Various levels of a turbid suspension were introduced into a specially constructed tank and photographs of a variable transmittance sinusoidal object containing a step tablet were taken. The resulting images were processed and measured on a micro-densitometer to obtain the modulation transfer functions of the system. Results indicate that with increasing turbidity there is a speed loss, increased flare or reduced contrast, and decreasing modulation transfer functions. The increasing flare is not the only factor causing the demodulation of the underwater images.
