This a good example of why you should avoid short developement times-
 the uneven edges as seen in this shot are certain to occur.
Most commercial labs have never been good at black and white 
negative development-color is much easier to control and maintain 
chemistry- for tech pan you need a compensating type of developer 
that loses energy in the higher exposed regions as the lower tones 
keep developing. Simply under developing in standard developer won't 
work. With all the limitations of tech pan besides development-you 
would be much better off shooting a standard slow speed film and 
processing at a lab that uses xtol as the solution.
