The following image contains two columns/series of pics taken of CYA tests. One series is a test of the 50ppm CYA Standard (R-7065) provided with the TF-100 test kit. The other series is a test of my pool water. I know which is which is which (I have a legend).
what I would like to do is compare interpretations/readings. In other words, in each column, which pic represents the "take this value" point?
(Each column is labeled from the top: L1, L2,... L7 for the left side; and R1,...etc for the right.)
For reference, here is a link to Taylor's CYA instructions with a few images of their test and what they indicate is a "reading": Taylor CYA Test.
I'll post the "answer" a little later (which column is the 50ppm Standard, and which pic contains the view tube filled to the "50" ppm line).
And, in the spirit of the Olympics, the first "winner" gets a gold colored looking smiley.
(sorry, no silver or bronze...)

Note: These pics were taken indoors, but near a large sliding glass door with plenty of light. However, it's not quite as much light shining thru the view tube as would be outdoors.
ETA: See post #29 for another series of pics comparing sun -vs- shade -vs- inside.
