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

Great
Size: Medium, Number of Items: 1
I need something that was soft for my three year old and this ball is super great, it not only is the right size but it also fits in his mouth just right. Although he is a super aggressive chewer, the ball toy hasn't been totally destroyed yet and it is easy on his gums. The ball is so durable that got two of these toys just for fun.

The best!
UPDATE: 08/05/2025 - This is still one of my dog's 2 fav training/play toys. A couple of notes: 1. This is not a chew toy. If your pup is chewing up the rope, that's on you. That being said, you can get 100' of the poly cord rope at Home Depot for like $4.98. You can make nearly 100 ropes out of 100'. How hard is it to replace the rope????? 2. My pup is a now 15 month old Malinois. His original balls, purchase in September 2024 are still in everyday, multiple times per day, play. I did get careless and leave one where he got it and chew the rope. Easily replaced. Nothing to fret over. Yes, that was on me! 3.The foam ball is virtually indestructible! Replace the rope! 4. I noticed the price for the yellow large went from $12 each to $24. THIS will cause me to go elsewhere if they doubled in price. I LOVE these balls but not that much. I noticed they have a new yellow ball that has a strap vs. a rope. I might try that if I need one, but I have 6 of these balls, 2 never used yet, 2 that are virtually new looking, and 2 that have been in play since september 2024. I don't think I'll be buying more any time soon, but if I do need more, I hope they haven't gone up to $24 each. One of my top, go-to training tools. Quality is great other than the shrink wrap around the string joint. It's junk but not essential. Great tug and fetch toy. Essential to teaching a good "out" command (2 are recommended for this).

Best dog ball
This is our go to dog toy for our German shepherd. its great for training in sports as well as outings at the beach, considering it floats! Never had him destroy one, so its extremely durable. I like that its a bright color so its easier to locate when i accidently let go of the rope too late and end up whipping it 20 ft into the woods. Easy to clean, all around just a great toy. Also love the large size as having a dog accidently lodge a ball into its throat is a real fear of mine, I do not have to worry about that with this toy. I should also mention the rope is a must, as touching a slobbery ball isn't the greatest feeling in the world and it puts your hands out of harms way. I will forever order these.
