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.

Re: Can I remove the dots

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)

Re: Can I remove the dots

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.

Re: Can I remove the dots

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

Colan

Re: Can I remove the dots

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.
