Radiographic TechniqueCâu 40 / 100
A radiograph appears too light and washed out even though the exposure settings were verified as correct. Which processing problem should be checked first?
a.Developer temperature that is too high
b.Developer solution that is too cold, too weak, or developing time that was too short
c.Excessive fixing time
d.Safelight bulb wattage that is too low
Giải thích
A light image with correct exposure settings usually means underdevelopment from cold, exhausted, or diluted developer, or from pulling the film too early. A developer that is too hot would produce a dark image instead. Excessive fixing gradually bleaches the image but is a much less common cause, and a low-wattage safelight makes the darkroom dimmer without lightening the image.
