[Shades of Gray]

To clarify: Ammonia products are NOT recommended for ANY dyed films. The ammonia will cause the dye to result in a smeared/hazy appearance. It basically looks like it's eating away at the film. If you're absolutely unsure of what film you have...don't use ammonia products. Even some ceramic and carbon films will also come with disclaimers towards ammonia usage...due to being somewhat of a hybrid film, partially metallic, partially dyed...whatever the case may be. If this is the case...don't use ammonia products. Most top brands on the market today, their metallic series films will generally be ammonia safe. If it doesn't clarify...than don't use ammonia products. For example, the film we use will NOT be affected by ammonia. Therefore, again not to comparing one shop to another...film brands will vary from what you can or cannot use.
