Green Fireworks Effect
best filter for B&W portrait photography?
what's the best filter to use for black and white candid portrait photography?
something that brings out subtle skin tones (as much as you can in B&W) and delivers light soft-ish photos? i've heard of some that do this, but they cover up things like freckles (i don't want to do that)?
i was thinking of a red filter that would be very 'contrasty', but is it too harsh? i was thinking a blue filter might be too dark, but would it be best to get contrast of skin tones ect.? maybe something more subtle like a green filter? or none? i have no idea...
thanks.
btw, i COULD use post processing to re-create filter effects, but i would prefer to just use a filter. i can't stand photoshop, so i use macromedia fireworks. obviously i would have to do some post photo processing, but i would like to do as little of it as i can.
Light blue is good for young blond people. It really makes blue eyes pop in b&w but can increase blemishes. The yellow #8 is popular too.
A light orange is probably best for B&W portraiture. It's been a while but I think it is a #16 Filter.
I would shop around for a fully stocked B&W filter kit on eBay and just experiment since you are likely using digital. I've see the kits sell for less than $20 depending on diameter.

Wisconsin's Introduction To Fireworks
When browsing at your Wisconsin fireworks store or fireworks tents, a traditional item to buy for the 4th of July fireworks celebration is the firecracker. A majority of people do not realize how these items came into actuality. It is very interesting to ask Wisconsin residents "where did the existence of firecrackers come from?". The response is normally "I do not know."
It all started in China with tubes of bamboo shoots that were burned with fire, causing the air trapped inside to heat up with the sap of the green bamboo. Bamboo plants are ideal since it grows so quickly that pockets of sap and air get confined inside the plant segments. As they caught fire, the bamboos split and burst with a vulgar popping sound (known as "gung pow"). In early China, around 200 B.C., individuals used "firecrackers" to scare away animals from communities for protection.
Afterward, firecrackers were utilized to ward off bad spirits thought to be eating the husks of local rice crops. After years of doing this, the rice crops were deteriorating as villagers kept exploding additional firecrackers to the point that the town had no more rice to harvest. The Chinese God of Good delivered a message to the village that the firecracker explosions had been scaring away the Spirits of Good Fortune.
One more story behind the first practice of using firecrackers, was about the evil Chinese spirit called Nian, appearing on the eve of the Lunar New Year. It was believed that the firecracker explosion made the evil Nian disappear and made sure the people of a prosperous new year. As of today, scaring away this spirit continues to initiate fireworks celebrations in China.
The Chinese discovery of gunpowder centuries later provided more control of the bamboo popping when packed with the gunpowder. During the Han dynasty, study was being performed to find medicine that would allow Chinese people to live forever. Alchemists blended various combinations of sulfur, saltpeter and charcoal during the exploration and discovered when it was lit, an explosion occurred. This innovation resulted in burned faces and hands; houses even burned down. This material was later named "Hou Yao" or flaming medicine.
Most historians approve that the very first exploding mixture was inadvertently discovered by Chinese alchemists, the precursor to gunpowder appeared between 600-900 A.D. Regardless of warnings, many alchemists were amazed by the combination and continued experiments with it attempting to find ways to make it more powerful. According to the "Origins of Things" from the Song Dynasty of 960-1279 A.D., Ma Jun of the Three Kingdoms era of Chinese history initially used gunpowder in dried bamboo approximately 1,700 years ago. The huo yao, or gunpowder, when placed inside bamboo tubes and thrown in fire, blasted apart with a more commanding and louder bang than was created by the empty green bamboo.
In time, the Chinese revealed that concoctions of sulfur, carbon and potassium nitrate created an even more remarkable explosive. During war time, the Chinese used this discovery to propel hand-made missiles, and during peace time, it was an advancement for the traditional burning of green bamboo. During the ages, the firecracker holds its ancient title of "burst bamboo" (pao chuk ).
Airborne fragments of bamboo became a health problem. After 1100 A.D., the Chinese started packing black powder into firecrackers using twisted paper tubes and discovered the gases produced by the burning black powder would blow the tube apart with much more force and resulted in a larger blast. Until the late part of the 20th century, all Chinese firecrackers contained a straight 75-15-10 mixture of black gun powder.
Fireworks buyers in Wisconsin can thank this period of time for developing the idea of using these paper tubes.
As chemistry and competition developed, modern Chinese firecracker makers started using other explosive formulas by mixing powdered aluminum to initiate a flash effect, and called these "flash crackers". The title "black cat" has been a symbol of good fortune and luck in China, and brought about the most highly respected trading company called Black Cat Fireworks, the eldest and most familiar fireworks brand in the world.
