The photographs were taken under cloudless conditions the
afternoon of 13 July, using a 35-mm lens, with Kodachrome 64 film, F-stop=11 and 1/125th
of second. Transparencies were scanned to 4-MB TIFF files with a Polaroid Scanner,
and the digital images opened in Adobe PhotoShop, tilted to parallel, brightness-adjusted
+35 units, contrast adjusted to +30 units, uniformly cropped, and sized to 380 pixels
width, and black plot borders added. PhotoShop files were optimized with Ulead
SmartSaver to JPEG quality level 60, no smoothing. |

Originating from Texas, this greens grass is reported by
the developers to have 2.6 times greater lateral stem development than Tifdwarf.
There is a web site devoted to Champion, http://champion-dwarf.com/ The grass originated from Coastal
Turf, Inc., Bay City, Texas. It appears to have been released commercially in 1996,
based on a selection by Morris Brown in 1987 from a Tifdwarf green. These four
replicated plots were planted at University of Florida - Fort Lauderdale in May
1997. Throughout most of their evaluation they were mowed at 1/8 inch. Plots
were aerified the week of 21 June 1999 and were treated with excess rates of herbicides 29
June 1999 and again 7July 1999, thus the cumulative rates were actually 2X, 4X, 6X, 8X,
and 10X. Mowing was suspended as soon as treatments began.
