...and marginally more seriously.....
I last tried out F22 for 30 seconds-ish at a time (assuming digital, otherwise starting thinking about reciprocity failure). Keep to low ASA figures - the marvellously low 200 for Cluddites
TBH you just have to experiment, but I'd start at small aperture and work my way bigger if necessary. The highlights are probably going to just blow anyway
