Hi there, I hope I can help with this. I use a more advanced camera now so I might be a bit rusty. I got this bit of info below off the web to help explain the portrait program which is selectable on the round dial on top of the camera just rear of the ON/OFF switch.
Vari-program: Portrait
Use for portraits with soft, natural-looking skin tones. The camera selects the focus area containing the closest subject. If the subject is far from the background or a telephoto lens is used, background details will be softened to lend the composition a sense of depth.
Depth of Field is basically how much of the picture is in focus.
For the B&W and pink champagne its done on the computer. You need to have graphic software lots around some expensive others cheap and some free.
