This release is all about stability: a crash that could interrupt event setup is fixed for good.

Stability

• Fixed a crash that could happen when picking a device's screen resolution in the Screen Editor, so setting up a new event's display now goes smoothly from the very first step.

This maintenance release fixes a camera issue introduced in a recent update, restores AI portrait preset thumbnails, and makes printing more reliable during live events.

Camera & Capture

• Resolved an issue where the camera could no longer be triggered after pressing Cancel or Retake on the last photo of a session, affecting both DSLR cameras and webcams.

AI Portraits

• Built-in AI portrait presets now keep their thumbnail previews after an app update, so guests can always see what each style looks like before choosing it.

Printing

• Fixed an issue where prints and previews could suddenly come out completely white partway through an event when event settings refreshed in the background.
• Added extra safeguards and diagnostics so the print layout automatically recovers if it is ever lost during an event.

This is a major stability release: dozens of rare crashes have been fixed across startup, templates, settings, printing, and camera handling, alongside meaningful screen editor and video improvements, including choosing the device your welcome/sharing screens are designed for and fixing missing video overlays.

Screen Editor & Templates

• Added the ability to choose which device (phone, tablet, or desktop) your welcome and sharing screens are designed for, so your layout always matches the device guests will actually use.
• The screen editor no longer resets your design's aspect ratio back to 16:9 unexpectedly after changes made in the online dashboard.
• Each monitor's display scale is now respected on multi-monitor setups with mixed scaling, instead of the wrong scale being applied to secondary screens.
• Resolved templates occasionally failing to load with a generic "Error loading template" message.
• Capped welcome/sharing screen image layers to prevent out-of-memory crashes on iPads with heavily layered designs.
• Matched photo layout sort order to the online dashboard so templates appear in a consistent order everywhere.
• A pasted image on the Share screen no longer gets stuck and unable to be deleted or modified.
• Built-in Virtual Attendant assets from older installs now load reliably.

Video (360, Slow-mo, Boomerang)

• Default video overlays (Hearts, Sparkle, Bokeh, Stars) now appear correctly on the final 360/Slow-mo video.
• Added the ability to mirror/flip captured photos and videos to match your preferred booth preset orientation.
• The 360/Slow-mo countdown now uses its own timer instead of being controlled by the Video countdown setting.
• Boomerang videos in 360/Slow-mo mode now apply their timeline correctly.
• Replaced a crash with a clear warning when an unsupported video format is used in 360/Slow-mo preview.
• Added support for the Sony A7R IVA camera (photo capture).

Printing & Sharing

• The Print button now works correctly on the sharing screen when the session is started by reading a QR Code.
• Generalized 2-per-page printing to work with any template size, not just a fixed set.
• Reordered the GIF size dropdown for easier selection.
• Print setup text (pricing message, copies label, button text) now syncs and translates correctly in all languages.
• Corrected the Portuguese print screen showing SMS text instead of the copy count.
• Survey answer text in photo layouts now uses the correct Google Font.

AI Portraits

• AI Portrait sessions with Upload Originals turned off no longer upload an extra, unwanted image to fotoShare.

Stickers

• Sticker style selection (Default vs Custom) is now respected, matching the iOS app.

Event Management

• Duplicating a Windows event from the dashboard now copies the "Start App in Full Screen" and "Force Windows virtual keyboard to show" settings.
• Resolved a crash that could occur when changing settings on events created with an older app version.
• Booth API's /api/cancel command now works correctly instead of returning "Invalid command specified".

Stability

A major stability pass across the app: dozens of rare crashes have been addressed so the app now recovers gracefully or shows a clear message instead of closing unexpectedly. Highlights:

• Startup no longer crashes when security software blocks a required file, an app icon is missing, or settings are misconfigured.
• The Template Editor and Screen Editor handle deleting templates, adding layouts, and loading a template while data isn't fully ready without crashing.
• Clipboard copy (Ctrl+C, copy buttons) recovers cleanly instead of crashing when another app is briefly holding the clipboard.
• A disconnected camera, a dropped GoPro connection, or an event referencing a camera that's no longer connected no longer brings the app down.
• Event and asset management (renaming, deleting large numbers of events, viewing recent shares) is now resilient to these edge cases instead of crashing.

This update keeps your custom AI portrait presets looking exactly as you designed them, so your branded booth experience stays consistent from setup through every event.

AI Portraits

• Fixed an issue where custom AI portrait preset thumbnails could disappear from your dashboard after an event was opened and synced on Windows, so your saved presets now stay intact.

This release sharpens reliability across cloud syncing, printing, and camera capture while adding new GIF formats and polishing the event and settings experience for smoother events.

AI Portraits

• Resolved an issue where duplicating an event could cause its AI portrait reference images to be shared with the original, so editing or deleting one event no longer affects the other.

GIFs & Animations

• Added new 3:2 and 2:3 aspect ratio options for GIF animations.
• Square GIF animations now crop from the center for properly balanced framing.

Cloud Syncing

• Custom sticker images now sync reliably across all your devices.

• Improved Canon capture reliability by resolving false "memory card full" errors.

Capture Experience

• The cancel button now appears during photo review even when a custom "Say Cheese" image is loaded, so guests can retake their photos.

Stability

• Resolved an issue that could cause the app to become unresponsive on the sharing screen after a session if there are printing issues.

Interface Polish

• Refined the alignment of the on/off switches in the screen editor settings.

This update polishes the on-screen sharing experience, giving guests a cleaner way to revisit everything they captured and making sure your gallery settings are respected.

Sharing & Gallery

• Added a single, redesigned session gallery button on the sharing screen — guests tap one elegant photo-frame stack to open a full-screen preview of everything from their session, including photos, prints, GIFs, boomerangs, slow-motion clips, and videos.
• Improved the session preview so every captured item appears at full size in a clean, evenly spaced grid for crisper, easier viewing.
• Gave you control over the gallery button's frame styling, with adjustable border color.
• Resolved an issue where the "Show original photos" setting was ignored on the sharing screen, so your preference is now always honored.

This release brings personalized AI Portraits, a cleaner unified session gallery on the sharing screen, a refreshed guest-screen look, and a range of fixes that keep events loading, launching, and running smoothly — even offline.

AI Portraits

• Added support for Custom AI Prompts, in addition to our AI Portrait and Art Style presets, so you can write your own prompt to generate exactly the look you want.

• Resolved a crash that could occur when last events photos were deleted from the computer.

Camera Support

• Fixed an issue where a "video too short" error appeared when attempting to take a photo with a Canon camera set to RAW+JPG mode.

This release brings broader Canon camera reliability, smoother touch interaction in the editors, refined Welcome screen controls, and a long list of fixes for sharing, printing, AI portraits, and event migration.

Camera Support

• Added a friendly on-screen warning when a Canon shutter is blocked because the lens is retracted or no lens is attached, instead of failing silently.
• Added a clear message when a Canon camera overheats and can no longer record video.
• Fixed a rare crash when switching cameras while live view was stopping.
• Improved Canon EOS R50 reliability in 360/Slow-mo sessions so recording stops cleanly instead of leaving the camera stuck in record mode.
• Resolved a countdown freeze on Canon EOS M50 Mark II when starting video sessions by waiting for the camera to finish initializing before applying movie settings or when cancelling a session.

Photo & Video Sessions

• Fixed a freeze at the final countdown when using AI Background Removal with a custom background image with older Canon cameras.
• Resolved a Beauty Filter issue that could cause DSLR video sessions to silently fail before reaching the sharing screen.

Photo Layout Editor

• Resize handles are now larger and styled to match LumaBooth on iOS and the Dashboard, making them easier to grab on touch screens.
• Selection borders and corner handles now use the primary theme color, and the rotate handle has been restyled to match iOS.
• Resize handles now scale with the canvas zoom level so they stay usable at any zoom.
• Sliders throughout settings and the editor now respond immediately to touch drag instead of requiring a press-and-hold.
• Decimal values such as 4.2 cm are now accepted in Width and Height fields when using centimeters.

Print Setup

• Removed outdated helper text for limits on number of copies.

AI Portraits

• AI Portrait improvements for preparation for Custom prompts.
• The AI Portrait progress bar now paces itself based on each preset's expected processing time.

Sharing

• Pending and sent counts on the Sharing Status detail screen now reflect the true number of items instead of being inflated by retry attempts.

Background Removal

• Fixed the trash can button so it now actually deletes background images.

Diagnostics

• The exact build version is now recorded in the logs, the About screen, and support emails so we can pinpoint which build a customer is running.

Bug fixes

• Fixed an issue introduced in v8.1.24 where, if you had an end-of-session video set in Virtual Attendant, the start screen video would stop playing after the first session and not resume between sessions.

This update focuses on stability, smoother event setup, and more flexible print and event management — including support for any characters in event names and per-event print preferences synced from your dashboard.

Event Management

• Resolved an issue where deleting all events and creating a new one could leave the start screen without any start buttons.
• Event names can now contain any character, including colons, apostrophes, and slashes — downloads, renames, exports, and deletions all handle these names reliably.
• Fixed a problem where downloading a cloud event whose name contained illegal filename characters would fail and leave the event partially synced.
• Resolved an issue where making template changes in the app could remove the template from the dashboard and iOS.

Printing

• Print automatically, Show print button, and Print to both printers are now event-level settings and can be synched to LumaBooth for Windows. Coming to the Dashboard soon.
• Streamlined Print Setup by removing rarely-used options (print sharpening, print window max, print auto-rotate) and applying sensible defaults automatically.
• Clearer wording and localization for Per Event, Per Session, and the Show print button explanation.
• Fixed the +/− signs not appearing on numeric controls in Print Setup.

Screen Editor (over remote connections)

• Resolved an issue where clicking the Done or Retake button in the Sharing Screen editor would shift the button off-screen as the right panel expanded.
• Fixed a phantom drag that could move template elements unexpectedly when toggling tabs.

These issues only occurred when using the Screen Editor over a remote desktop connection.

Virtual Attendant

• Virtual attendant videos now start promptly throughout long events, instead of taking progressively longer to begin playing as the software runs.
• Fixed a problem where virtual attendant video files with spaces in their filenames would fail to download.

Stability

• Hardened background tasks in Settings so unexpected errors no longer cause the app to close silently.

This release resolves two issues affecting cloud sync reliability — one that could silently drop your template configuration from the dashboard after making in-app changes, and one that prevented virtual attendant videos with spaces in their filenames from uploading and downloading correctly.

Cloud Sync & File Sharing

• Resolved an issue where editing a template inside the app would cause it to disappear from the dslrBooth dashboard and the iOS app, even though it continued to work locally
• Resolved an issue where virtual attendant video files with spaces in their filename would fail to upload or download from cloud storage

This release brings a number of reliability and compatibility improvements across cloud sync, virtual attendant, and general app stability.

Stability

• Improved how the app handles background operations in the Settings window and Screen Editor
• Better handling of virtual attendant asset filenames on lower-powered computers

Cloud Sync

• Improved cloud sync reliability for long sessions
• The app now notifies you if the Windows system clock is out of sync with internet time, which can affect sync

• Improved touch scrolling for digital props, video timeline, and animated video overlay lists when running in touch fallback mode
• Resolved an issue where action buttons in the asset preview could interfere with touch panning in fallback mode

Customization

• Resolved an issue where Done and Retake button graphics were not displayed for events created from the dashboard; the correct graphics now load automatically without requiring a manual reset
• Fixed an issue where the default sharing screen template did not apply the correct style to both the Done and Sharing buttons

This release polishes the first-time setup experience, makes launching an event feel snappier, and fixes several issues around template previews and the guest-facing template selection screen.

Event Management

• New users are now taken straight to event creation on first launch, instead of landing on an empty Event Management screen.
• Added a loading indicator to the Launch Event button so it's clear when an event is starting, and prevented accidental double-taps from launching twice.

Template Selection

• Removed silhouettes from Select a template guest screen

Guest Experience

• The guest-facing template selection screen no longer pre-selects a template, so guests make a deliberate choice.
• Resolved paging issues on the template selection screen, including an edge case with minimal scrolling and inaccurate page indicator dots caused by variable thumbnail widths.

This update brings a more polished guest experience with live template previews, refined settings screens, and important stability fixes for Windows 11 setups.

Template Selection

• Guest-facing template previews now show simple gray boxes for where the photos go so guests see exactly what their final photo will look like.

Background Removal & Settings

• Corrected the alignment of the Background Removal settings header so it matches the rest of the settings screens.

This release brings a cleaner, more professional look to the guest experience, improves template management, and updates the app's branding to match the new website identity.

Template & Layout Management

• Improved the "Recent" layouts list so it now shows templates used across all past events, not just the current one

Branding

• Updated the application icon to match the new website favicon for consistent brand appearance across the taskbar, Start Menu, and window title bar

This is a maintenance release with internal improvements to ensure LumaBooth for Windows continues to install and run smoothly.

Improvements

• Resolved an issue that could prevent LumaBooth for Windows from launching on certain Windows configurations

This release focuses on stability improvements, addressing several crashes that affected users during sessions and at app startup.

Stability

• Improved reliability for brand-new accounts where the app could fail to sync event preferences correctly, leaving events in a broken state that prevented launching a session
• Fixed a crash that could occur when a camera was disconnected while the app was in the process of closing
• Resolved a startup crash affecting some users where a component version mismatch caused the template editor to fail immediately on launch

This release brings meaningful improvements to multi-monitor setups, faster gallery navigation, and several stability fixes that address startup crashes and session failures due to new Windows Security restrictions.

Multi-Monitor Support

• Improved multi-monitor support so that effects selection and other popups always appear on the correct screen when multiple monitors are connected

Stability & Startup

• Resolved a startup crash affecting some Windows systems where certain app components could be incorrectly blocked by Windows security features, preventing the app from launching
• Improved early crash detection so that any startup errors are now captured and reported before they can silently disappear

Events & Sessions

• Fixed an issue where corrupt or empty overlay files (0×0 pixel, unnamed PNGs) could cause sessions to fail — these invalid assets are now safely skipped
• Fixed an issue where duplicating an event could generate overlay files with missing names or missing file extensions, which could cause session failures

Photo Preview

• Fixed an issue where photo preview thumbnails appeared as squares and cropped subjects out of frame — previews now display correctly centered and proportioned

This release brings major touch-screen reliability improvements, smarter AI portrait handling, and several bug fixes for screen templates and sharing.

Touch Screen

• Improved touch scrolling and panning across all settings screens, the template editor, survey, and new template panels — especially on devices with non-standard touch drivers such as ARM-based tablets.
• Enlarged tap targets for tabs, menus, and navigation buttons so they respond to the full button area, not just the text label.
• Fixed an issue where sliders, toggles, and drag-and-drop controls could stop responding to touch input.

AI Portraits

• Added warnings when too many faces are detected, faces are too small, or no face is found — helping guests get better AI portrait results and reducing wasted credits.
• Webcam quality is now automatically increased before an AI portrait session to ensure the best possible results.
• Resolved a failure during AI background removal that could prevent final processing from completing.
• AI background removal now falls back to CPU processing if the GPU encounters an error at runtime, improving reliability on a wider range of hardware.

Screen Templates

• Reduced false screen-resolution warnings by using logical resolution for template comparisons and improving how screen size is communicated to LumaBooth Dashboard.
• Resetting a screen template no longer deletes custom elements or removes customized images — and you can now reset directly from the resolution-mismatch warning.
• Reorganized Welcome Screen settings so that live-view-related options are grouped together and hidden when live view is turned off.

Sharing & Gallery

• Improved gallery thumbnail selection responsiveness on the sharing screen with instant transitions and background loading.
• Fixed a lock button that incorrectly appeared on the sharing screen settings preview.

General

• Fixed the app failing to start when installed on a drive other than C:.

Photo Capture

• Fixed countdown not starting when thumbnails are positioned on the left or right — Photo sessions now begin correctly regardless of thumbnail placement. Previously, setting thumbnails to the left or right side caused the capture screen layout to shake and prevented the countdown from starting.

Green Screen

• Fixed green screen backgrounds and overlays failing to load after switching events — Background and overlay asset paths are now resolved at the correct time, so switching events from the navbar no longer causes green screen assets to point to the wrong event folder.

Stability

• Fixed crash when launching an event immediately after upgrading from an older version — Users upgrading from earlier dslrBooth versions that didn't persist an event selection could encounter a crash when clicking the Launch Event button. The app now guards against this condition gracefully.

This release improves reliability for start screen videos and fixes a crash affecting users on Snapdragon-powered devices.

Start Screen & Virtual Attendant

• Resolved an issue where start screen videos would appear loaded but stop playing after an event sync

Stability

• Fixed a crash that prevented events from launching on Snapdragon-based devices (e.g., certain Surface Pro models)

This release focuses on major reliability improvements for event management, smoother touch-screen experiences across the booth, and a polished sign-in and account flow — along with important fixes for photographers migrating from dslrBooth v7.

Event Management

• Resolved a significant slowdown when opening the Event Management screen on accounts with many cloud events — the event list now populates quickly and opening events is much faster
• Fixed an issue where events created during a session did not appear in the event list until the app was restarted
• Fixed an issue where cloud-only events (not yet downloaded to the current machine) could not be deleted from the Event Management screen
• Fixed an issue where, on a fresh install with an existing account, the Event Management screen only showed newly created events instead of the full event history
• All template thumbnails in Event Management are now displayed together in a grid, eliminating the need to scroll horizontally to see them

v7 Migration

• Fixed an issue where photo layouts and welcome screen images were lost when importing events from dslrBooth v7
• Welcome screen images and images attached to capture buttons are now correctly uploaded to the cloud when migrating events from v7
• Fixed a migration issue where background layers could be assigned an incorrect file path (pointing to a zip archive instead of an image)

Touch Screen

• Improved touch scrolling throughout the app, which had stopped working after the .NET 9 upgrade — dragging to scroll now works reliably on all touch-screen setups
• All guest-facing selection screens (photo templates, effects, backgrounds, digital props, and post-capture effects) now support touch panning, consistent page indicator dots, and smooth prev/next navigation

AI Portraits

• Updated the AI portrait selection and generation screens to use a dark background, providing better contrast for mirror booth setups
• Fixed an issue where the AI portrait style thumbnails were cut off or partially hidden
• Added the ability to deselect an AI style so photos can be captured without AI processing applied

Settings & Navigation

• Fixed an issue where maximizing the settings window hid the back arrow and "Launch Event" button, leaving touch-screen users with no way to return to their event
• Removed the unintended text shadow from the Print Setup settings panel that made text difficult to read
• Fixed a 1-pixel gap between the title bar and the top menu

Sharing & Account

• The Subscribe and Upgrade buttons now automatically sign you in to the website, so you no longer need to log in again in the browser
• The share status page now opens in the LumaBooth dashboard instead of the legacy fotoshare.co site
• Fixed the sign-in window so that password characters are visible, pressing Enter submits the form, and focus moves correctly between fields
• Fixed an issue where long event names in the navbar dropdown overlapped the download icon

Stability & Connectivity

• Fixed an issue where the app failed to sync cloud events when launched without an internet connection and then reconnected — events now load correctly once connectivity is restored
• Fixed an NTP time sync failure that occurred on machines where the network resolves time server addresses using IPv6, which could prevent events from syncing correctly
• Fixed start screen videos stopping playback after a cloud sync completes

This release focuses on improving the quality and accuracy of AI Portrait enhancements, giving photographers better results with less processing time.

AI Portraits

• Improved AI Portrait enhancement quality by automatically cropping tightly around detected subjects before sending the photo for processing, helping the AI focus on the people rather than background space
• Resolved an issue where slow network connections could cause AI Portrait requests to be incorrectly reported as cancelled rather than timed out
• AI Portrait images are now resized and optimized before upload, reducing processing time without sacrificing result quality
• The AI Portrait API now receives the correct aspect ratio matching the template's photo slot, improving how enhanced portraits fit into your layout
