Jack Lindenberg, a professional photographer, propose a simple trick to see how long before you've used the movies you have in your hands. Just smell them !!!!!
In the era of electronic cameras and Photoshop, professionals of this kind still insist on analog-chemical photographic films, which, in their opinion, attributes points much better than digital ones. Of course, every technology has been in favor and against, but it is not our issue here. The article refers to those who still use chemical films and want to know before how long they have taken pictures of them.
As Lindenberg says, some time later he returned to his home after an excursion and tried to arrange roll-ups in chronological order but found that he had forgotten to mark them on the date they were exposed to the light. And then he did something simple. She began to smell them. He realized that the smell of film disappears slowly.
If the film smells intense chemicals, then it is freshly exposed to light. If the movie does not smell anything, then it's the first movie you've ever used.
When the film is exposed to light, the chemical scent begins to weaken, so your recent roll will smell more intense. Of course, this trick is working in rolls that have recently been exposed to light, since after a while, no one smells anymore.
