Another visit to Rochester

I arrived in Rochester about 10:30 am and was lucky to find a car parking place available in the Castle Gardens car park.

This shot was taken from approximately the same place as on the previous visit to Rochester but this time using a new part to the pinhole camera having  a focal length or projection distance of 170mm, the pin hole was 0.5mm and there was a yellow filter and graduated neutral density filter used, exposure 5 minutes with f/ 340.

By moving back about 30 meters I used the same camera and set up and this is the result

By moving to a position adjacent to the car park this was the result  all camera and settings staying the same

Taken from within the Castle's Gardens looking towards to "old" Rochester Bridge, camera and all setting the same.

From the Castle's Gardens but this time looking up the River Medway, camera and setting the same.

So the calculation I considered to remove vignetting from the images and over exposed centre have worked ...  So what next ... well  how wide angle can I go before the overexposure in the centre of the image and vignetting becomes too noticeable. 

and just for a bit of fun
