My equipment is essentially just a dedicated macro lens for my Olympus camera and a set of Neewer extension tubes. For lighting, it is natural light or a small Godox TT350 flash on my camera shot through a small diffuser that I hold on my lens. For indoor studio setting, I use 2 flexible LED end table lights. Sometimes I have painted backgrounds with my iPhone and various colours on my screen. Also I like to tether the camera to my computer when possible.
