Why should you convert slides to digital, you might ask? The truth is that you need to convert slides to digital now to stop the degradation of the image that occurs over time, and before it is too late. The conversion to digital images protects the media against the ravages of time and environment that is otherwise inevitable.
When the film was originally made of cellulose nitrate used as the basis on which minerals are sensitive to light were applied. Minerals sensitive to light were composed of silver salts. Most of the early films in black and white have been shot with this type of film. He did very well to capture images in black and white though, but it was a failure to retreat. Nitrate film was supported extremely flammable. As the negative was sitting in the vaults slowly dissolved in a highly explosive Goo. More studio had ripped the steel doors where nitrate film was exposed to an ignition source. On a day with lots of static electricity in the air, simply open the armored door could trigger an explosion with a tiny spark from metal rubbing on metal.
The next generation of film eliminated the problem of explosive nitrate film, but it does not eliminate the problem of image deterioration over time. Modern color film has a base of transparent acetate or polyester, which is applied emulsion is on. This emulsion is composed of three layers of color dyes containing bound by an emulsion-based gelatin. The three color pigments are magenta, yellow and cyan. These three layers are all it takes to produce real life like color. Unfortunately, these dyes are subjected to color decay over time if the film is not stored properly. Humidity and heat are the two main culprits in the slow loss of quality.
Another reason you need to convert slides to digital is the sweetness of the emulsion used in movies. Not only color film fade with time, but the emulsion is sensitive to scratches. Once you have a scratch on a blade of 35 mm, you're stuck with it until you convert to digital. There are many programs that help eliminate scratches, once the image is converted to digital, but it is best not to get the scratch for the first place.
The digital images allow you to create slideshows with transitions between slides and the music underneath that creates a presentation, professional entertaining. Once the slides have been digitized, you can also add titles, jumping, and apply color to accentuate move ins.
Among the many reasons why you should convert slides to digital, the most important is that by beginning the process of conversion, you are preserving your memories for you, your family and for future generations of parents to act now before it's too late.
