There are quite a few threads about Yvon's focus charts so I've had some difficulty picking a thread into which I can place some info.
I've chosen this one.
I printed up Yvon's charts and mounted them on wooden blocks. The blocks have T-nuts inserted in the bottom so they can be used either on a table or on a tripod.
The wooden blocks for test charts 1 and 2 are cut at 45 degrees. The charts were stuck down with spray on contact cement to avoid water based adhesives which would bubble the paper.
The larger chart is on a large sheet of timber and has a 45 deg wedge to support it.
My pics are pretty bad but you get the idea of how I have used them. The tripod mounting makes it much easier to view the chart and to adjust their height. I may take some better pics later today.
