Halong Bay - Vietnam

Do you think this picture would be good enough to make a poster? Where

can I find a publisher?

Pierre, finding a publisher depends upon your ability to pay for the quality you want. SE Asia, specially Singapore, and Hong Kong had good publishers for large format books and posters years ago. Quite a lot of landscape calendars are printed in SE Asia.

Nice image but missing the punch. A wide angle

scenic would benefit from a central point of interest, like if you could move *significantly* closer to people by the shore. You could either use a telephoto from where the same location, or WA but move closer. The blue color works well.

Superb photo! The horizon needs to be leveled since it is water, it can't have a slope.
