Hello,

I need to write about an experiment in which an object
is photographed nine times. Three different lenses
are used, andthrough each of them three photos
are taken. 3*3=9. So far, so good.

But I want to be more concise and say something like this:

The object was photographed three times with each
of the three different lenses.

I had already written just that when it dawned on me
that this sentence could be understood to mean ONE
picture taken through lens A, one through B etc,
producing a total of just 3*1=3 photos. And this is not
what I am trying to say.

Am I right to worry? Or is my sentence not so ambiguous
after all?

Thanks in advance for any enlightment,
Leszek.
