Comma, Polygonia c-album

Another bit of an experiment with fill-in flash to give extra light and hence depth of field. With this kind of pose and natural lighting it is hardly ever possible to get the DOF required to get all the butterfly in focus. However, use of two Nikon mini-lights and aperture priority at f/16 can do this, even with a 180mm prime macro lens. Although shutter reading is nominally 1/60th, and the shot is hand held, I think it closes off earlier due to the flash lighting.

No need to say much about the butterfly, as most of us Europeans know it well. This picture is more about lighting than biology.

The picture has been cropped and rsized in Photoshop Elements and selectively sharpened.

Hi Alan,

This shot has worked well, light above and below the subject has kept the colours uniform and no over saturation or blowout. Focus good and fine from wing edge to far wing. Well done and TFS

regards Bill

Hi Alan,

Thanks for the tips. The f16 aperture makes wonderfull DOF. That flash and a tripod are often what one forgets to pack and are so important.

Hello Alan,
I think that interesting to know what others use technique for macro photo with good result. You get very good result enough deep DOF and without visible shades.
Regards, Pawel

Hi Alan. An interestin job do well with the flash lights. You have been able to get good detail and focusing along with rich colours. I like the POV so we can see the wing markings. Well done TFS.
Nick..
