Dear friend,

My name is Anders; I’m the CEO of Brattoo Propaganda Software. When I wrote the very first newsletter, I told you how, many asked about the feature; detecting duplicates based on the actual contents of the photo. This is something we have worked on for many years and evaluated many methods and algorithms. Now, I’m thrilled to tell you that we have actually made it, and created an algorithm that seems to get the job done. I’ll tell you more about this later in this email, together with other things, which hopefully you will find useful.

Updates on Photos Tagger

In my last letter I told you about our brand-new application, Photos Tagger, which extracts all the hidden metadata about your photos and their contents from the Photos database and assigns it to your photos as keywords, making the organization of the photos much easier.

We have received a lot of positive feedback, but also some frustration that, Photos seems to tag the photos extensively with multiple versions of the same word such as “car” and “cars”, making the keyword list unnecessary long. This can be a bit tricky to handle, since we need to take care of all versions of all words of all languages. Our engineers have come up with a solution, that has solved this pretty well; and it is available in Photos Tagger v1.1.0. It is available today and you can download it from here:

Duplicate Annihilator – Perceptive Mode

I’m so proud to give you the all new Perceptive Mode in Duplicate Annihilator for Photos. Together with engineers and researches in the field of human visual perception, we have been able to develop an algorithm that detects duplicates, or very similar photos, based on what the photos “look like”. Let me tell you what is so fantastic about this.

Let’s say that you have two versions of the same photo, one resized and recompressed and one that is not. Duplicate Annihilator can now detect those as duplicates and it will keep the one with the highest quality as the original. Scanned photos have been a problem for many of our customers for years. What if you scanned the same photos in two different occasions? Now you have two scanned versions of the same paper photo, but different metadata and different binary data. But now, with Perceptual Mode, Duplicate Annihilator can detect those as duplicates.

Another interesting feature of Perception Mode is that, Duplicate Annihilator does not need access to the original photos that might be located offline or in iCloud. For Perception Mode, the local previews and thumbnails are sufficient for an effective detection of duplicates.

Duplicate Annihilator for Photos v2.0 with Perception Mode is available for download today.

Smart Albums and conditions

In previous newsletters, I wrote about Smart Albums in Photos and some good things you can do, to organize your photos. A small feature with Smart Albums which is often overlooked is that, when you use more than one condition in a Smart Album, then a new popup appears at the top of the Smart Album. That new popup defines if “any” or “all” of the conditions of the Smart Album should be met. And that can of course, have a huge impact on the result. So keep that popup in mind when you work with Smart Albums.

Smart Albums and wildcards

Smart Albums are actually searches made in the Photos database. Databases are great at finding stuff, especially when you know how they work. You can always use wildcards, when searching in databases; a wildcard is a character that basically means “any combination of zero or more characters”. This can be very useful in some cases; in Photos, the wildcard is the percentage character “%”. An example could be if you want a Smart Album that lists all photos which has a person identified, simply set it to list all photos where the “person is %”. Or the opposite, if you want to list all photos where no person is identified “person is not %”.

In Smart Albums you can in many cases, set the condition to “Starts with”, “ends with”, “is”, “is not”, “contains” or “does not contain”. But what if you want to search for something that start with the letter “i” and ends with the letter “a”? Well, you can’t, unless you use a wildcard and search for “is i%a” which will match all words that starts with “i” and ends with “a”.

There is actually one more wildcard and that is an underscore “_” which means any single character.

If you have any personal ideas or user cases on using wildcards in Photos, I would love to hear them.

Do you use Smart Albums? Then please let me know how you use them.

The free apps section

As I have mentioned in previous letters we have received requests on how to automate some tasks in Apple Photos or tasks related to photos. Those tasks might be tedious to work out manually but are easy for us to solve. The apps include a tool to set the Photos Titles based on filename (with or without file extension), a tool to copy and apply GPS coordinates between photos and finally a utility to set the correct file dates on image files based on the photo date stored in the metadata within the image files. You’ll find all our free apps at
