Greenlawn-Centerport Hist. Posted October 22 Share Posted October 22 I'm trying to decipher the faded handwriting on an 1840s schoolbook for a historical society. I've tried messing around with the contrast levels, trying high pass and color burn, but nothing has made the handwriting legible. Any advice on what settings to try would be appreciated!

paleolith Posted October 22 Share Posted October 22 You might try photogrammetry. This article is about deciphering grave markers, which have similar problems, but might be applicable, especially if there are indentations from the handwriting. https://agleryl.notion.site/Virtual-grave-rubbings-using-photogrammetry-8e43483f9c464192961cbb492608a82c Oufti and NotMyFault 1 1 Quote Link to comment Share on other sites More sharing options...
NotMyFault Posted October 23 Share Posted October 23 The contrast is so low that the limitations of jpeg make it impossible as the relevant small details are removed. Only chances is to do a scan with 16 bit capable scanner and save as tiff (uncompressed or lossless compression), or take a RAW image with good camera and lens. RAW must support 12-14 bit per color channel. then, experiment with lighting. You need a good light source with HQ white light. (CRI) and high color temperature (cold light) If possible can you upload a RAW file, or the current file zipped to avoid further quality reduction by the forum app?
