User:Hym3242

This user has great enthusiasm in the study of microforms (including microfilm, microfiche, and micro-opaques) and all stuff that relates to (or contributes to the understanding of) them, including but not limited to bullet points below. This user also holds a small collection of rare microform specimens and ephemera (including dozens of microfiches of microform equipment brochures in the 80s). If you have any questions about microforms just ping me. I may be too lazy to get up and contribute without someone giving me a little nudge and push! Sadly in this economy I hardly have the time and energy to contribute.

• bibliographic reference (for locating ALL materials relating to microforms)
  • reference work in general
  • librarianship in general
• microphotography (the technique of reducing patterns) (the field where i have extensive knowledge and have done many experiments trying to replicate ultrafiche tech)
  • photolithography
  • lithography as in graphic arts
  • holography
  • basic optics in general
  • microscopy (since microphotography involves microscope objectives used in reverse)
  • factors affecting film resolution (to which turbidity is often the limiting factor) and the formal description and simulation of them. This is well documented in photolithography.
    • originally designed test patterns for personal testing
    • film simulation with Mathematica, to know how (and why) microfilms look like when approaching resolution limit, having incorrect exposure, with low contrast target, out of focus, etc. Also training the eye to notice problems with real world specimens.
    • microdensitometers
• film identification and preservation
  • the diazo process, either on acetate or polyester
