.acr files showing up in Bridge

With the latest update (ACR version 14.0) .acr files has begun to pop up in Bridge - and as far as I can associate it's always when a mask has been created with the new masking system.

Se attached screen copy. The arw file above the .acr file - showing the same name - is featuring a number of masks.

    Unless the option has been selected, for DNGs, to embed XMP data, for both RAW files and all others, sidecar files are visible in any system browser. As for XMPs only, they may not necessarily contain masking information. They contain any kind of RAW parameter and can contain ALSO masking, until we get to the ones obtained by using Ai.
    So as long as the masking is
    - gradient (radial / linear)
    - brush
    - range (color, luminance) *

    ... everything still remains contained in XMP alone.


    When we go to "select subject" and "select sky" (October 2022) then the .acr file appears.

    I hope it was useful to someone 🙂

      Hi

       

      Thanks for the feedback. .acr are new sidecars in ACR 14 which contains masking information. We have added their support in Bridge 2022. It seems like you are using Bridge 2021 with ACR 14 and that is why they are visible as older Bridge does not recognize .acr as a sidecar file. Also please check that View->Show Hidden Files is not checked.

       

      Thanks

      Bridge Team

        Hi kpulkit (?),

        I didn't know I could run an older version of Bridge while subscribing to Creative Cloud with it's continuous updating.

        But you are right, I was running Bridge 2021, and after installing Bridge 2022 the .acr files seems to have become invisible. Hope it's permanent and the .acr files will follow renaming without problems.

        It would have been nice with this information up front.

        Thank you.

        Best,

        Hi Eigil,

         

        Yes, you are correct. The .acr file is a new sidecar file (along with the xmp files) that hold the information of changes made to a raw file. In specific, theses files hold the information of the new masking capabilities.

         

        There are  some peculiarities with these files: normally if you change the name of a file, the name of the xmp file changes as well but not with the .acr files. So you may have to manually rename them.

         

        Probably the easiest way around these issues is to just convert the files into the DNG format which are container files (like the jpg and tif format). That way, both the xmp and .acr files are contained within the DNG file and are never lost and move with the file. FWIW, I've been converting my raw files into DNG for many many years and have never looked back.

        Hi Gary,

        All right - a new side car. Not what I had expected with an improved interface.

        I also think these .acr files act strangely. When I think a couple of days back I have used the new mask feature more than six times, but I have only observed the .acr file 2-3 times.
        So, minutes ago I made a new mask in a raw file that had no masks in advance - but no .acr file turned up in Bridge. Then I made the same change in the tif file via the camera raw filter - still no .acr file. So, it's interesting what it takes to actually get an .acr file to pop up.

        Regarding dng vs raw. I think you mentioned the advantages with dng not long ago in another discussion. And actually I did convert some of my arw files to dng for about a year ago after having read an article that convinced me about the more universal design. But I still had the feeling of loosing data. My 60 Mb arw files typically ended up at half the size as dngs, which of course is great if you want to save disk space. My primary concern though was that the difference in size could be due to an actual loss of data and not just a consequence of a more effective conversion. This worry was confirmed when I found a utility called "A7 Info" for Sony A7 cameras. It can show where the focusing pattern was positioned on the subject when the image was taken. Was the lens focused on the key spot or not? That's an interesting question if you shoot a number of images and nothing but the focusing points have moved. That utility could not be used with the dng versions, as no focusing patterns could be derived. So that's a reason for me to stay with the raw files.

        Best,

        Eigil

        Hi Eigil,

         

        Couple of things: as I had stated above, the tif format is a container format so any xmp or acr sidecar files will be inside the tif file. Think of container files as a folder.

         

        The reason for the decreased size of dng files (one of the benefits (but not always, read on)) is that there is some zip-like compression on the contents. Some files decrease a small amount others more. There is generally no loss of data BUT as you found out the focusing point is an issue. The problem here is that Sony, with many raw format creators, is very proprietary about THEIR format and will not release the necessary information to Adobe, or anyone about this feature. Otherwise, Adobe creates what they do by "backdoor" methods so as to not violate the copyright of Sony and others. 

         

        There are many who have Sony cameras who do convert (to DNG) and many who do not. There is no right or wrong. Like all of photography, it's a compromise. Sorry I could not help you more.
