picture of IC Chips or Circuit Boards
Hi,
I am trying to take some closeup pictures of Computer Printed Circuit Boards with the letters on the chips showing, I need it to catalog PCB's with what chip or manufacturer id or part#. I have used a SONY DSC F717 in "M"acro? "P"ortrait and the Flower Icon, but unfortunately the out come is either too dark when flash not used or washed out when flash is used. I am using the inbuid pop-up flash. Also I tried using with extra flurocent lighting, but not getting the result I expected. Also I tried a +10 Macro lens but no good. I see so many people using this SONY F717 to take macro picture, but no one has described how they set their camera to do that or what lighting they have used. Appreciate if someone can point me to instructions that are useful to take macro picutres. Thank you Ohm |

Thank you Ohm Strong side lighting, try taking the project into the sun, as directly lighter as you can arrange without casting shadows on the parts. If that works, then you can set up with some artificial lights, incandescent probably the easiest to correct for color. flash is difficult because you can't see what's going to happen until after it does. A flash with tent lighting should work, but a bunch of incandescent bulbs would be easier to set up for low production. |

If I were to do this, this is my proposed setup.
Tripod for camera. Small easle, this to setup the module on. Desktop halogen lamp, this to illuminate the subject from the side, maybe 10 or 15 watts max. Adjust physical light position so that you can see the lettering in the view finder. You could try an LED flashlight as well. You could purchase a ring flash that goes around the outside of the lens, but this may be too expensive. http://www.cs.mtu.edu/~shene/DigiCam...RING/RING.html "Ohm" wrote in message oups.com...

It works very well, & is much easier than using a camera. -- W . | ,. w , "Some people are alive only because \|/ \|/ it is illegal to kill them."
