You need to get your Nikon down to an insect’s level for this…
01 Set it up
First, find a clump of flowers (or cheat and buy a pot yourself) and position your Nikon so that it’s looking up at your subject through the petals, giving the impression of a very low point of view, just like an insect’s. You’ll probably need to lie down to check the composition if your Nikon doesn’t have a flipout screen. Ask your model to peer down at you through their magnifying glass.
02 Tweak exposure
Focus on the magnifying glass and the eye closest to you. One potential problem with fisheye photos is overexposure, as so much of the sky is in shot. Check your images and dial the exposure down if needed. Shoot in RAW so that you can easily crop away the black borders in postproduction.
03 Get creative
There’s no end to the silly shots you can take. Shoot from above and give your subject a huge nose or eyes, or place them further away from you; they won’t be distorted, but the landscape around them will be warped. Add a blue or green cast in-camera or in Photoshop for the look of an extraterrestrial portrait.
