I've been trying again to capture a decent image of my iris. This time I'm using the Nikon P900 with the Raynox DCR-250 Macro Attachment.
I can certainly get closer now, but the image is a little soft and grainy as I ramped the ISO up to maximum to get a short shutter speed. Next time I'll see if I can get any more light so that I can drop the ISO setting.
