        Re: Ft Pattern Suppressor

        This is a 64 bit version which works on 8, 16, or 32 bit per channel data. Please try it and see if you have any problems.

          Updated to version 2!

          This thread got taken down for a while, but it's back. Just in case I moved the downloads to ft.rognemedia.no, but you can keep the discussion going right here in this thread if you have any problems or questions.

            Just extra tips to people scanning old photos they intend to restore, remember the old saying of "crap in = crap out". So here is a couple of things I recommend you do at the scanning step of the process to give yourself a great starting point:
            • Scan at very high resolution. 300 is usually too little. It's best with a bit too much (especially if you intend to use this pattern suppression). You can always reduce the size later (but not the other way around).
            • Make sure no color values are clipping! In other words, no color value should reach 0 or 100% (255 in 8-bit) because this means information is being lost and color correction (and pattern suppression) will be harder to do well. This might mean your raw scan will be a bit low contrast, but that can be easily adjusted later.
            • Scan in RGB, 16 bits per channel (48 bits per pixel). This will increase accuracy of your colors/adjustments, and you avoid banding issues (especially if doing heavier adjustments).
            The above are more on the software side of things. I'm sure some scanning experts can come with some other practical suggestions as well. Here are some other practical suggestions:
            • Make sure the image you are scanning is clean!
            • Make sure the scanner glass is clean! Dust and fingerprints show up on the scan...
            • Calibrate the scanner if you have the means. This ensures more accurate colors.
            • If scanning a picture that has a bit of "3D" structure on the surface, this structure might be exaggerated due to the angle the light in the scanner hits it. To compensate you could scan the image at multiple orientations and merge them. Alignment here will be critical. I have not personally tried this as I don't have any suitable images.

              Looks like no one noticed. They don't know what they are missing.

              Website looks super and video is top level for a free program.

              For scanning old photos, I always place a large heavy book on top of the photo to make sure there is a coupling with the glass. Kind of book might be a coffee table book which is larger than the photo.

                Hi Ron and Chain

                Thank you so much for working on this action and its latest version 2 update - its excellent and it works beautifully. I followed your instructions and watched your very clear video tutorial, downloaded everything. I then tried the action on a high resolution TIFF scan that I had first converted to grayscale (the original was an old grayscale print but I scanned it in colour and converted to grayscale first). I then ran the action on the flattened version grayscale image. The original was full of annoying horizontal lines and the action worked brilliantly first time! I found in this instance I didn't need to use anything other than the normal setting.

                Out of interest I tried this action on another print which I had previously tried number of other texture removal options(including neat image), but this method was by far the most successful.
                Chain your scanning tips are also excellent advice for old photos/prints.

                For reference I am running Photoshop CC 2018 on Windows 10

                  Thank you for the positive feedback. Good to hear it's working for more than my test images.

                  By the way, there is no need to flatten or convert the image to Grayscale before processing (although it does no harm). The actions actually start by flattening and converting the image (back) to RGB.
                  Sometimes you might have some paper tint or something in the image that you want to keep available (in case you want to re-apply it later). By keeping the image RGB this will be preserved on your original (on the background layer) even if using the "Grayscale" actions.

                    That's really helpful to know that you don't need to flattern the image first Chain. I did wonder about using the colour option - I might try that as I have about 6 of these line art "photos" (150 lines per inch ). In this instance I don't need to retain the tint - I just like to get as much information as I can in the original scan, but running the colour option would allow me to retain the information and then channel mix later. They were big TIFF files too which I would never have been able to use a few years back - another reason why I am so impressed with the work you guys have done.

                    Note just tried the colour option on my RGB monotone lined photo image and it worked well too!

                      In my experience testing this action (what feels like an infinite amount of times, although with only a few test images), you get equally good quality with the grayscale (luminosity only) and color actions. But if I do not need the color information I prefer the grayscale version just because I find it a little bit easier to see what is going on with the vertical line. The slightly more painting/masking needed takes an insignificant amount of time anyway (unless you are doing a large volume of images).

                      We could have included only the "color (per channel)" version and still got a good result in all situations that we have tested, but we wanted people to have a couple of processing/workflow options in case of tricky images or personal preferences.

                      ---

                      Anyway, just wanted to mention that WE JUST ADDED MAC-PLUGINS TO THE DOWNLOAD!

                        Hi all - I've tried downloading the files from the < http://ft.rognemedia.no/ > site but get no response hitting the downloads button. I'm running Windows 7 with Photoshop CC installed. Could the Windows version I have be causing the problem? Let me know - am very interested in getting this pattern supressor working since I'm working on scanned vintage photos. Thanks!

                          Jeff,
                          Both seem to be working OK for me. Win 7 should not be a problem with downloading or executing. Please try the Download Now button and might take a while as it is on DropBox. If not working then try this: https://www.adobeexchange.com/creati...ls.100742.html which is Adobe Exchange. We just updated to v2,5 with Mac usage.

                          Please get back.

                            Hi Ron - As it odd as it may seem, when i left clicked on the button, there was no response. But then I tried a right click, chose "Open Link in New Tab" in the dialog box that opened, which then opened the Dropbox page that then opened another dialog box and gave me an option to download the file. All OK so far and on my desktop. Will install when I have a moment and will follow up with you. Thanks again for the incentive to take another shot at it!

                              Probably an issue with an adblocker. We have an event trigger for Google analytics on the buttons to count the number of clicks/downloads. It is possible an adblocker might interfere with the functionality.

                              Whitelist the site and refresh. It should work fine.

                              Ps: There are no ads. Just basic google analytics tracking so we have an idea how many people are using it (mainly because Drive/Dropbox does not show us how many downloads the file has).

                                Hiya - agree on the adblocker. Opened IE instead of Firefox and download button worked. Program is loaded and in place. Now to do a bit of practice. Thanks Ron and Chain for the additional backup and support!
