overriding automated flash photography mode

Hello Chieh,
thanks for your URL to I enjoyed some of the material there.

Maybe you can help me with your wide knowledge. I have two cameras where I would like to find a way to hack them so that I can get more control over my exposure. One is an Olympus D-600L digital camera and the other is a Minox 35ML silver-halide film camera.

Both have a level of automation in flash photography mode that the shutter closes very quickly after the flash illumination has ended. I assume the flash is stopped electronically as in all "automatic" flashes today, and I would also assume that the shutter is fixed to a standard "flash" speed such as 1/60 or 1/125 or something.

I would like to keep the shutter open longer after the flash has stopped. For example, with my fully manual OM-1n, I often use speeds of 1 sec with the flash. This allows the background ambient light to warm up my scenes and add more depth to the photos.

Would you know anywhere that I might find circuit diagrams or processor code or whatever that I may be able to doctor up a bit to achieve what I am looking for? That would be very cool.
