I find the best time to photograph things in the garden is just after the rain. The overcast light is consistent with no distracting shadows. The raindrops clinging to the flowers and foliage add a lush look impossible to capture on a brighter, sunbaked day.
Colours look more intense and vibrant in the shade. Even better, this tulip has more graphic appeal closed. When it is open in the bright sunshine, the petals are open and flopping about willy-nilly. Closed up, the delicate red edging provides a nice highlight.
