I have the Holgaroid too! Really enjoyed the article and the tip on the Fp3000 film! If only fuji can produce a peelapart half way between the both it'd make life a lot easier!
I've also found the fp100 even on a very bright day to be underexposed still
Only method is the MX way which requires a tripod or ultra steady hands but I've been having fun with MX on different scenes and objects and combined with the ring flash!
