| Abstract: | The determination of exposure factor is the important technique in the aerophotography. The luminance model of sea bottom scenery is deduced in terms of characteristics of penetrating water aerophotography. The method of computing exposure time with luminance of sea bottom scenery is presented on the basis of analysing the exposure factor.The method is effective through the experiments. |
