What's New in Trichromy

1.6.1

November 8, 2025

Trichromy 1.6.1 fixes French localization bugs. -- Trichromy 1.6 introduces a number of improvements: BETTER CAMERA PICKER: Including support for Fusion Camera such as the 2× on all iPhone 15/16/17 series, and 8× on iPhone 17 Pro. NEW CAPTURE FORMATS You can stick with JPEG, or now choose HEIC (smaller file size) or TIFF (lossless quality, very large file size: ideal if you're going to print your images or use them for art projects) A NEW, OPTIONAL LIQUID GLASS THEME if you're on iOS 26 and you want bouncy, shiny controls, you're in luck!  The app icon also now behaves better with clear/tinted modes. SUPPORT FOR LANDSCAPE SHOOTING The interface will now reorient when holding your phone in landscape, and the correct EXIF metadata will be written. ENTIRELY FREE APP The watermark options were previously locked behind an in-app purchase; that is no longer the case. The app is now entirely free, and includes a voluntary tipping system. AND ALSO a number of smaller quality of life improvements such as support for saving the GPS location of the image in its metadata, a French localization, the ability to keep the viewfinder corners square, bugfixes.

Love using this app, results are awesome.

Amazing hidden gem

This app is so cool. It was a surprise to me to learn that trichromy was a photograph technique of the past. You can get so many great results

Really fun!

This app is really fun! I love messing with the settings and getting some really unique photos. Adds a lot of fun and spontaneity to my photography. Also, the developer has created other really good apps for photography! They really have a handle on what makes for a good photo app!

Thank you so much for your support and kind words!

100% recommend

Great idea. Ok execution.

The speed slider is very difficult to grab and operate.

The slider is also far too close to the main shutter button, meaning it is very easy to press the main shutter button whilst trying to use the speed slider.

This is very annoying because you have to wait for it to take three different photos before you can try again.

Would love to see this fixed in a future update.
