The gray card I needed but also because how can one else on site, with difficult lighting conditions, if necessary, make a time exposure? Or, what is more likely that if you want to use JPEG, eg due to continuous shooting, or must, then, of course, want to make a manual camera white balance.
Immediately I had both white balance solutions used in parallel, the gray card set was spread quickly placed into the picture, the SpyderCube one had first of all pay attention to the correct alignment of the black case on the camera location and at about the same height to the camera, which he likes only when aligning then a couple of times, due to the overload and, for practical use, too small stand base, fell over.
Well, since there is still the rubber strap to attach, just hopefully find something and then he twists not yet in high winds. As appears below the line, in terms of use, so it is best to put the cube on a tripod, as illustrated in the instructions, only you are allowed to field either lugging tripods or two once you are engaged in unscrewing in the hope that you want to do not just eg macro photography.
Why has he in the more respected of money over gray cards, not on a possible practical and practical use? By itself, the idea of a "gray card" with better fine control options, not bad, just the implementation lets me then but take up my plastic card bundle.
Now for the results in the post: To make it short: Both solutions are equally good, you get a neat and proper white balance in RAW converter towards it. Just so has the Cube yet the nice additional features, such as the Black case, to provide the instructions for some really usable unique selling point compared with the gray card ... forget it, which one can in practice almost namely terminals! I knew that before longterm employment in terms of color management course but not yet.
The background is that yes, the grays, which could be so correct well, located just proportionally composed red, green and blue at different brightnesses of the three primary colors and higher quality cameras nowadays the neutral density is nearly linear, otherwise it will be major shifts in the colors would that then manifest themselves as color casts.
In short: You need really really just a simple gray card, even if, of course, has by additional reference colors with greater control for comparison, but at the latest with gray card, black and white reference should be the neutral density actually under control. In the documentation of the Spyder Cubes
One has since larger color problems after the white balance shifts, you should therefore prefer to grab the same to one of the cheaper profiling solutions such as the ColorChecker Passport. For a real profiling when you need absolutely 100% correct colors, the ColorChecker has too few fields, but as color correction solution for poor cameras he should, in my opinion, do more than good service.
Make the white balance using cheap paper such as handkerchiefs, is a bad idea. To make the paper subjectively "white", optical brighteners him be added namely that reflect a portion of the UV spectrum than blue light again. Due to the increased amount of blue it looks then a total "white" and to make the white balance if necessary on this light blue.
Saturated the advertised product description "silver bullet": "This is not just another gray card", there's still only an overpriced, supposedly advanced gray card, which is to use thanks to lack of exposure, etc. not even fully as such, but with can shine particularly inept handling.
