Travelled to Seville for a two-day conference. Took telephoto for birds, of course, but had only my iPhone 6 for general use. Here is a view across the Guadalquivir River through the window of a restaurant and then one at the end of the meal (1/15s, iso 2000. f/2.2). The daytime is straight out of the phone, reduced about two fold, and the night similar but noise reduction using Nik.
