disclaimers, fill out surveys, and share photos via email or SMS — all from their phone by scanning a QR code displayed on the booth screen
• Simplified the Booth Guest Control QR code so it scans faster and appears less cluttered on the start screen
• Improved the responsiveness of Booth Guest Control by reducing the delay between guest actions and booth responses
• Resolved an issue where the Booth Guest Control QR code was incorrectly shown during effect or green screen background selection
• Fixed an issue where the QR code did not appear in single booth mode when green screen background selection or template selection was enabled
• Disabled Booth Guest Control when the license has expired, preventing unexpected behavior

Effects & Filters

• Changed the order of effects for photos and GIFs so guests now choose their effect after the photo is taken, giving them a real preview of how their image will look
• Effects for boomerang and video sessions continue to be selected before recording begins, as before
• Moved the effects panel to the top of the screen to work correctly with mirror booth orientations
• Added support for LUT (Look-Up Table) color filters, enabling Photoshop-style color grading to be applied to photos
• Fixed a crash that occurred when navigating through effect thumbnails when no effects were available

Camera Support

• Added separate camera settings for video and photo modes, allowing photographers who use flash to configure different white balance and other settings for live view, boomerang, and video recording
• Updated the Canon EOS SDK to fix a crash that occurred when Canon EOS Utility was running at the same time as dslrBooth; also adds support for the EOS R5 and EOS R6
• Added a clear in-app notice when Canon EOS Webcam Utility Beta is detected, which previously caused dslrBooth to crash

Session Flow

• Fixed an issue where the countdown trigger fired during the pre-countdown animation instead of at the start of the actual countdown
• Fixed a session flow issue when Virtual Attendant video, effects, and template selection were all enabled — the start screen animation was incorrectly replaying after template selection
• Fixed the after-capture audio clip so it plays correctly after each individual photo in a multi-photo session, not only after the final photo
• Fixed an issue where the survey appeared a second time after the guest added a signature, when both survey and signature were enabled

Sharing & Social

• Resolved an issue where Facebook albums were not loading in the sharing settings, preventing album selection
• Resolved a Facebook connectivity issue that caused an "access expired" error even after re-authenticating
• Updated Facebook permissions to use current, supported API scopes

Event Management

• Removed the limit that caused the saved events screen to show only the 7 most recent events; all events are now listed with a scrollbar when needed

Layout & Display

• Fixed the cancel button being hidden behind photo thumbnails when thumbnails were positioned on the left side; the cancel button now moves to the upper-right corner in that layout
• Fixed an issue where the green screen background selection was not displayed on the start screen when the live view preview was turned off

Stability

• Fixed a crash that occurred when dslrBooth was launched in full-screen mode
• Fixed a crash on startup when effects settings were carried over from version 6.34
• Fixed a crash that could occur when a video file (MP4) was mistakenly processed as an image during startup, which could prevent the app from opening
• Fixed a crash in the template editor that occurred when performing drag-and-drop operations
• Fixed a crash caused by a template loading error related to the undo framework
• Fixed a startup crash caused by a failure to locate the localization folder before other components initialized
• Fixed a startup crash affecting users who had not yet run version 6.36 but had an older version of the template manager DLL cached
