Long term storage of wedding photos can easily turn yellow because the chemical substance imaged in the photos is mainly silver bromide, which is easily oxidized. Bromine is reddish brown and reacts with oxygen to cause the wedding photos to turn yellow. If you want to remove the yellowed part of the photo, you can use methods such as alcohol wiping, polishing, photo detergent cleaning, or reprint.
1、 What should I do if my wedding photos turn yellow
1. Alcohol wiping
If there is only a small amount of oxidation, you can prepare a few cotton swabs and alcohol, dip them in a little alcohol, and gently wipe the yellowed area of the wedding photo to remove the yellow dirt.
2. Polishing treatment
Polishing needs to be done in a large photo studio. Polishing refers to removing areas of the photo that are too bright, making the overall photo appear darker. This can make the yellowed parts less noticeable, mainly for leather wedding photos. However, polishing treatment can cause significant damage to the photo and should be carefully considered.
3. Photo detergent
Yellow wedding photos can be soaked in developing solution (exposure development) and fixing solution (fixing the developed image, removing non photosensitive silver halide), and then washed with water. The washing time can be extended to 1-2 hours. Please note that these two liquids should not come into direct contact with the skin.
4. Reprint
If there is electronic film, the wedding photos can be reprocessed; If there is no electronic archive, the yellowed wedding photos can be scanned into the computer, optimized and adjusted before printing.
2、 How to prevent wedding photos from turning yellow
1. Avoid moisture
Seal the photos with plastic wrap as soon as possible, or place them in photo albums, frames, or glass paper bags to ensure that the photos are dry.
2. Avoid exposure to light
Photos exposed to light will accelerate oxidation and must be stored in a cool and shady place.
3. Don't stack them
When placing photos, do not stack them together. Over time, the photos are prone to sticking together, and when torn apart, they may rub against other colors.
4. Touch less with your hands
There are often oil stains, bacteria, etc. on hands, and touching photos frequently is not conducive to their preservation. It is best to clip them in a photo album or wear disposable gloves to look through them.
5. Do not write with a ballpoint pen
Do not write with a ballpoint pen on the back of the photo, as it may scratch the photo. Try to write with a pencil or pen.
