Download them on the App Store (go to the Updates area on the Store). Both apps add support for Fujifilm X-M5, Nikon Z50 II, OM Digital OM-3, Panasonic DC-GX880 and Panasonic DC-S5D. Nitro adds a bunch of features including borders, more zoom options, and better performance.
I released 2025.2 with some important fixes and am now on 2025.3. That is in beta testing right now. I have started working on keywords, but that is a larger effort, and there is so much in this release already that it makes sense to get it to you sooner rather than later.

I’m pleased to announce that the Nitro User Manual is (finally) finished. If you have suggestions for topics or corrections, please email me at support@gentlemencoders.com
You can view the manual online here: https://www.gentlemencoders.com/nitro/user-manual/index.html
It is only in English, but I made it in HTML so you can use your browser to translate the text, though the images will not be converted, of course.
This is a list of the improvements that will ship in 2025.1.
# New Features:

* Duplicate Mask and Duplicate + Invert Mask.
* New Auto Black in Levels and Curves with a setting to switch back to the old algorithm.

* Add Sort options for the sidebar.
# Usability:
* iOS: when brushing and zoomed in, you can now use the trackpad to pan around the image.
* Add Flag and Favorite commands to the Batch menu on iOS, and also to the contextual menu (iOS and Mac)
* Do not show a disclosure control for empty folders in file system and photo library
* Mac: Add more commands to the Image menu when in Edit

I updated the manual today with information on Presets, LUTs, R+J Editing, and Quick Fixes. I also added some navigation controls to make it easier to jump around.

I stopped posting on Twitter some time ago. I will start posting on Blue Sky. Here is the handle: @gentlemencoders.bsky.social
I’m starting up the blog again to give people a little more insight into what’s going on with the apps. Since I do not want to inundate you with emails, I will update the blog (occasionally) instead. If you have an RSS reader, you can get automatically notified when new posts go up. The feed is https://support.gentlemencoders.com/feed/
I am getting close to releasing the next version of Nitro, which will be 2025.1. It has a mix of new features, usability, performance, and bug fixes [which is the norm for my updates]. I have been releasing new versions more frequently recently, after a lull in the fall (which was due to pressing personal matters). My goal is to send out new versions every 2 months on average. Monthly updates are too frequent to add features of consequence – there is a lot of overhead in shipping new versions, so there is a tension between getting “real” work done and getting software to you. Hopefully that cadence + this blog will satisfy people’s desire for software and news.
As far as RAW Power goes, there will be an update to RAW Power with the 2025.2 version of Nitro that has some camera support and bug fixes.
You may not know this, but RAW Power is built by just one person (me). For the past two years, I’ve been working like crazy on a new app. And now, I am proud to introduce Nitro to you. Nitro is written from the ground up with the latest technologies, and its combination of flexible storage options, camera support, and editing tools is unmatched by any app.
If you like RAW Power, you’ll love Nitro’s fresh interface and immense power. I have been fielding emails from many of you for some time, asking for features like gradients, brushing, cloning, XMP sidecars, synchronized zoom, and more. All of those (and a lot more) are in Nitro.
Nitro comes with a REAL free trial. No strings attached – you don’t have to sign up for a subscription. After you try it, you can buy it outright, or sign up for an inexpensive monthly or annual plan. Check out the Questions and Answers below to learn more.
RAW Power edits are 100% compatible with Nitro. If you use the Photo Library, Nitro reads RP edits automatically. If you use the Finder, then get the RAW Power update to use the new “Export Nitro XMP Sidecar” feature.
Enough talk. Here is a 30 second video about Nitro for Mac.

Today, Nitro is available for macOS. What about iOS? Well, Nitro for iOS is coming soon! Your purchase of Nitro for Mac will also give you full access to the iOS version when it’s released. I’m looking for a small number of dedicated beta testers for Nitro for iOS. if you use RAW Power for iOS regularly and are interested, please email Nitro iOS Beta Sign Up. Note: I cannot accept everyone who applies for beta testing, because large beta groups are too hard to manage.
Questions and Answers:
Why did you write a new app / Why not just add these features to RAW Power? I initially wrote RAW Power in 2016 as a simple photo extension. iOS and Mac apps were separate worlds and the dominant Apple technologies of today (for example, Metal) either did not exist, or were immature. Fast forward several years, and now all of those things have changed. Apple has even moved to a new programming language! Further, the underpinnings of RAW Power have become an obstacle to advancing the app. For example, the RAW Power engine is simply not able to handle features like masking and synchronized pan and zoom. I decided some time ago to start fresh, even though that would take a long time, because it provides the best foundation for a great photo app in the future.
I hate app subscriptions! Not really a question, but so do I. That’s why Nitro has a completely free trial without a subscription signup, and a one-time purchase (lifetime) option. Nitro is more expensive than RAW Power because it does a lot more. (Apps have gotten more expensive in general to better reflect the immense effort involved, especially professional level apps.) The subscription options are there to provide flexibility: you can keep trying the app after the trial ends at a very low cost; and if you will use the app infrequently, a subscription (essentially renting it) is much cheaper than the one-time purchase.
What does this mean for RAW Power? RAW Power will continue to be maintained and offered for sale. It will NOT become a subscription app. It is less expensive than Nitro, and runs on older OS versions. I will continue to add camera support and fix bugs. You can get the update to RAW Power here.
What about other languages? Nitro is currently available in English, French, and German. I will also be localizing Nitro into Spanish, Japanese and Chinese (traditional and simplified) very soon. If you want to help evaluate the quality of the translation, email Localization Help Sign Up.
How can I ask you questions? Just email me.
Hi everyone,
It’s been a while since I wrote a blog post. Not due to a lack of topics. Just a lack of time. So, this one will be short.
I just released version 3.4.10 of RAW Power to the App Store. It has some new camera support and bug fixes.
People have noticed that the rate of updates has slowed considerably in the past several months and wanted to know why.
Well, I’m working as hard (or harder) now than I was before. The reason the updates have been smaller is because I’m working on something really cool (and large), which cannot be released piecemeal. I’m very excited about the opportunity to show it to everyone. But now is not the time.
When it is, I will be sure to let you all know. If you aren’t on the mailing list, I suggest joining it – that’s where the big news always is published first (and I very rarely send email, so it’s not something you are going to regret doing).
Here is the link to the Mailing List
