For extremely poor persons who has not any enlarging house in Aberdeen :-)
a bit more about my earlier suggestion, the historical solution:
The sun(-shine or handy) enlarger (perhaps someone dont know...)
To make it with "modern" lenses (high F-stops) would be useful for
larger ratio of enlarge...
Below some ASCII graphic (visible by courier character type) to
show how working the sun-enlarger.

Advertisement: simple, cheap, anybody can make a tool like this,
without condensor lens and some other superfluous "UV filter",
you can control the result while exposition running, energy saving,
environment protecting, don't need to work in the stinky darkroom
but in the nature... etc.
(The voice of enemy: working only shiny days, need hours - days, weeks -
of exposition of each picture, any user seems like a stupid when working
with... etc, etc.)
