What the macro setting on your camera essentially does is focus on a very small area. The background often appears unfocused to further bring out your intended subject. Getting in close to capture all the detail of a small object is nearly impossible with the regular setting on a camera. Anything closer than about three feet becomes blurred. The macro setting changes the distance your camera will be able to focus and often allows you to take clear pictures from as close as two or three inches.
This camera mode allows for a lot of experimenting. Try taking a picture of a bee sitting on a flower petal or a close-up of frost on the window. You will be amazed at the details brought out. You will be able to almost feel the furriness of the bee and the ice crystals are beautiful.
If you are planning to sell at online auctions, a macro setting on your camera will help with taking better pictures--and better pictures help with sales. You can take close-up photos of such objects as stamps and coins, show the engraving on an object or allow a viewer to see that a piece of jewelry is flawless.
Don’t save your photo taking for big events exclusively. Take a walk and notice the little things like the pattern on a tree trunk or an ant carrying a bread crumb twice his size. There are interesting photos everywhere once you start to look, and the macro mode on your digital camera is the perfect tool for capturing them.
