Ursula, I thought about your question about getting detail on whites and yellows when I took this today. Your gift Euphorbia x lomi is blooming. It had lost all it's leaves but now they are back and happy with it's new home and watering schedule so the flowers have started blooming. I decided to take a pic in indirect bright light at f8 to start and go up in f-stops if the details didn't show (slowing the shutter speed so the aperture is open longer to register more details). There would be more chance of loss of sharpness though since I was handholding the camera. If I get blurry pics at f8 I would have used a tripod and a remote shutter release to keep the camera really steady. Turned out f8 was fine.
