In the last few weeks I have been taking a lot of variety shots (which require specialized lighting to get shadows right), testing lenses (I got a new toy...a Zeiss 74mm S-Planar), and comparing cameras (Canon XS vs T2i), and have been lazy about full coin lighting. So I decided to test go back to my "calibrated" Smile Director setup, and snapped a pic of the coin I was using for the camera comparisons. Here are shots of the coin with 3 lighting styles: two lightly diffused; one lightly diffused with reflector; and two Smiles with reflector. Let me know your preference.

For me it's the second shot. There are little to no hot spots.

I also like the second one for the same reason as dave700x, and it seems to show more detail. There seems to me to be a difference is color in all three. I wish I could have the coin in hand to compare.

The toning certainly comes through best in the third shot, and least in the first. I guess if that's a dominant feature of the coin as viewed in-hand, then you'd want to prioritize showing it. Overall though, the first one wins hands down for me. I value sharpness and detail in coin images, and the first one has both in spades. True, in the first image there are hotspots; to me the second and third make up for the lack of highlights with an increase in heavily shadowed lowlights. This gives them a bit of a muted appearance to me. I guess subjectively I'd rank them 1, 3, 2.

Is the workflow the same? The first shot almost looks like it was stacked and the second and third weren't.

Good eye! The first was indeed stacked, which accounts for the added sharpness and detail. In fact the second two were not post-downsize sharpened at all so don't look quite as sharp. I was more interested in the lighting comparison than other factors. First was taken with 75ARD1, while second and third were with 105PN. So while these shots are not fully apples to apples, the color presentation, luster, hotspotting, shadowing, etc can all be compared since the primary differences are in lighting. In other words, if I stacked with the 105PN I'd get about the same sharpness on the second and third shots as the first.

Preface: These three shots all have different strengths, and I'd be happy to achieve any of these results!

I would anticipate, without seeing the finished products, that if #3 where treated as #1 with regard to workflow, I would prefer that particular mix of contrast, lustre, toning and detail. But, #2 does present the lustre better than #3... I guess it depends to some degree on the coin!

Shows you what I know and can see at the very first. But after reading the next posts and looking again, I can understand and see what you're looking for.

Ray, I have been trying to think of this....
"reducing mode"...
per say.. as when we take a full MP pick and down size it..."LIKE ME"
and try to get it down to less than 100K..
I'm seeing our using Photo Bucket, so your pictures details are not getting lost in the clouds if we capture them and ZOOM in on them the picture doesn't disappear...So obviously my down sizing by 4 or 3 or 5,, does not get the favored mathematical reduction rate when I try to get to 100K for posting here...
...MY point is this,,,,Ray as done the math.....RESULTS...VUNDABAR...as seen on this site...
However...most of us not using these external sites which CCF allows to present itself full feature...DETAIL..
far beyond the 100K. which looses ? 16MP pick to 100k? lets do the math....CRAP for real detail...
SO should we not be using an out side source which will allow a much better picture to be shown on
CCF........Should we shoot with a lower MP rate>>>?
SO I don't loose so much when I post a pic?
\What would you recommend?

I definitely don't recommend shooting at a lower pixel depth. It's always best to shoot at max resolution and then downsize, even if the downsize is non-ideal. I don't know the ins and outs of adjusting the picture size to meet the 100k limit, as I've used Photobucket pretty much from the start of my web-posting. I'm not sure how much you're giving up fitting to 100k, but I am pretty sure it's something. Pesonally, I am not willing to compromise if I don't have to...

I don't care for the third, which is too flat to me, even if it shows off the color best. I'm torn between #1 and #2 (excluding the sharpness which is not attributed to just the changes in lighting.)

Considering any CCF member with 50 posts can have their own Gallery, hosted on our servers, which isn't subject to the 100kb limit....doesn't really seem necessary to force yourself into a corner.

I have no trouble getting a 1000px image at 300kb, and an 800px image just over 200kb. Those are small-enough for just about any connection, even dialup.

I like it - a lot. Now I'm curious, does one of these three lighting setups result in an image that you feel represents this coin satisfactorily?

The coin has luster, and it has color, and it has a few tick marks and small scratches. Holding it in-hand, the tendency is to use a single incandescent or halogen light and to tilt the coin a bit so the light shines off it, then to tilt it around until all the areas of the coin are visible. We do this because it's not possible to hold the coin in-hand and see all you want to see in a single view. What we ask for from photographs of a coin is simply impossible to duplicate in-hand, and if you snapped a single image of ANY in-hand look, you would be very unhappy with the result.

Now, I like the way you asked the question. Some folks say "nice image, but does it look like that in-hand?", and that question is a pet peeve of mine because, well, no it doesn't. What you asked was "does one of these three lighting setups result in an image that you feel represents this coin satisfactorily?", and answer to that question is yes. IMHO, the image #2 represents the coin best. The coin is both lustrous and colorful, and while image #3-1 and #3-2 show the color the best, they don't do justice to the luster. The lighting is just too high (nearly axial), and too diffused, and the double lights do too much to emphasize color at expense of luster.

I will re-take this coin once again, in a style more like #2, but with the high-resolution workflow, and will publish that result hopefully a bit later today. Maybe image #2-2 will be the definitive one for this coin? We'll see.
