  • Can I remove the dots

    The photo below is one of three schoolchildren taken at the same time and all have the same problem. They have lost their colour and have various other damage. The one attached is colour corrected which still could be improved.

    The main problem with them all is the green dots covering the whole photo from the grainy texture of the paper. It is not noticeable on the original, but highlighted by the scanning.

    Can I eliminate these at scanning or is there a way of reducing or removing all together in Photoshop?


    The photos are approx. 35 years old

    Any help would be greatly appreciated.

    Thanks

    Colan

        Re: Can I remove the dots

        Here's some good first steps:

        • Duplicate the image
        • Convert to CMYK
        • Copy the cyan channel to a new layer in the original RGB image
        • Invert the image of the new, copied layer
        • Change the blend to Color dodge
        • change the opacity to 50%
        • Merge the layers
        - See left image below for results to here
        • Duplicate the layer
        • Run the hIgh Pass Filter at 1 pixel
        • Invert the image
        • Change the blend to Vivid light
        • Adjust the opacity to 50%
        - See the right hand image for the results of the inverted high pass application .. a bit softer

        With some cloning and patching you should be able to produce a showable photo.

          Try scanning at a 45 degree angle if not move it around and scan it again..I bet one of your scans at dif. angles will get rid of the paper texture.
          Anyway I:
          Cut out the background, ran it thru Noiseware, healed the skin in parts, painted some of the spots out, heal patched the sweater...added noise everywhere.
          It normally helps to present the original image or scan (before corrections)

            ran FFT filter
            ran neat image filter
            used grain surgery 2 to sample grain from original
            matched grain at 57 percent
            made mask of girl copied to a new layer
            replaced background with white.

              Hi there

              As the good work above I ran the picture thru Image Analyzer to remove some of the texture.

              Then some healing brush...replaced background then a good amount of noise filtering. I may have used a little too much on the sweater.

                Hi Everyone

                Thanks for taking time to help and offer advice. I will try each one to see the difference and save the methods used for future reference.

                One other question, what method or plug-in does you use to get such clear crisp extractions when changing the background?

                Thanks again

                  It's always a good idea to post the original along with your reworked version.
                  Because you're only posting the image you've already adjusted, you're missing out on techniques that might better handle the problem if applied to the original color image.

                    Hi Vikki

                    Thanks for the info, this was my first post. I will also post original in the future. I am new to this forum and looking through the other posts I am astounded with the depth of talent and variety of different methods used by the members. I feel very lucky to have found this forum.

                    Regards

                      Re: Can I remove the dots

                      I used the GML (search this forum for it, it's a free extraction tool) for the top half and the pen tool for the bottom half.

                        With the original high res I'm sure you can get a much better outcome.

                          Hi,

                          Colan,

                          welcome to RP!!

                          What Vikki said about posting the original scanning too....

                          ..I think scanning at different angles helps a lot in minimizing this kind of patterns.... this Tutorial shows you how... But, if re-scanning isn't an option, Photoshop will help you get very good results.

                          Like unimatrix001, I used the FFT filter on your picture. Here is the archive page of Alex Chirokov creator of the free FFT Plug-in for Photoshop.

                          I have both versions, but tend to use the RGB version of FFT/IFFT because it gives you the same results and it's simpler to use ... You can find Rô's Tutorial on the usage of FFT here.

                          Attachment 1 = my final result.

                            Hi Flora

                            Thanks for the warm welcome. Your version is amazing, I doubt if I 'll ever get close to your standard on the other two photo's, but I have downloaded the fft filter and will practise and hopefully learn at the same time.

                            Could you tell me the other proceedures you used and how do you get the extraction so clear and accurate.

                            Thanks

                            Colan

                              I'm sure you will ... Just don't give up ....I was about to throw my computer out of the window when i started with the FFT Filter!!!

                              ... very simple... I didn't extract at all!!! ... I simply restored the original background after having created a (not very accurate) mask around the subject > Attachment 1.... As for my procedures here they are: (I work with Photoshop)
                              • used the magic wand to select the Background.

                              • with the selection active (marching ants around it), I created a Level Adjustment Layer where, to remove the cyan cast, I tweaked the Reds only as in Attachment 2

                              • After that, I created a new blank Layer and set its Blending to Color.. with a fuzzy brush (Opacity 30-50%), sampling colour from surrounding areas, I painted over the discolorations in the girl's face, hair and top. You can find a Tutorial on this procedure here just scroll down the page to the "BLANK/EMPTY LAYERS SET TO...." paragraph.

                              • I used the Patch Tool to remove the scratches.

                              • I used Neat Image (a Noise Removing software which comes in 2 versions: as standalone only (free) or with the addition of a PS plug-in (not free))... Neat Image can be downloaded here and on the same page you will find the links to manual, support, tips and tricks..

                              • I used the Heal Brush to clean the spots on the background.

                              • Finally I lightly sharpened the girl by using Filter>Sharpen>Unsharp Mask.


                              Hope this helps ... but just 'yell' if you need more help..
