Ok i dont know if its me or just the way i've worded the question about the tester i want to make.
To make life easier the "timers" i want to use to display the shutter speeds and run time of the shutter are just like a stop watch you wouls use in the track and field events etc.
I want to have 5 on the screen. modern 35mm cameras have a top shutter speed of 8,000th of a second, but we only normally adjust and work on speed 1000th of a second and slower.
Can any one help with the "stop watch" or will the timer advise i was given on my last question do the job??
