Opening a single image for editing is not a feature in Nitro. It might be something I add in the future, but I don’t know. It’s a bit odd because of the non-destructive approach (there is no explicit Save).
Thank you David for the kind words. It’s been a long road (2+ years) and I’m glad that people like what I’ve built.
Soft-proofing is on the list, but it’s not on the near term list.
As far as versioning, I have some ideas about that. For now, if you duplicate the image in the Finder, AND you are using APFS, there is no disk space consumed, so that is a good way to go.
Yes, that works the same way. The extension works with whatever library Photos has open. Apple allows Photos to open any library. They just don’t let anyone else!
RAW Power can only open the System Photo Library, and Nitro is the same way.
You can switch the library by going in to Photos Preferences and changing the system library. Then open Nitro.
Changing the system library will pause iCloud Photo Sync, but it won’t cause the libraries to merge.
I did not add a way to purchase the app before the trial is over. I should do that but I didn’t want to bug people every launch or so. I’ll see what I can do. Because the trial is completely unlocked, I figured it wasn’t critical (since you don’t get additional functionality by buying it).
Hi Ben,
Right now the app doesn’t have the ability to write metadata out.
Are you asking about adding / removing some of the metadata in the ExifTool view, or in the regular view?
Yes, that makes sense. BTW: if you have a trackpad or a Magic Mouse, you can pan that way as well (move your finger on top of the mouse’s surface).
The prices are visible in two places:
1) If you download the app and view the prices in the paywall (View Options)
2) In the App Store description, there is a section called Information with In App Purchases. The prices are listed there.1. Are the edits saved in text in the XMP sidecars (like with Darktable, which is fantastic in this respect)? Hence, there are no huge Edited Copy Files created of the original raw files in edited form? I don’t like unnecessary copies of images stored on disk. Just keep the edits in text in the XMP.
Yes. Edits are stored in XMP as plain text.
2. When using with Apple Photos, are the Nitro edits shown in Apple Photos? And if yes, is that only because double the disk space is being consumed in order to keep a full size copy file in the Photos Catalog? Again, as per Question 1, I don’t want that.
Yes they are visible in Photos.
And No. It stores a full size JPEG or HEIF, but not a full size RAW or TIFF. A full size image is required by Apple.3. When the iOS / iPadOS version of Nitro is out, will it also have the ability to work outside of Apple Photos, just like the Mac version, and work directly on the raw files with XMP sidecars to carry the edits in text form, and no duplicate images? This is partly related to your comment here. Will I then be able to do a lot of iPad editing on Nitro when travelling (for months), all the edits sit in small XMP sidecars with the original raw files, then I get home and simply copy over to Mac the entire folders of original raw files plus small XMP sidecars, and open them in Nitro on Mac and see all the edits?
Yes. You will have to rebuild the preview images that are used in the grid and viewer because the XMP files do not contain that data.
4. Is what I call the “messy” set of conditions still there, where it is hard to wrap one’s head around when Apple Photos shares the original raw file for external editing, and when it sends a JPEG or other less pure option, …is that still there? You once gave a long and convoluted explanation of this, which I *appreciated*, but struggled to keep in mind when it is or is not happening, because it is invisible to the end user. This messiness contributed to my moving on from Raw Power. My fault, but if you can clarify and simply the situation with Nitro, that would be great.
If you want full control over your files, then don’t use Photos. I don’t think Photos has changed how it works with external editors. Nitro has an external editor function but only for files not stored in Photos.
5. Final question: my experience with Raw Power was plagued with crashing. Especially when batching. One case was batching an image edit to a large number (hundreds) of other images. Another case was batching a large number of raw files to an exported format eg JPEG. Can you assure me that those were specific issues that won’t turn up with Nitro too, please?
No, I cannot (and will not) assure you that there will be no such bugs in the app. RAW Power is much better about that than it used to be, but it’s not perfect. Nitro is not perfect either. Massive batch operations on iOS are generally going to be an issue due to the limited memory model on that platform. That said, I try hard to fix those bugs.
The luma and color noise reduction is part of Apple’s RAW decoder, and only work for those types of images. Unfortunately, I do not have a way to hook them up for non-RAWs.
Nitro’s auto white balance code is trying to find a patch of color that /should/ be gray, but isn’t. Sometimes it fails to find one (due to limitations in the algorithm). In that case, it cannot find the white balance value and it displays that message.
Lifetime purchases get all updates for free. There won’t be a break at major versions.
That’s because Nitro won’t have versions like 1.0, 2.0. It will use a “year.version” notation, like 2024.1 and eventually 2025.1 with continuous improvement.
