在总结化学减薄和强光校正曝光不足彩色反转片的基础上研究出一种更佳的校正方法 .它利用现有的暗房设备加之自制的一套组合配光镜 ,用物理配光的方法 ,对曝光不足相差二级以上光圈 ,冲洗出不能使用的彩色反转片进行校正 ,洗印出了一幅图像清晰、层次丰富、色彩还原好的彩色正片 . In the summary of chemical thinning and strong light correction underexposed color reversal film based on the study developed a better correction method which uses the existing darkroom equipment plus a homemade combination with a combination of light microscope, Method, a difference of more than two exposure to the aperture, rinse out of the color reversal film can not be used to correct, printed out a clear image, rich layers, color reproduction of a good color positive.
