Frequently asked questions

When can I buy the apps?

Both applications are in active development and are headed to the Mac App Store. If you'd like to know the moment they ship, email info@archiveoptics.com with the subject “Release updates” and we'll notify you personally. We only use your address for that, see our privacy policy.

What will they cost?

Pricing will be announced at release. What we can promise now: one-time purchases, no subscriptions. Software you buy should stay bought.

What Mac do I need?

Both applications are built only for Macs with Apple silicon (M1 and later).

• Negative Converter needs macOS 15.6 or later.
• PhotoLibrarian needs macOS 14.6 or later. Two of its editing tools need macOS 15 for their machine-learning models: on macOS 14, denoise is not offered, and the healing brush copies nearby texture only.

Which files does Negative Converter open?

Scans saved as TIFF, JPEG, PNG, or HEIC, and camera RAW files from Nikon, Sony, Canon, and Fujifilm (NEF, ARW, CR2, CR3, RAF), plus DNG. RAW files are decoded by macOS, which can't read a few files from supported cameras.

Will importing my Lightroom catalog change it?

No. PhotoLibrarian opens the catalog file strictly read-only and never writes to it, and your image files are cataloged in place, nothing is moved, copied, or modified. Lightroom keeps working exactly as before; the two can coexist for as long as you like.

Does any of my data leave my Mac?

No. PhotoLibrarian and Negative Converter have no network access, macOS itself blocks them from connecting to the internet. Every machine-learning model runs on your Mac, including face recognition, focus analysis, healing, and denoising. Nothing is uploaded, nothing is shared, no account, no analytics.

Files that live only in the cloud. If an original lives only in your iCloud or Dropbox, PhotoLibrarian asks first, and macOS downloads it from your own account. Negative Converter never downloads a scan that lives only in the cloud: it marks it “Online only” until you download it in the Finder and add it again.

How do I get a refund for Negative Converter?

Apple handles refunds for Mac App Store purchases. Request one from Apple at reportaproblem.apple.com.

Are updates to Negative Converter included?

Yes. Its license includes every update to the major version you bought, at no extra charge. A future major version may be offered as a separate purchase.

Is there a manual for Negative Converter?

Yes, and it's built into the app: choose Help › Negative Converter Help. It's illustrated and searchable, with lessons on real photographs, and it needs no internet connection. The license agreement is there too, under Help › License Agreement.

I found a bug. What should I send you?

Email support@archiveoptics.com with what you were doing and what happened.

• Negative Converter: include the version and build shown in Negative Converter › About Negative Converter, and, if you can, the scan that shows the problem.
• PhotoLibrarian: its View › Logging window can export an operation log as text, attaching it helps us enormously.
