Hey @matkodurko, I know - but reward comes with a little risk, right? :) The wall is probably a bit deeper than it looks on the photo, but I think those two cameras have already had the fear of heights drilled out of them by now!
You're right - I should probably have made it clear that these steps are really incremental - from (1) through to (5) they build on top of each other.
Thanks for reading and taking the time to comment! Happy shooting :)
