I took these in London’s Hampstead Heath with a few friends of mine who are photography enthusiasts too! Very minor editing was done in post and only one image had been focus stacked as the subject was just too small to capture in one image.
My kit - Canon 600D AKA T3i, reversed Canon 1970’s 28mm f2.8 and a 12mm extension tube.
As for light I simply used the on board flash with a home made diffuser which bounced and diffused the light.
My kit is very light and produces great results so I am able to carry this around with me all the time in the case that a macro opportunity occur :)
