It doesn’t take a great camera, in fact almost any camera will do.  I have been using the Canon G7X II and playing with it to identify the techniques that enable me to make images that I would like to make.  I would like to make images like those above; i.e. up close and in B&W.  My problem isn’t having no camera nor is it knowing how to use it, nor knowing what I like.  The problem is, what do I photograph to make images in this style with this camera?
