This clip was filmed as part of a One to One training day with Mike Browne. Focus the camera on a bunch of window panes. There is a row of window panes which cuts across the bottom left hand side corner. There's actually nothing right or wrong with it, only thing that matters is whether or not it works for you. Mike Browne believes that because it is strong and dominant you should crop the image so that it will no longer be visible. You can always remove that in a computer later, thanks to digital photography, but it is recommended to leave less to remove later on. Simply cut out the bottom portion of the picture and you will get a more balanced image.
