I have been talking to some old school friends and one of them mentioned the school photo that was taken in 1961. In order to have a really good look during our next Zoom meeting I’ve scanned it at 400dpi. My scanner can’t take anything that long, so I did it in 4 sections and those are shown below. However, I couldn’t leave well enough alone, so I decided to combine it back into one photo using Photoshop, and then exported it to a .pdf so I could pan the photo and zoom in on the details if I needed to. I was amazed to see that the whole photo turned out to be 43 megabytes and the pdf is 186 meg! Each of the original jpegs is less than 2 meg, so it shows how much extra stuff goes into photoshop files and pdfs!
