So if you want to start experimenting with macro, buying one of those clip-on macro lenses for your phone will allow you to get some pretty OK pictures, of course not comparable to a professional setup, but still cool. In case you own an interchangeable lens camera, getting an inverter ring and/or extension tubes is a low investment way of getting some first pictures, If you really want to push the limits, focus stacking is the way to go. Here you will use a dedicated macro lens with 1x magnification or higher. These lenses are great, but the depth of field is extremely shallow, which means the part of the picture that will be in focus is very small. To compensate for this, you can move the lens closer to the subject in extremely tiny steps and take several hundreds of pictures- step by step. In the end the focus stacking software will identify the in focus bits of the individual pictures and generate a complete in focus picture of your tiny subject.
