Dear friend,

my name is Anders and I’m the CEO of Brattoo Propaganda Software and I would like to personally thank you for being our valued customer. With this short email I would like to tell you about the status of our product Duplicate Annihilator and also a little about the migration to Photos from iPhoto and Aperture. I hope that you you will find it interesting.

Duplicate Annihilator

13 years ago we developed the first version of Duplicate Annihilator for iPhoto and it has certainly been a pleasure helping people in over 170 countries to get rid of duplicates. Over the years we have added more and more functionality but still keeping it simple thinking that iPhoto, Aperture or Photos is the main image browser and you should not have to learn new browsing tools.

Over the years the competition has grown but Duplicate Annihilator is still the only tool that weeds out imported thumbnails and face thumbnails, generated internally by iPhoto. A very requested and appreciated feature.

Many of you have requested a perceptual detection of duplicates. Especially those of you who have scanned the same photo at different times and created what seems like duplicates but do not share the same binary data nor the same meta data, they just look the same. We’ll over the years we have evaluated many algorithms and techniques to do this and found them all to insecure. But now, our engineers have developed our very own algorithm based on how the human eye and brain interacts and analyse images and so far the lab tests have been impressive. Expect to see this implemented in future versions of Duplicate Annihilator.


Last year Apple introduced Photos a replacement for the discontinued iPhoto and Aperture. There are many opinions about this. Some find Photos fast and easy to use and some find it buggy and that is lacks a lot of important features, especially if you who migrated from Aperture. When the first developer preview of Photos was released we were the first company to develop a duplicate detection tool for it, Duplicate Annihilator for Photos, and we encountered a lot of bugs.

The most critical bug we encountered was that Photos could fail internally when trying to set the Description and thereby not marking the duplicates detected by Duplicate Annihilator. This happened in about 10% of the cases with Photos v1.0 and v1.1 but it got better with Photos v1.5 and so far we have not encountered it in Photos v2.0. When we first detected it we made a bug report to Apple and now, about 18 months later, they have finally put some attention to it. So if you are one of those who still encounter this and would like to participate and help Apple resolve this then please reply to this email. We and Apple would really appreciate it.

macOS Sierra (10.12)

Soon Apple will release macOS Sierra and Photos 2.0 which also means that you will no longer be able to use iPhoto. Therefore we have recently updated Duplicate Annihilator for Photos so that we support the new macOS Sierra an Photos 2.0.


If you still use Duplicate Annihilator for iPhoto and would like to upgrade to Duplicate Annihilator for Photos we currently have a discounted upgrade program. For only $4.95 you can upgrade any old Duplicate Annihilator license to Duplicate Annihilator for Photos and for just one dollar more you can upgrade any old Duplicate Annihilator license to the Duplicate Annihilator Toolbox including a family pack which mean that you get five licenses for you and your family for all versions of Duplicate Annihilator including iPhoto, Aperture, iOS and Photos.
