Block Paving - Photogrammetry based Environment Texture

Surface of old paving blocks, surprisingly very hard to tile.
This time for measurements I used plastic folding ruler. So far I have found it more useful to measurement tape, since values are easier to read and ruler itself supports vertical surfaces.
I used monopod to stabilise the camera during this capture. With the focal length set to 24mm, f/8 and ISO100 I managed to get average exposure time around 1/10sec .. which sucks imo. I feel like I almost finished my 'monopod for photogrammetry' research and hopefully soon my photogrammetry ebook should get the update with conclusions.
