It's sand for goodness sakes. What do you expect?? The stuff is grain and what with the black bits washed up on the white sand it looks even grainier. I can honestly say this is the best, least grainy film called polypan-f around. Look at the snaps with a squint and they look even better. But not as nice as when I saw them on Traigh Mhor the other day when the sea had retreated so low.
