Piers writes “Daylight savings has started now, and it was still quite light, but not light enough, and I really needed to use a flash. The shadows cast from my built-in flash are really harsh and especially prominent in close-up shots, so I made a makeshift light diffuser out of the top of a slide box, lined on the inside with some thin paper. It worked pretty well, as you can see, the photos have a nice soft light.” Link.
