This is actually technical metadata and the better approach (if you were
using METS) is to put it in a METS techMD section and linked to the
appropriate part of your structmap, but I don't suppose you're doing METS
at the moment. In fact, MIX, the XML schema for the NISO standard for
technical metadata for digital still images, indeed has exactly this
element: <cameraCaptureSettings>.

But assuming you are only creating a descriptive record in MODS, there are
a few options. One is using a note in physical description:

<physicalDescription><note>Camera settings: 100 f 4.5 TL
</note></physicalDescription>

The note does have a displayLabel if you prefer the following:
<physicalDescription><note displayLabel="Camera settings">100 f 4.5 TL
</note></physicalDescription>
although one usually would expect the note to be free text anyhow.

Another alternative might be to use the <extension> element, where you can
use elements from another schema. Using that you could point to the
namespace for MIX and then use the MIX element.  Here is what it would
like like:

<extension><CameraCaptureSettings xmls:
"http://www.loc.gov/standards/mix/mix.xsd">
then you would parse the data into its appropriate subelements as detailed
in MIX. (see: http://www.loc.gov/standards/mix/mix.xsd or the example at:
http://www.loc.gov/standards/mix/instances/mix_test.xml)

Another alternative if you are just using this locally is to use the
<extension> element with your own local element, e.g.
<extension><cameraSettings>100 f 4.5 TL</cameraSettings>

The intent of extension is to either use a local element or bring in one
from another namespace. If the latter, including the namespace allows it
to validate against that other schema. If you just use a local element, it
doesn't validate the data under it.

If you need further help with using the MIX element, let me know and we
can help.
