I think it’s time I had a go at Robyn’s very cool One Four Challenge again. My first entry, in November last year, used a poolside photo; this time I’ve gone for a photo of roses that I took in New York’s Central Park in May this year. My first edit is dramatic, but simple: colour inversion followed by a 50% reduction in luminance noise to give that silky look. My plan is to bring the image closer to the original each week. But we all know what happens to plans!
