MACRO SETTING OR LENS
While you can use a mobile device's digital camera at the standard settings you can often see much more detail by using the macro setting on the camera. A macro setting changes the focus of the camera so it can focus on very close objects. The macro setting is for photographing objects within a few inches or feet away. My phone's digital camera has a macro setting that works within one centimeter, to get very close shots (light can be an issue when you get that close). You can use the macro setting to improve your ability to see small details, similar to using a magnifying glass. You might want to use a small tripod to hold the camera steady. Don't forget to change away from the macro setting when you are finished (if the phone's camera doesn't do it automatically). If the camera is set at macro and you are trying to take a normal picture then the focus will be set wrong and the image will be out of focus. I know of one teacher who took a few pictures up close on the macro setting, and then forgot to change back to the normal setting, and she used up a lot of her device's memory space with the pictures all out of focus.
With the macro setting you can often get so close that you create a highly magnified image without any accessory lenses. Use the macro and get a glimpse of worlds that you may not have noticed.
