graduation

now there's no doubt what these "gravures" could be.

One way of testing a camera is to point it at something with lots of very fine details and see how well the camera can reproduce them. Like trying to take a picture of "une gravure" = an etching made by an artist.

With your additional context it's clear that "une graduation" and "les gravures" are about s.t. entirely else: markings on the "iris ring" of the objective of a video camera, showing possible settings for the opening of the iris.

Just an idea: if your text is about a video camera, try to find an instruction manual for a professional video camera made in an English speaking country. (only "pro" video cameras have an iris ring, and you want to avoid Chinglish)

Yes, it is someone demonstrating a camera and making comments about the functions and features etc. The text in French is the text I need to translate.

which parts are a VERBATIM quote of the original text, and which parts are your comments.

"Donc c'est une graduation sur l'iris,
c'est une gravure.
Je saute de gravure en gravure"

is all of this a quote from the ST?

When you say (Text about a video camera) does that mean that your text is about s.o. testing a specific camera or model of camera?

"Je saute de gravure en gravure" sounds like someone testing a camera on different etchings, but it could also be a lot of other things. Not to mention that you would expect the testing of a video camera to be done on s.t. less static than "une gravure" ...

Definitely a bigger sample of the ST is needed.

It's impossible to tell without more context!
This could be totally literal: the graduations engraved around the aperture ring on the lens; BUT it is also possibly this is some kind of figurative allusion, which we cannot guess at without seeing a lot more of the woder context.
