When photographing in the bluebells it is important to stick to the paths so we don't trample all over the lovely flowers!
The trick is to sit your subject on one path while you move to another path and get down really low! This give the illusion of sitting in the bluebells but you're actually sitting on the path! Its like magic! A gorgeous portrait lens such as a 50 mm, an 85 mm or a or a 70-200mm zoom lens works super well! and use a wide a wide open aperture to get that lovely blurry effect!
Give it a try!!
