What is color rendering?

COLOR RENDERING

Color rendering relates to the way objects appear under a given light source. The measure is called the "color rendering index", or CRI. A low CRI indicates than objects may appear unnatural under the source, while a light with a high CRI rating will allow an object's colors to appear more natural. For lights with a "warm" color temperature the reference point is an incandescent light. For lights with a cool color temperature the reference is sunlight. The table below lists typical color rendering index ratings for a variety of lights, including compact fluorescent light (CFL) bulbs.

Lights with CRIs of 80 or higher are generally considered to have a high CRI. CRI values should only be compared when the light sources being compared have similar color temperature ratings.

How did john Dalton get eye disease?

John Dalton did not "get eye disease". He had, from birth, a vision abnormality that led to partial colour blindness -- red-green blindness. When, at the end of the 18th century, he recognised this deficiency, and wrote a scholarly paper which first described this problem, colour blindness became widely known as "daltonism".

Köpekler ne renk görür?

Soru eğer köpekler Colorblind vardır, özellikle kırmızı-yeşil Colorblind veya köpekler sadece gri tonları görmek köpek sahipleri arasında oldukça sık yükseltilir. Soru köpek vizyonu ile ilgili internet bile tartışmalı tartışıldı. Ama ben sizinle paylaşacağımız bazı bilimsel kaynaklar tarafından desteklenen istedikleri bu sorunun basit bir cevabı.

Aslında ben, sormak ve cevap ilgili bundan koymak istedikleri iki ayrı soru vardır:

1.Can köpekler renkleri görüyor musun? - Cevap: Evet

2.Are köpekler Colorblind? - Cevap: Evet

Beni ayrıntılı olarak size bu iki cevaplar biraz daha açıklayayım.

Köpekler renkleri görebilirsiniz

Köpekler sadece gri değil, aynı zamanda ne çok insan kanının aksine farklı renklerini görebilirsiniz tonlarında göremiyor. Yüz yıl önce bazı bilimsel testler köpeklerin renk görme ile ilgili daha fazla bilgi için yapılmıştır. Gibi düşünce ve araştırmacılar sadece renk görme bir köpeğin günlük yaşamın bir parçası çalmıyor sonucuna Ancak bu testler, bilimsel değildi.

Sadece 90 yıl sonra farklı bir köpek renkleri algılayamaz araştırmalar göstermiştir. Neitz, Geist ve Jacobs 1989 yılında yerli köpeklerin renk görme araştırılmış ve aşağıdaki bilgileri bulundu:

1.Dogs ve bu nedenle dichromats vardır onların gözünde iki farklı renk reseptörleri vardır.

Mavi-mor mesafeden 2.One renk reseptör pik, sarı-yeşil mesafeden başka.

3.Conclusion: Köpekler yeşil-kör olan kırmızı-yeşil renk körlüğü bir form da deuteranopia denir.

Bu sonuçları daha sonra Jacobs 1993 ile Miller ve Murphy ve meslektaşları ile 1995 yılında araştırma desteği vardı.

Dogs Colorblind vardır

Bu doğrudan ikinci soru köpeklerin renk körlüğü ile ilgili ulaşabilirsiniz. Colorblind herhangi bir renk göremiyor alakalı değil aslında sizinle aynı renk yelpazesi göremiyorum açıklanır Normal vizyonu olan biri. Çünkü bu renk görme eksikliği her türlü renk körlüğü denir. Bu nedenle köpekler onların iki renkli renk görme nedeniyle Colorblind vardır.

Renkler köpekleri ayırt edemez

Aslında renk spektrumu ışık dalga boylarında oluşan hepimiz için aynıdır. Bu renkleri sadece algı oldukça farklı olabilir. Gibi köpekler sadece belirli renkleri ayırt sorun gözlerini iki farklı renk reseptörleri vardır:

• Kırmızı - Turuncu - Yeşil

• Greenish Mavi - Gri

Mor • Farklı tonları

Listesi ve tamamlanmış değil orada eğer Colorblind hangi farklı olamaz farklı tonlarını bir yeri vardır. Ve sonuç köpekler renkleri görebilirsiniz ama aynı zamanda Colorblind vasıl olmasıdır.

What are the chances of a male with normal vision and a color-blind female having a color blind son?

Color blindness is an X-linked trait. That means it is carried in the X chromosome, which differentiates whether a baby will be a girl or a boy. Women have two X chromosomes (XX), and men have an XY combination. If a woman is a carrier for color blindness, only one of her chromosomes will be affected (we'll call it a little "x"), and for that reason she will not be colorblind. Men, on the other hand, only have one X chromosome, so any time they carry the colorblindness gene, they will be colorblind. A woman will carry the colorblindness gene if:

a. Her father is colorblind

b. Her offpsring are colorblind

She may carry the colorblindness gene if:

a. Male family members (brothers, uncles, etc.) are colorblind

A child inherits one chromosome from each parent. He/She will get an X chromosome from his/her mother, and an X from her father (if a girl) or a Y from his father (if a boy)

So, If a woman has normal vision (assuming she does not have a family history of colorblindness), XX, and a man is colorblind, xY, they have several different chances for different offspring:

Xx (a normal girl who carries the colorblindness gene)

XY (a normal boy)

Xx (a normal girl who carries the colorblindness gene)

XY (a normal boy)

The short answer is that ALL CHILDREN WILL HAVE NORMAL VISION. However, all daughters will be CARRIERS, meaning they can pass colorblindness on to their children.
