Nitro 2026.07.02

I just released a bug fix update to Nitro. You can get it on the App Store via the Updates tab or by going to this link. If you have problems with the link, then search for Nitro Photo in the App Store.

If you are going to be installing macOS 27, you definitely want to get this update, as it addresses compatibility issues with macOS 27 (Golden Gate).

These are the changes:
* Support for Sony RX10 V.
* Fix bug with Recover Highlights where the slider values would not be remembered
* Fix bug when scrolling the grid where the image was sometimes also selected.
* Work around bug in macOS 27 when reordering keywords.
* Work around crash in macOS 27 when exporting.
* Work around bug in macOS 27 when reordering adjustments.

I’m working hard on another update that adds support for Apple’s RAW v9 decoder, and other features added by Apple in the “OS 27” versions.


Nitro 2026.07 and more

There are new updates to Nitro and RAW Power available now. Make sure you get 2026.07, rather than version 2026.06, which had a bad bug.

The big news for Nitro is a completely rebuilt masking interface. The old one was powerful but hard to use. Now, it’s more powerful and much easier to use. Here are a few highlights:

  • New masking list with enable checkbox, and mask reordering.
  • Directly create luminance and color range masks.
  • Feather any mask, including AI Subject masks and luminance masks
  • Add or subtract an AI mask from a linear or radial gradient mask
  • Control the threshold when using the edge-following brush.
  • Bracket keys ( ‘]’ and ‘[‘ ) to change brush parameters.
  • More on-screen controls for gradients, including shift-key to constrain.
  • Brushes now have Flow as well as Strength, and improved algorithms for combining brush strokes.

Please watch the Masking Tutorial Video to learn more about it.

In addition, there are many bug fixes and usability improvements, including better undo in Edit, improved support for smaller screens, and a smarter straighten tool.

Since I last posted on the blog, I made many other improvements to the app:

  • Significantly faster initial display of images and metadata
  • Right-click (Mac) or tap and hold (iOS) to change font size in Info and ExifTool
  • iPhone: Greatly improved Curves interface
  • Faster keyword filtering
  • Brand new, super-sophisticated Perspective tool, integrated with Crop and Straighten
  • Duplicate Image command
  • Multiple Watermark support
  • AI Eraser to remove objects

The road ahead:

The next significant update to Nitro is focused on the “27” versions of macOS, iOS and iPadOS that are coming in the fall. The current OS 27 betas are buggy with Nitro. For example, many adjustments don’t work properly, including Levels, Curves, and the AI Eraser. Performance in some areas is bad. Beware!

For Nitro, the feature headliner is RAW v9, the first improvement in RAW decoding for Apple in several years. Not all cameras are supported yet, so there will be a transition (and it requires OS 27). RAW Power will probably not get RAW v9, but I will revisit that decision after I add it to Nitro. I’m also looking into Liquid Glass for Nitro – Apple is making it increasingly difficult not to adopt that appearance and it’s a considerable effort to adopt Liquid Glass.


Nitro 2025.10 (Mac Only)

I released a new update to Nitro (2025.10) just for macOS.

  • Fixes the annoying horizontal line that shows up on macOS Sequoia (it’s a macOS bug)
  • Enables tagging on macOS Tahoe (it was working then it broke, and now it’s working again)
  • Addresses an issue with Tahoe again when editing images and then quitting right away

I’m working hard on the new Retouch system, but I decided to get these fixes to people right away.


RawBridge has shipped and what’s next

RP 3.5 and Nitro 2025.7 have shipped with RawBridge, which greatly improves RAW decoding and lens correction for compressed Fujifilm and Nikon HE cameras. RawBridge also enables even faster new camera support.

I’m about to ship updates to both apps soon – mostly bug fixes, but Nitro for Mac adds a feature that lets you zoom into images with a scrolling mouse. These should go out the week of September 15th. These updates also fix problems using Finder Tags on macOS Tahoe.

You may be wondering about Liquid Glass and RP / Nitro. I started working on it when it was first made available to developers in June. However, the OS 26 builds have been very buggy. Even the shipping version of the OS has serious bugs that affect Nitro when Liquid Glass is used.

I filed plenty of bugs. Then, rather than spend the rest of my summer constantly fighting with beta OS builds, I focused on RawBridge and other features. I will resume my Liquid Glass efforts later this year. I don’t expect major changes to the way the interface works, but there will probably be some. The tricky part is making those changes while maintaining compatibility with older OS versions. I will say that I dislike Liquid Glass from a legibility and general usability standpoint, but some adoption of the look is necessary.


Exciting Camera Support Improvements Coming

As you know RAW Power and Nitro have exceptional camera support. Far better than other apps that use Apple’s RAW, including (and especially) Apple Photos.

It’s about to get even better.

The main downside of the additional camera support is the lack of automatic lens correction, which requires you to use the apps’ manual lens corrector (though the apps learn from your corrections).

In the near future, both RAW Power and Nitro will gain automatic, profiled lens correction for compressed Fujifilm and compressed Nikon HE/HE* images. I’m still working on the details, and also on how to deal with existing images from these cameras that have manual correction.

Do you use compressed Fujifilm or Nikon and have manual lens corrections? If so, I would like to hear from you so that I can get the migration just right. Email beta@gentlemencoders.com


Nitro Localized Keywords Update

The new Nitro keywords feature provides over 1000 localized keywords in six languages. Now that people have the app in their hands, they have found some incorrect translations (some >very< incorrect :-). Some customers have volunteered to correct the keywords and those changes will go into the next update. If you are reasonably fluent in Japanese, I would appreciate your help with that language. Please email support@gentlemencoders.com. Thanks.
