F\/11? That, I find, gives the best balance of definition and depth of field. Smaller apertures introduce diffraction and definition begins to fall – that’s physics, not Canon. Wider apertures at close distances result in very shallow depth of field – appropriate for plane, perpendicular surfaces only. ISO seems to end up in the range 100 to 400, which is the sweet spot for the 5D’s sensor. Nice!<\/p>\n
Reflections of the tube in the ring flash can be an issue – though the sort seen here<\/a> just enhances the sense of curves.<\/p>\n Occasionally, with reflective subjects, you get a nasty image of the flash tube reflected in the subject, like so:<\/p>\n I do not know whether the enhanced localised processing controls in Lightroom 2.0 could fix this – I”m still on 1.4.x and await 2.1, presumably suitably debugged. In the meanwhile, it’s back to that old dog Photoshop (Lightroom has a direct export and save function) and a few seconds with the Magic Eraser:<\/p>\n That’s more like it.

The ring flash I have been using on the 5D with the 100mm Canon macro lens is proving to be a real joy. It’s pretty much set and forget. All I do is adjust ISO to procure an f\/11 aperture with the camera on shutter priority and 1\/200th (the fastest … Continue reading Ring flash<\/span>
