I would like to have more informations about those lights. Did they are good because the DEL light produce the perfect light to made a good picture? Is it more the flexible device too?
If I found a similar light with DEL, can I expect greats results too or the lamp on the jansjo light is better?
Thanks

What is "DEL?" Daylight Equivalent? Jansjos aren't in that color spectrum.
The Jansjos are favored because of their small size and infinite flexibility. Anything similar will be fine; the actual color temperature of the light is irrelevant.

Just taking a shot in the dark here - DEL = diode electro-luminescente (French)?

Sorry!! Your right LaureateBust! I forgot to translate DEL! I should use LED ! what do you mean by irrelevant?
Thanks!

I forgot this question in my last post. If I want to use light (at 10 and 2 O'clock) someone told me to use 5500 or 6500 Kelvin light. What kind of Watt should I uuse with those? Can we find the bulb at those Kelvin degrees with different Watt type?
Thanks again!

Any decent camera can correct for the color of the light. Any decent postprocessing software can do the same. It isn't going to seem an easy thing if you aren't computer- or photography-savvy, but I state plainly that it's extremely difficult to achieve good results with anything unless you devote the effort to learning the intricacies of the process.
It doesn't really get enough mention around here. Coin photography is an expertise, and you must take the root word literally. It's not automatic, not even close, nor even "easy." Your results will directly reflect the amount of learning you devote.
Only devoting that learning time will show how and why the actual color temperature of the light isn't relevant. Chances are your camera can correct for it, but if it can't, software can. Sure, you could spend hours and days of effort casting about for lighting which agrees with your camera, but that's taking your learning process down a dead end because it'll be the same thing all over again if you ever get a new camera.
Or, you can learn the same method of compensating for color that will apply to every camera ever made.
The problems with lighting are about getting enough light on to the coin, from the correct angle. That's it. "Enough" is fairly easy to achieve if you know how to manipulate ISO, aperture and exposure, but angles are problematic since they change for just about every coin. Hence, the most-adjustable lamp is always the most advantageous, and very little competes with the Jansjos in that regard.

I remember when I first got my D7000 and shot a coin photo with my 105VR lens. Spent a bunch of time getting the lighting just right, and the shot came out pretty nice. I posted it to another forum (thread-appropriate due to subject matter) and folks were impressed with the photo and asked what equipment I used. A couple guys came back and said something like "those results are to be expected with such high end equipment". The camera and lens together cost about $2500, and I now know that neither the camera nor the lens are optimum for coin photography! But most folks believe all that matters is how much you pay for the equipment and have no idea how tough it is, with any level of equipment, to get a good image of a coin...Ray

Extremely well said SSuperDDave. And, I agree with you 100% also Ray.

Expensive equipment makes the job easier, but there's a tradeoff: dSLR's aren't nearly as good a point-and-shoot camera as are true point-and-shoots. So, the knowledgebase required to extract good results from a dSLR can exceed that required of a P&S.
And it's not like an expensive, dedicated rig is required. I can think of a few members here who've demonstrated this clearly. DVCollector has both a P&S and a dSLR w/dedicated macro, and he achieves results with either which are indistinguishable in images posted here at CCF. A member who hasn't posted in quite some time, zacharycash, was using a Canon S5 IS superzoom with a cheap macro attachment and matching the quality of my best work with a dSLR & 100mm Macro costing 3 times as much.
Heck, some of the P&S's I've reviewed provided pretty decent results after a minimum of experimentation, but mind you I can only call it "minimal" having already learned the photographic/camera/lighting/postprocessing fundamentals I discussed above.
If your only goal is to provide full-face imaging for use here in the forum and as insurance backup, any number of instruments across a broad range of cost will fit the bill. It's only when you're wishing to provide sharp 100% crops of small details that higher-end, dedicated tools become imperative.
As Ray said, the equipment is only one slice of the pie.

I just bought a set of Jansjos to complement the set I got from Target. So far, the Jansjos are much better. They are way more adjustable than the ones from Target.

I use the Jansjo lights too--the like the flexible necks and easy of positioning the lighting angle. For brighter subjects like silver coins, I diffuse the light by covering the LED with tissue. It helps reduce highlights. Nice that others appreciate my shots--which are decidedly low-tech compared to their rigs and their professional-quality results.  |
