  • Removing scanner stripes

    Hello, everyone.

    I scanned a few old pics and noticed that all of the images have a vertical line with bright pixels. I think this is a problem with the scanner (maybe some reflection in the scanning bed). In any case, all the solutions I've tried to minimize this have failed, so I was wondering if I could just remove this bright stripe using Photoshop.

    I have attached a small crop out of one of the images where a vertical bright band of pixels can be seen in the center. I am trying to get rid of this using Photoshop. Any help would be greatly appreciated. Thanks.

    The healing brush or the patch tool should help, but IMO you should really be addressing the scanner problem as you are just making work for yourself

      Yes you can remove these stripe lines in Photoshop. You just need to select those portion with a selection tool and then need to adjust that portion with the remaining portion.

        I presume you have already tried cleaning the scanning head - assuming that the lines are showing up in the same position on each scan? It only takes a minute bit of dust to cause problems.

          Getting the scanner fixed and re-scanning is by far the best solution.

          One approach in Photoshop is to make 2 - 4 different scans of the photo with a different orientation on the scanner. Crop and rotate them to the same orientation. Load them in as separate layers (File/Place embedded). Then you have 4 identical layers with the 'damage' in different parts of each layer. Align the layers (google how to do this) and hopefully you'll be able to remove the damaged part of each layer to make the undamaged version of an underlying layer visible.

          Another approach is reducing the patterns/stripes using filters.
          A free plug-in called 'Fast Fourier Analysis' (FFT) is often recommended for reducing regular patterns in photos, for example caused by scanner reflections of photo texture. This is complicated and time-consuming too. I've not had much luck with stripes though.

          I recently tried Dfine2 which is part of the free Nik plugin collection. It's intended to reduce noise in photos but it did a pretty good job on stripes too. It also reduced the fine details too so I added these back in with the history brush.

            How can you tell if your scanner is behaving?
            by Donamai

            A friend of mine gave me a BearPaw 1200TA scanner that he bought and never used.

            I am very new to scanning images for composition and I have never used scanners in the past so I am not current on how to use them correctly.

            I have never paid much attention...

            I've begun to notice gray decolonization on my scanner preview screen. You can see this in the attached image -- the gray line along the left side. This showed up on preview, then I scanned a larger part of the screen to show it in this image (waiting to be restored). On preview it actually shows...

            OMG There is an ant farm in my scanner!
            by Elleth
            I haven't used the scanner in a couple of weeks. I just now opened it to make a scan and there are 1000's of ants inside of it...OH MY GOD!!!! I am totally freaked out...I have a really clean house and I never eat near my computer equipment, why would they make a nest in the scanner? I'm afraid the...

            How essential are scanner specs
            by pavel123
            I apologize if I am asking an obvious (to anybody else) question.

            I have a relatively old scanner (going 5 years or so back HP ScanJet 3400, it wasn't a high end scanner at that time). Can say I am happy with the quality of scanned images. Colors are off, images seem darker (which is a...

            Finding a scanner's "sweet spot"
            by G. Couch
            Most consumer grade scanners have what is known as a "sweet spot"- an area where the scans will be at their sharpest, and with the least amount of noise. For most scanners this a narrow area running down the middle of the bed, but it can vary greatly from scanner to scanner. Higher end scanners...
