I’ve just googled it and I’m gonna try it out…I dont know if youre into photography but I basically shoot with an aperture of f1.8 with my 50mm lens orr an aperture of f3.5-5.6 with my 18-55mm lens…as I’ve never been taught photography I dont know particular techniques beyond what I read when I started out…and now I dont read many magazines…I just go out and shoot as often as possible…but as soon as it gets sunny in London I’m gonna deffo try it out
