I have not been real happy with my macro flash shots on some of my moth photos. I have a Nikon D90 with a 105mm macro lens. I have been using my built-in flash, my hot-shoe flash, and an added RayFlash ring attachment. Some of you have incredibly sharp close-up shots that I would like to get. Do any of you use the dual flash attachments for close-up shots? If so, and you are a Nikon shooter, which one do you use? I've seen different models at different price ranges. Thanks for any advice!
