I have a number of photos in which I need to make the image on the computer (or printed image) equal to the actual size of the object.
For my research I am looking at a number of tooth photos and need to measure their surface area. In each photo I included a centimeter scale. So in photoshop I am able to calibrate the measuring tool to reflect the size of this scale and thus the actual size of the object. I know the calibration works because I am able to get the same linear measurement in photoshop as I did on the tooth itself. (Just for reference, my centimeter scale seems to be equal to 10cm on the rulers included at the top of the image in photoshop).
What I need to do now, is to find a way to have the image on the computer, for example my centimeter scale, equal to an actual centimeter. Or in other words, be able to resize the image to a 1:1 scale. I need to be able to print images that are the actual size of the object. Or better yet, determine the 1:1 ratio and then be able to enlarge the photos (before printing) so they are exactly 5x the size of the object.
Sorry for any confusing language, I am new to photoshop. Any help on this matter would be greatly appreciated.
