Just a quick tip this time. We all know how great certain subjects can look when seen in black & white rather than color.
Just about every digital camera is capable of creating a black & white image, but please resist the temptation to do that. This is only my personal recommendation, but always shoot the original image in color. Why? Because the image may look just as good either way, but if you shot it in black & white you will never be able to retrieve the color. The black & white image saved by the camera will have no color information in it.
It is easy to convert a color image to black & white on your computer. Many cameras will let you do the conversion in-camera and create a second image in black & white (leaving the original color image intact). But if you didn't shoot in color, you'll never get color — unless you want to spend untold hours and money on special software or services to try to recreate the image in an approximation of the original color.
