my advice is revisit the old places. you will start to see them differently, in different light. for example , i have been to lower peirce many times throughout the years. this isn't because i have nowhere else to go. i haven't been to raffles marina in a while, and i would like to go back, but lower peirce is a favourite location with so much to work with, just along the rocky stretch.
...
each time was different for me.. and that's what shooting landscapes has become to me. about getting the right mood for the lighting. a far cry from the earlier days when i just shot for the sake of having pictures, i guess.
