Which are true of making a test strip?
Hints
- Three concern how the strip is made and read; one claims it settles a question it cannot.
- A strip tells you about exposure, and grade is a separate control.
Show the answer
- A. Arithmetic steps of 5, 10, 15 and 20 seconds give uneven intervals in stops
- B. Geometric steps of 4, 8, 16 and 32 seconds are one stop apart
- C. The strip should be developed for the same full time as the final print
Why
The fourth is a category error. A test strip finds the exposure that puts the highlights where you want them; whether the shadows then fall where you want them is a contrast question, answered by the grade or the filtration. The two decisions interact and neither substitutes for the other.
