These points come out often in the discussion of coin photography. Especially when using cheaper cameras trying to get good quality photo,s. I have been using my Canon point and shoot and have been getting decent results, yet not exactly what I'm looking for without going DSLR and expensive lenses....one thing I noted was lighting and its importance, yet it tends to over light and loose detail of the overall coins fine details if your trying to capture VAM's.
So I went back to the old 2004 Canon Power Shot Pro1 and used the techinques learned here on the forum...The first 2 pic's are with 2 desk lamps at say 10&2 o'clock..slightly pointed away from the coin as it tends to be over lighted and loses the fine detail..
note reverse coin is not in focus as the batteries were down so it wouldn't give me the green light, but the luster and color are there...

NOTE the above 2 have not been altered or sharpened just re-sized to get onto the forum..
The next 2 are with the old faithful milk jug..diffusion.

I had to try my luck with color correction as with the light captured within the jug does enhance details it also
throws the color off......again no sharpening, some color corrections to try and get close to the coin in hands appearance, but as you ca see from the first 2 photo's its still not right for color..
I am wondering...
one MUST have good lighting to really get the coin onto the sensor, yet too much yields poorer picture quality,,
Diffusion allows better stronger light (better F/# and shutter speeds) to enter the field but the colors wrong, is there a compromise? I'm sure the milk jug is handy but its not the right thing to use...any ideas? thanks...

It may be impossible to capture all important aspects of a coin in a single shot. I've been trying but so far no success. The four factors are Color, Luster, Design Details, and Surface Details, and they all require different lighting techniques. I posted a comparison of the techniques a while back, and showed that you can superimpose (using image averaging, or multiple exposure) different techniques to bring the factors together into a final, contrived image.

I recently read that article, not sure how one does that..eventually I will have to learn about it...the one thing I have noticed is the GLASS, I currently am using.. the newer point and shoot Canon power shot A3100 IS has more MP than the old pro1 12 VS 8,,,but after figuring out how to use it, I believe its far superior in quality than the newer camera....must be the lens...
