Once a black image is created, I clicked on File> Add Layer(s) From File, and used the Quick Mask tool (yellow arrow on left) to "paint" a line around Gui Lian. The Quick Mask tool wasn't sufficiently precise in blacking out all of the targeted areas, so I also used the Masking Brush tool (red arrow) and went over these areas on complete the task....a task that took me no more than 12 minutes; well within my range of tolerance. I then pumped up the saturation using Iridium Developer tools...a task that took under a minute.
A pretty picture is not enough. It needs to be high quality and it needs to be original. For magazines, you need to consider issues such as leaving space on the image for word placement, positioning your subject off-centre so it doesn’t fall down the page join, and possibly placing the subject on the right-hand side of a landscape shot for maximum impact.
