This is a good learning point for me as well: I should have included a picture of a filter. Good point! There are different types of filters, they either screw on to the lens like this one or you need a frame into which you insert the filter, like this one. And there is the new Canon R camera that allows you to insert a filter behind the lens, but you do need an adapter for this to work.

Actually, there are also neutral density filters for phone camera's. I have never used one, so I cannot tell you how good they are, but you might want to check this.

It is indeed very difficult to choose the right camera, there are so many good camera's out there today. Hmm, sounds like this could be another tutorial topic. Who knows I will write about different camera's in the future. For now, just keep in mind that it is not the camera that takes the picture, but the person behind it. Even with a phone camera, you can make awesome photos!
