A weld shot using 9” rods to establish proper focus
distance. The rods were placed across the weld, but lining
them up with the weld is probably better to ensure that the
weld is always in focus. 1/150 second, 150 watts, 6.5 mm
lens, f=1.4
A weld shot, this time with the rods aligned with the weld.
The pitting (small black dots) of the metal is clearly visible.
Two 75 watt lights were used (same settings as last shot).
Light pointing could use some improvement to prevent
shadows. Also, a red / infrared cut-off filter may be useful
at this close distance (9”) to improve color definition.
A close-up shot of an anode. The lights close to the
camera caused excessive glare. Move them to the side.
Exposure 1/150 second, 150 watts light, 9” stand-off rods.
A picture of fish using ambient light exposure at 1/50
second exposure f=1.4.
