+ SCOPE Pictures from RUDAK Testing in Orlando

+
+
+
+ First-Ever 800x600 Images via RUDAK
+
+
+These pictures were taken on Sunday, 14 March 1999, in Orlando at the Phase-3D
+lab. There was a mirror propped up on top of the satellite over the camera
+lenses to give us a view of something other than the ceiling. The exposure
+times were 4 seconds, and these were taken with SCOPE B.
+
+The people in picture 4 are Chuck Green N0ADI on the left, and John Conner
+WD0FHG on the right. Picture 5 has Bdale Garbee N3EUA on the left, and John
+Conner WD0FHG on the right.
+
+The funny angle and I think some of the visual artifacts are due to the cheap
+mirror we used to take horizontal pictures with the cameras facing straight
+up, and to the large number of reflecting surfaces nearby.
+
+First, the BMP "Quick Pics". These are just as downloaded from RUDAK:
+
+
+Here are the raw data files from the image buffers for each:
+
+
+Each of the raw files was passed through the netpbm tool rawtopgm, which
+generated a portable graymap. This file differs from the raw file only by
+the inclusion of a header, so I won't bother with those files here. The three
+graymaps were combined to a color image using the netpbm tool rgb3toppm, which
+produced a .ppm file for each picture:
+
+
+
+These files were loaded into the GIMP, rotated or flipped (I don't recall
+which), and then written out as jpeg files with 100% quality:
+
+
+
+
+ Exposure Comparisons
+
+These pictures show the behaviour of SCOPE A. All were taken with the same
+lighing in the cleanroom, and are pictures of the ceiling. The flourescent
+lights were on, so the room was fairly bright. The lighting was essentially
+the same as for the pictures taken above. They seem dark to me.
+
+
+This set was taken on Sunday early afternoon with SCOPE A. They are mostly
+black. I think this was a 4-second exposure of the ceiling.
+
+We switched over to SCOPE B
+after this so that we could focus on getting full-resolution picutres out of
+the camera, and did not get time to take another full-res picture with SCOPE
+A.
+
+I include these files mostly in the hope that they might provide some
+information, not because I'm convicned that they mean anything.
