jegog Posted June 25, 2018 Share Posted June 25, 2018 Scanned microfiche documents can be very noisy and generally a pita to process. Can anyone suggest a workflow to process them to reveal the wanted information. Preferably the written information with a light yellow background. I have included a sample jpg file. On the righthand page near the top is Elizabeth Rice 80 and at the bottom the family of Isaac Rice 55 with wife and 4 children. Quote Link to comment Share on other sites More sharing options...
Staff Dan C Posted June 25, 2018 Staff Share Posted June 25, 2018 Hi jegog, Welcome to the forums! There are a few ways you can do this, I've attached a file below to show the effects I used to try and best bring out the text in your image. I used a selective colour adjustment, changing to 'Whites' in the dropdown list then adjusting the colour and opacity until I was happy with the yellowish tint. I then used a combination of a High Pass Filter with the blend mode set to overlay, as well as a brightness & contrast, shadows/highlights and levels adjustment to bring out the text. Hope this helps Genealogy.afphoto John Rostron 1 Quote Link to comment Share on other sites More sharing options...
jegog Posted June 25, 2018 Author Share Posted June 25, 2018 Thanks very much. This is one of the worst I have come across. But having that banding of over development creates problems. Quote Link to comment Share on other sites More sharing options...
Staff Dan C Posted June 25, 2018 Staff Share Posted June 25, 2018 If by 'banding' you are referring to the darker bands towards the lower half of the image, there is not much that can be done to eliminate these as they are part of the original scan and will only intensify as you turn up the contrast and high pass adjustments!

jegog Posted June 26, 2018 Author Share Posted June 26, 2018 Yes, the microfilm processor's squeegee between the developer and fixer seems to be dirty. I redone it by converting to 8bit colour and using the noise filter before the high-pass filter. Dan C 1 Quote Link to comment Share on other sites More sharing options...
