​重倍酸鹽明膠對溫度和細菌反應敏感，也對環境的溫濕度敏感，恰潮圖，圖像不穩定，容易消像，且倍對人有毒，所以應放在密閉容器中保存。

酸鹽明校具有高射般事和高信比的優點，缺點是感光度低，只有（3-7）×103Jcmn2是柯達640的百萬分之一左右：

重倍酸鹽明膠對溫度和細菌反應敏感，也對環境的溫濕度敏感，恰潮圖，圖像不穩定，容易消像，且倍對人有毒，所以應放在密閉容器中保存。

用膠有硬化和未硬化兩種，來硬化的明膠可以製作浮雕型全息圖：硬化的明膠適合於製作折射型的位相型全息圖。由於這種材料被光照射的地方不變黑，

在全息圖再現時不吸收光，因此其銜射率高，用它製作的體積全息圖的衍射效率可達到90%。質鉻酸鹽明膠是應用最早的照相材料，明膠是從動物的天然蛋白質骨膠中提取的。

明膠中摻有少量用以敏化的重鉻酸鹽後，用短波長的藍紫光照射，曝光的地方變硬，較未曝光的地方難溶於水，水洗後可以形成厚度、密度或兩者兼有的變化，

因此可用它做全息材料，產生由厚度或折射率調制位相型全息圖。重鉻酸鹽明膠吸收區的波長大約為540m，因此只能用於氯離子激光的5145m和48m被長，

成氮鎘激光的412m波長。因為重鉻酸鹽明膠乾版，不像滷化銀乾版中有微小的銀粒子，所以它的解析度很高，可達20005000線/毫米，

如果用氨氖激光的628m波長，在明膠中還得加入其他敏化材料，常用的染料有亞甲藍和亞甲綠。
