I'M LEARNING MACRO PHOTOGRAPHY. Lets learn together,..

Option1
The closer you get to your subject, the larger your subject becomes and the more depth of field you need. Set your aperture number higher and work with less light. In this case we can change the ISO value. If we set this higher, we create light again. (Do not set the ISO value higher than half of the maximum value! The photo will be blurry !!!) (I like this manual settings the best !!)

Option2 (also mobile phone!)
Try to be a little further away from the object.
Then more of the object will be sharp. Not only the front of the object will be sharp !! Wait until the focus is on the object and take the picture .. (or tap your finger on the focus where the focus should be.) (If the subject is in the middle of your screen, it will be in fucus)
