Can you please try to take some photos like this with your phone.   Having photos like this will allows me to prepare and to get more done when we meet. You will need someone else to hold the ruler for the first and removes it for the second.

- no rings on your hand

- hand over white paper

- fingers loosely together, like the photo

- camera directly above (you might have to work around a shadow a bit)

- one photo with a ruler in the same position as the sample

- second photo without the ruler trying not to not move the camera.  We want the photos to look the same other than the ruler missing in one.

- let me know which finger the ring will be worn on (if I have sent you here for anything other than a wedding ring)

- email me the photos in as large a file format as possible

Have a go and if you we need to take them again we do.
