Nice shots. I do agree with goldenlight that they needed a bit of brigtening up and the altered images are very good and I love the proportions in the first shot.
Great to have colourful beachside cabins. A photo opportunity that screams out "take me". While Sydney is a seaside suburb with more than 70 beaches, we don't have anything like these. I guess the locals got over the modesty thing a long time ago (actually, tey just drive to the beach in their swimers or shed their outer clothes on the beach.
These are classic shots of their type. An investment in some graduated neutral density filters would be a wise choice particularly the first one where a hard 3-stop or similar Reverse GND would work wonders.
Thanks John, if it wasnt for you I would never have tried to change them. What I would say though is lifting the shadows is creating noise, is this normal?
