I have tried various things in PS but don't seem to get anywhere. This one was of my grandfather, and published in 1963. I'm just starting a project to scan numerous family photos and know how much of a challenge that can be. Maybe someone else out there has actually used Focus Magic or the Topaz tools and can offer specific advice on using them. Sounds like you would still want to start with the "Descreening" filter in your scanning software. I'm guessing that Focus Magic does much the same as Sharpen AI, and Denoise AI might work really well with the halftone dots. I haven't tried it, but it might be worth trying it or Topaz Denoise AI and/or Topaz Sharpen AI. His fourth recommendation is an application called Focus Magic. These preserve the detail and tonality much better. Second he recommends using the Gaussian Blur filter or the Box Blur filter in Photoshop. First is the Dust & Scratches filter in Photoshop, which will lose considerable sharpness and shadow detail but may be worth trying if you already have access to Photoshop. In a book entitled, "Digital Restoration From Start to Finish," by Ctein (no first name), he suggests four methods of getting rid of the halftone dots. These filters will not eliminate the dots but will soften them significantly. My Espon scanning software has a "Descreening" filter with three options for "General," Newspaper (85 lpi), Magazines (133 lpi), and Fine Prints (175 lpi). Check your scanning software for "halftone" or "descreen" settings. Some scanning software includes a filter to help "descreen" the halftones (i.e., remove or reduce the dot pattern). Newspaper photos were published using a technique called "halftone" where the picture is made up of a fine pattern of dots that, from a distance, look like a continuous tone. Making a copy which is larger than the original will mean larger dots with no increase in sharpness. Your exposure in copying can affect the apparent size and sharpness of the dots. You perceive the effect of grays because of the relative sizes of the black dots. The dots are only solid black or solid white, the histogram should be two straight lines (black and white) with nothing between them. If that is the case, remember that there are no grays in the image. If not, you’ll be stuck with trying to copy the halftoned image. If you can get the original continuous tone print you are miles ahead. If they have gone out of business, ask the largest newspaper around you, and any local historical society, if they might have acquired the morgue files. If they have the original photo that the printing plate was made from, then they probably can make a copy for you, for a fee. Large newspapers keep these things filed away forever-or until they go out of business. Have you contacted the newspaper to see if they have the old original, or a clip, in their ‘morgue’, or reference library?
