New Zealand flax again, plus full moon and scuds, in an image combining flash with background moonlight. To use flash in this way, start with aperture selection. This means finding the f-stop that fits your camera distance, as the flash has its own inherent shutter-speed. Then extend your actual shutter speed until your foreground/background balances out in a nice Goldilocks exposure (not too bright, not too dark). Unusual effects will show, for example, when your foreground sways in the breeze in the post-flash part of the exposure. The resulting slight double-image is just one more random element in long exposure photography, adding to its interest and creative potential.

85mm, ISO 2000. 1.3/sec at f9. Flash
