Fastest RC paper

[BetterSense]

I'm wondering, for the purposes of shooting in-camera, what's the fastest RC paper available?

Any preflashed paper will probably be the fastest and may get you up to ISO 10 or so.

I have not tried it out for the purpose you asked for but Kentmere RC is faster than most VC papers.
A thing to think about is regular B&W film will "see" all colors of light. B&W paper will not. You will get a different look depending on the paper you use. It will be like using B&W film with colored filters. VC papers are sensitive to UV, Violet, Blue and Green. Graded papers to "see" less green. A paper that is OK to use with an OC safelight of will not be able to see red, brown or orange light. A paper that says red safelight only! will see more colors than an "OC" safelight paper and will give a different look when used as a negative.

Ilford Express is perty darn fast. If memory serves, in normal daylight I've made exposures at around 1/25th of a second. I would have to dig into my notes to find exact data.

Edit: I reviewed some posts I made earlier on another website . . .

For a lens exposure: 1/25th of a second at f/8, 4x5 camera.
For a pinhole exposure : ~.5mm diameter pinhole, focal length of 165mm, exposure was 1 minute and 45 seconds.
