Carrier Type includes Media Type as a constituent attribute, which means Carrier Type "volume" includes "unmediated" and would therefore exclude "stereographic" for the intermediation attribute. One can't combine "volume" and "stereographic," and "stereographic" by itself would at least point to Carrier Type "other".
The stereographic carriers include "stereograph card," "stereograph disc," and "other." http://www.loc.gov/standards/valuelist/rdacarrier.html Carrier Type "other" would have to be used with media type "stereographic" for carriers that are different from the two defined ones: Stereograph card - mapped to 007 (non-projected graphic) /01 = h for "photoprint ... (opaque stereographs are included here)" http://www.loc.gov/marc/bibliographic/bd007k.html Stereograph disc - mapped to 007 (projected graphic) /01 = s for "slide ... Includes modern stereographs, e.g. Viewmaster reels" http://www.loc.gov/marc/bibliographic/bd007g.html For recording extent, RDA 3.4.4.3 instructions for multiple images in a single carrier might be appropriate - basically resulting in something in the form of "25 stereograph images in 1 volume", along with using Carrier type = "other" and Media type = "stereographic".

But I'm assuming that you also have text in this resource, so perhaps the logic might be that as long as you record *a* carrier type you are covered. So, I would say to myself "what I have here are still images (Content) that can be accessed using a stereographic viewer (Media) or can be viewed unmediated (Media)-although not the way they were intended, although you can apparently force your eyes to see stereographically without a viewer-in a volume (Carrier)", so: Content Type (336$a): still image Content Type (336$a): text Media Type (337$a): stereographic Media Type (337$a): unmediated Carrier Type (338$a): volume Extent (300$a): [n] pages Nature of the Content(500$a): Stereographic images with commentary text So, let me ask Greta's question again: is it ok to list a Media Type, without also listing its specifically corresponding Carrier Type, as long as you *do* list a carrier type for other contents?
