  13. Are you using a yellow speed easel?  This caused a 40cc yellow shift when
  14. I did my first cibachromes.  For color neg I guess an easel equally cyan
  15. and magenta would give a yellow cast.  I switched to an all black easel
  16. for ciba printing and two things happened, the color shift disappeared and
  17. the prints were sharper too as no light was reflecting off theeasel and
  18. re-exposing the emulsion.
