I wanted to be sure to share this, as it has been very useful to me. I was looking around for focus testing charts, something more comprehensive than the small ones I’ve used for years and found this.
I sent the file to a local print shop and had them make a large copy about 30” wide as well as a more portable 12” version. I had them mount them on foam core. It has been super useful, and it was only about $30. Having a consistent well defined high contrast target makes focus testing much easier. I can shoot a few test frames, duck into the darkroom and 40 minutes later have focus confirmation (or not!).
