Hello Grant,
Just taken photos to my own pleasure, never had any actual courses or training, just figuring things out by myself.
These photos were taken with Nikon D3100, about 1,2 metres distance with 70-200 objective at max andmanual focus, ISO 800 and shutter at f/5.6.
Light is from 40W regular lightbulb approximately 90 degrees angle from the camera at same distance with the blade and maybe 40 degree angle towards the blade. Background is black satin cloth to absorb some of the light. I focused the objective to a such angle that it didnt get too much glare from the light.
Like you said, now in the process of testing different angles of light and also combining regular 40w bulb and led-light etc. so probably have to figure a way to get the lights fixed to a stable mounting that is easily rotated and elevated etc.
Also have to try 300x objective as soon as I can manage setting up the distance to the target, my missus doesn't really like me invading the living room with all the blades and camera stuff. Women, go figure.
