Hopefully these photos will be self evident, but, OK if not ask a question and I will try to explain as best I can... the objects that are resized are the subject here, them being unseen with human eyes.... only illuminated by the infrared laser which has a distance reach of 3,000 meters (3km) and focal width adjustment of around 30 M at the tip...... estimates only (using your Maths) will show you approximately the sizes (scale) of the objects... so please be reasonable and don't say.... "bird, bat, insect etc." and show your ignorance... thanks. ....................
