I have a boatload of pictures, some even from pre-1900s. However the ones that my scanner seems the struggle with the most are the ones from the 1910s or around there that have a reflective coating to them that you can also see in person when viewing the image. This makes it really hard to properly scan these images even though they are very high quality due to being film and I want to create copies since they are my ancestors. My scanner is the Epson Perfection V19 II and I have played around with a lot of the picture settings but have not found solutions. Some of the pictures come out better than others with reflections only being around the corners but others are completely unusable making it impossible for me to scan the pictures at all. Are there any other strategies I can try for these types of photos to capture them the best digitally?
