General Advice All exposure times are standard values. It might be necessary to adjust or modify the above indicate values, depending on the type and brand of the intensifying screen and the x-ray film. If the developed radiographs turned out too light, they are underexposed. If the developed radiographs turned out too dark, they are overexposed. If pictures are too light, increase sec.by one step. If pictures are too dark, decrease sec. by one step. Do not change kV value. Darkroom conditions can also influence quality of radiographs. Check chemicals and temperature of developer (hand tank 18-20° C – Automatic processor 30-32° C).
