Yea sorry about that my phone camera as been messing up for awhile now all it does is bring out blurry pics I'm not sure how to fix that
It's not the camera. It is the light and either the way that you crop and edit? Or the distance you take the photo.
It is individual to the camera you are using. First try to stabilize it. Then find out the distance that the coin is in focus. Move the lights, they should start at 10 and 2 , but that is not mandatory. Too much light will hinder the definition of whatever you are photo'ing. It is going to take some practice. PS get as close as you can with out using the zoom. Then after you photo the coin crop out everything but the coin. The zoom function will add too many pixels.
