How can I get the formatting of a field in one worksheet to transfer to subsequent worksheets within a work book.

You can't link formatting between cells, with a formula or otherwise. You also can't format the result of a formula as you require - that's only possible with constant values.

If the contents of the source cell aren't going to change then copy and paste the formatting to the subsequent sheets.

You can group the sheets and do the paste into all sheets in one go:

Copy the first cell, select the second sheet and select the cell where required and then press Shift and Select the last tab where required. Then Paste Special - Formats.

If the sheets requiring the format are not one after the other, use Ctrl + click to select each tab rather than Shift + click on first and last.

Then select the first sheet to ungroup the sheets.

Yes, Camera tool would be an option.

The only downside that I could see with that is if the source cell changes size rather than any other formatting. The size of the image changes in line with the source cell but it does change the size of the cell where the image is overlaid.
