""and since I'm about to do some low level photography on Friday, It just got me wondering....
""
I can think of at least two fatal accidents caused by PPLs doing precisely this including the mid-air over Wales which killed the Jaguar Wg Cdr who had undegone transplant surgery and got himself back to flying fitness. FWIIW my advice as a former air trafficker would be don't do it.
Now as a lawyer I would suggest that if the photography is in any sense commercial it is air work and beyond the privileges of a PPL; if it is "low level" can you maintain ANO mandated separation from persons, structures, objects?
Standing by to get flamed...........
