The Tiffen 5.65 x 5.65" Decamired Red 3 Warming Glass Filter - For those who want a�sure-fire way of�getting accurate color temperature readings, the decamired system is the way to go. Using this formula, you can transpose temperatures from one point to another easily and quickly. This system is also useful when you wish to bring a certain amount of creativity to color photography.

Applications include keeping color temperature constant during the course of the day and producing the effect of different times of day. Available in two series, reddish filters that warm the light and bluish filters that cool the light. Each series contains 4 densities: 1.5,�3, 6, and 12. Filters in the same series can be combined.

Decamired filters are designed to more easily handle unusual color temperature variations than the previously mentioned filters. Available in increments of both a red and a blue series, Decamired filters can be readily combined to create almost any required correction. In measuring the color temperature of the light source, and comparing it to that for which the film was designed, we can predict the required filtration fairly well.

A filter that produces a color temperature change of 100K at 3400K will produce a change of 1000K at 10,000K. This is because the filter relates to a visual scale of color. It will always produce the same visible difference. A color change of 100K at the higher temperature would hardly be noticed.

Calculations
To use this concept, subtract the mired value of the light source from that of the film. If the answer is positive, you need a reddish filter; if negative, use a bluish filter. Mired-coordinated filters are termed as decamireds. Mired value divided by ten yields decamireds. The 60 mired shifts, above, would be produced by an R6 filter, where the higher values were that of the lighting.

Sets of such filters generally come in values of 1.5, 3, 6, and 12 decamireds in both B (bluish) and R (reddish) colors. These numbers are additive; that is, a pair of R3's produces an R6. An R6 plus a B6 cancel each other out to produce a neutral gray.

The decamired system has an advantage over the Kelvin system in that the Kelvin scale is not linear
Decamired readings provide more accurate/controllable readings than Kelvin
The difference between the Mired value of the film and the Mired value of the light is the Mired value of the correction filter that correctly tailors the light to the film

A Simple Formula

  • Mired value = 1000000 : Kelvin value
  • Kelvin value = 1000000 : Mired value
  • For 5600K daylight color film, the Mired value is 1,000,000 divided by 5600 = 178.6
  • For 3000K artificial light, the Mired value is 1000000 divided by 3000 = 333.3
  • 78.6 Mired - 333.3 Mired = -54.7 Mired, or -5 Decamired
A positive value indicates a reddish KR filter, a negative value indicates a bluish KB filter
Thus, the filter required to adapt the 3000K halogen light (the slightly low value results from the mains voltage being lower than its nominal voltage) to a 5600K daylight color film is a blue Conversion Filter

ColorCore Technology

Tiffen filters are manufactured using ColorCore technology, a closely guarded proprietary process that entails permanently laminating the filter material in between two pieces of optical glass that are ground flat to tolerances of a ten-thousandth of an inch, then mounting them in precision metal rings
The ColorCore process allows Tiffen to control the color and density of their filters, and the characteristics of special effects filters with much greater accuracy than typical dyed-in-the-mass filters, which usually exhibit color and density variations

Superior Quality

Top Hollywood motion picture studios rely on Tiffen filters for their multimillion-dollar productions
Superior quality and design make Tiffen the overwhelming choice of moviemakers, professional photographers and even NASA
Tiffen has also been awarded an Emmy, from the Academy of Television Arts and Sciences, for its engineering excellence

Not indestructible, but pretty close!
Size: Yellow, Size: Yellow
I adopted a pit mix a little over a month ago, and so far he's managed to destroy every single toy he's had, including ones meant for aggressive chewers. He's a sucker for a good squeaky toy, and this had good reviews (and was affordable) so I decided to check it out. He's had his corn for a week now, and surprisingly, it's still holding up pretty well - though there are some caveats to that. My boy didn't even want to wait for me to take his corn out of the plastic bag, he too excited to get it. He went to town immediately, to the point where he was sitting in a puddle of his own drool after about an hour. He managed to squeak it (which I couldn't do myself), but still hasn't really gotten the hang of doing so - and the squeaker, when wet, does sound a little... Well, wet. He managed to have bite marks in it within the first six hours. Within a day, there were tiny bits of yellow rubber starting to appear anywhere that he played with this toy. A week later and there are some decent sized chunks missing from the corn - some of which I've had to cut off when they got loose and I worried about him choking on them. He loves his corn cob, and will likely get at least a few more weeks of play out of it before I have to toss it for his safety. I'm unsure of whether the squeaker is still functional, but he seems to love it whether or not it squeaks. Overall, it's not a bad toy for most aggressive chewers, but it will not last forever. The rubber is as heavy as the regular red Kong toys, but it feels slightly softer, which might contribute to his ability to break off little pieces. Make sure you keep an eye on your dog with this toy, or with any other, especially if they are chew goblins. But I'd definitely buy this toy again.

Solid piece
Size: Yellow
Border Collie loves it. Great for aggressive chewers. Prefers this to the carrot or the pineapple one. Probably better for large dogs than my medium size dog as there is some heft to it.

Probably indestructible since your dog won't want to play with it.
Size: Yellow
Boring yellow and rubber chew toy with a weird smell. My dog was not impressed.

Great chew toy!
Size: Blue
Great chew toy that dogs love! The toy is hard but also soft for comfortable chewing. The plastic is lightweight and does not leave sticky residue. It is super easy to clean so won’t leave the toy smelling like stinky dog!
