Since this flower was blowing around and vibrating, I need a fast shutter speed (1/250th) with the 100mm macro at f4 after sunset. I underexposed a lot at ISO 200 and pushed the processing from ARW using ACR 4.6, by 2.3 stops plus extra brightness, vibrancy and clarity (but not saturation). It's a noisy result without anything more than ACR default NR but I like the colour and the bokeh. The A900 viewfinder makes shooting this type of subject a real pleasure even in poor light.
