One technique for revealing hard to see silver marks or hard to tell silver repairs.

For the following the foundation is science but in practice it is more art so there is much trial & error and experience required to get good and consistent results.

When photographing a highly reflective metal objects many a photographer has mastered the technique of cooling/refrigerating the object first. Once cooled, the object is placed before the camera in a humid environment. The humidity condenses evenly on the silver object reducing the unwanted reflections.

The cooling/condensation technique can also be used to reveal other hidden things in the metal object. For example, a repair may be of different thickness or material composition and as such the condensation could be thicker or evaporate at a different rate than surrounding areas thereby revealing a well done repair.

The condensation/evaporation on the metal of marks that have been poorly struck or that have been over polished will often be noticeable because the marked metal has sightly different properties from the surrounding metal such that it will affect how the humidity condenses/evaporates.

Again let me stress the above will take a fair amount of trial & error and practice.

I do the "fog test" as I've named it to inspect silver for repairs, etc. I've never photographed a fogged up item, but I've seen some of the big silver galleries use that technique in their ads.

This post will forever change the way I look at pictures of silver. I have noticed pictures that appear to have been coated with a matte finish and was curious as to the methodology. Never thought about the condensation technique but will give this a try.

If you look closely, sometimes you'll see where it's evaporating and the normal shine starts to reappear. I've seen it on some of the pictured ads in the past.

Thanks so much for this, Scott. It's obvious in retrospect, but I wouldn't have thought of it in a million years.

In the 70's, London photographers to the trade, I was told, would mist the silver using a sprayer filled with milk.
