Technique: I injected artificial nectar into the flowers so this male Drone Hoverfly would have a reason to let me get close. Male cause there isn't a gap between the critters eyes.
Tech Specs: Canon 70D (F11, 1/125, ISO 200) + a Canon EF-S 60mm macro lens with 25mm of extension + a diffused MT-24EX (flash head "A" set as the key and "B" as the fill, both on the Canon flash mount). These are single, uncropped, frames taken hand held. Camera set to use natural light to expose the background. I shaded the subject so the only significant light source for it would be the flash.
