The background is that I've been trying out a Canon Powershot digital camera on a tripod with the Canon Zoombrowser software that lets the camera be controlled from a computer via the USB.
This works well but illuminating the subject (a ragbag of documents and old pictures) with desk lights using ordinary GLS lights gives a visible pulsing of light which can be seen in the monitor due to the
50Hz mains frequency. [which means 2 flashes per sec or 100Hz] This isn't ideal as it clashes with typical camera exposure speeds.SFAIUI professional copystand lighting is expensive, so looking for a method of obtaining a smoothed light.
One possibility would be DC lighting, but it needs to be quiite bright.
Another possibility might be flourescent lighting - but does phosphor coating on the tube provides some lighting persistance?
Any views on feasibility of either (& how to achieve it) or any other suggestions would be most appreciated.
TIA
