I'm really chuffed with how these came out. Following advice in a very useful post in another thread on here, I shot these with an IR72 filter and set the shutter speed to 4 stops slower than the unfiltered meter reading at my chosen f stop (f11). There were a couple shots that I really wanted as 'keepers' so I bracketed a couple more on each of them, giving them 5 and 6 stops over the non filtered readings, but in these cases the 4 stops over was still the best. All shots are straight out of camera except the one second from bottom. That one got a slight rotation to straighten the monument a bit and a slight lightening, but that's it.
