Rachelle, Are you exposing using the WINTER sun in Kamloops? It's not going to have much UV action. Try using an artificial UV source or wait for summer. alternativephotgraphy.com has lots of info on UV sources - including building your own.
I use a tanning bed, no joke! I got it for $50 from a client who inherieted it from Grandma and had no use for it. I've now got 3 contact printers so I can mass produce. it just seemed too silly to get all that light going for one little 4x5 print.
