Dear Friends, this is a composite image resulting from 40 images taken with macro lens and a focus step approach, even at f16, the depth of focus was not sufficient to render all the details in this tiny group of green crystals, so i step focused with my Camranger and put the images together with photoshop, this tiny crystal cave is an area of about 1 square mm and the color of the rock around the crystal was a surprise, do you like? til Tomorrow MJ
