I have taken some photos (with my phone) of some optical phenomena in the lab. I'd quite like to analyse the distances between some features of the image. In school I remember using a piece of software which allowed you to choose an origin point / setup coordinate axes, select a scale (i.e. 1 cm real life = x pixels) by using a reference length in the image, and then determine distances by clicking between points. Might anybody know what this program is (or a similar program that I could use)? Many thanks.
