Drawing 4 is divided into two sequences, top and bottom. This was the first drawing done, and so there was a lot of extra data taken in testing. The first two series (d04___00 - d04___26) were done without refocusing in between filters. This proved not to work well, so the next two series repeated the first focusing in between filter changes. The accuracy of the numbers is kind of suspect, as this was the first series and things weren't well worked out. The numbers provided are those recorded, with no attempt to see if they actually make sense. The first top series settings were: Inclination: Distance: 0 degrees unmeasured File Filter Gain Flash (1/x) d04___00 d04___01 d04___02 d04___03 d04___04 d04___05 d04___06 d04___07 d04___08 d04___09 d04___10 d04___11 d04___12 2 3 4 5 6 7 8 9 10 11 12 13 142 10 20 6 10 8 8 6 6 6 6 6 10 14 1 1 1 2 2 2 2 2 2 2 4 4 4 The next file was taken with the tape measure in the picture. d04___13 5 10 4 The first bottom series settings were: Inclination: Distance: +1 degree unmeasured File Filter Gain Flash d04___14 d04___15 d04___16 d04___17 d04___18 d04___19 d04___20 d04___21 d04___22 d04___23 d04___24 d04___25 d04___26 2 3 4 5 6 7 8 9 10 11 12 13 14 14 14 24 8 0 10 8 8 6 6 6 0 6 1 1 1 1 2 2 2 2 2 2 2 1 1 The settings for the second top series were: Inclination: Distance: unmeasured unmeasured File Filter Gain Flash (1/x) d04a__00 d04a__01 d04a__02 d04a__03 d04a__04 d04a__05 d04a__06 d04a__07 d04a__08 d04a__09 d04a__10 d04a__11 d04a__12 d04a__14 d04a__15 d04a__16 2 3 4 5 6 7 8 9 10 11 12 13 142 2 3 4 ? 20 4 8 8 8 6 6 6 6 6 10 6 10 20 14 1 1 1 2 2 2 2 2 2 2 4 1 1 ? ? ?
