This seashell was taken with stacked shots at larger than life size. There are three types of macro: 1) pseudo macro, what most of us call macro but is really close-up photography. It seldom if ever gets to life size shots. 2) Macro, the real thing, This results in photos where small things are larger than life (e.g. over 1:1), and then there is extreme macro where images are 5 times life or more. This photo is are over 1:1, less than a centimetre of shell filling the frame (cropping does not change magnification). It’s a project to help avoid boredom during the pandemic. I don’t pretend to be an expert. I have had many failures and still working for the best results.
