A “technique” I discovered – If yo u place the flash perpendicular to the lens, with some of the light shining into the glass of the lens, it produced this blue, washed-out effect that gives photos an interesting finish. I obviously emphasised the effect a little in Lightroom but the original looked pretty much like this, possibly with a little less contrast. I’ve yet to try this out for portraits.

An important thing to note is that here, the flash is on the right side of the frame, not pointing at the thistle but at a brick wall which was behind me, so the light is bounced and goes across the camera lens on the way to the wall. See the below Paint masterpiece for an explanation.
