@Sonia Rampling A focal length of 600mm no image-stabilisation and a shutter-speed of 1/2 of a second gives you, when you are lucky, this kind of texture. You don’t need to move your camera consciously, just try to hold the camera steady (without a tripod). But be ready for a lot of crap images. And a little bit of post-processing is although involved. Dehaze and contrast is your friend here
