Do you want to know about led light? Here are some frequently asked questions.
1. LED light strips on cars/Laws?
ASk your local PD about lighting restrictions. There may be regulations related to the color that you use
2. Does an lcd tv have a led light bulb or a florescent light bulb? How long will a lcd tv last.?
LCD can have either LED or CCFL backlights. It varies from model to model. The only way to know for sure is to look up your TV's spec sheets online or consult the manual. However, being that yours is a 15" Magnavox, now pushing 3 years, I can tell you it is a CCFL. LED backlights are not used on such small sets, and definitely were not really out there in the norm (if really at all) 3 years ago. What does that mean for the life expectancy? Nothing really. All sets are rated differently. You need to track down the model number and then go online and see if you can find out how many hours your set is rated to. It simply being a CCFL LCD does not guarantee any number of hours, you need to actually look that up. Realistically though, I think 30,000 hours might be what you would be looking at with a set like that. Maybe 40,000 with a bit of luck. That translates into like 10-12 years at 8 hours a day 365 days a year. So at 3 years old, even if you've been abusing the hell out of it, I would expect you to at least get a couple of more years out if it, at the very least.
3. How to Choose the Best Light for Product and Food Photography
When it comes to lighting, choosing the best is important because it can make or break your photo. And nowhere is this especially true than in product and food photography. Taking good photos of products and food require you to highlight the merchandises' best features. In food photography, it is essential to come up with photos that entice viewers to try the food or visit the restaurant. This is why it is important to choose the best light/lighting source for your shoot. Aside from encouraging people to try out a place or a dish, food photography is also used to signify a particular intent or mood. It is also an effective stimulant for people who want to try a healthier diet or for those who want to lose weight and live better, longer. Most of all, taking photos of food is one way of keeping or treasuring the experience, which disappear as soon as you finish eating. Of course, it's also a way of documenting precious moments with loved ones and friends. Product photography is quite similar to food photography. You will know when your images conveyed the right message when people are curious and eventually buys or tests your product. But then again, to be effective, you will need the best or most ideal lighting source for your product or food photos. The Best Light Sources for Product and Food Photography Let's focus on three varieties of light sources: natural, flash or strobe, and LED light. Natural lighting is always the best option for product and food photography. First off, the food you are featuring looks more natural and therefore, more appetizing. So, as much as possible, look for a good source of natural light like a window or a ceiling opening. The bigger your light source is (such as a huge window), the better - more natural light will get in. There are several advantages when using natural light for your food photos, foremost of this is the one mentioned earlier: it gives a natural look to your images. Your photos appear as they are in real life, which means the colors are authentic and crisp. Another advantage of using natural light is the fact that it's free. You do not have to spend a single dollar for using it. But there are disadvantages, too. First off, natural light can be inconsistent and unpredictable. Why? Because it depends a lot on the sun. So if it is cloudy or rainy, you wo not have any natural light source to work with. It is also not reliable because the natural light source in the place you are shooting may not be enough - perhaps there are no windows in the area or you are shooting in a corner. The second disadvantage is you can not really shoot at night. This is one of the reasons why a lot of photographers use artificial light sources instead. The third disadvantage of using natural light is you cannot control or adjust it automatically. You always have to take note of weather conditions. Many photographers use diffusers and reflectors to get more light when shooting in natural light. Natural light is best used for product and food photography done in areas or places with strong and uninterrupted natural light source (i.e. good weather conditions or in the daytime). It is also recommended for photographers who like to bring out natural colors in images. Flash or strobe light produces high-powered flashes of light when used. The biggest advantage of this light source is convenience, because you can use it in the daytime but also at night. A flash or strobe light is also compact and portable, so you can easily bring it with you. Additionally, flash or strobe light can be adjusted according to your specifications. The flash of your camera can be used with a diffuser or you can turn it towards an all-white ceiling or wall. Likewise, you can use a reflector for softer effect, or adjust and turn down the flash's power to create the effect you want. Another advantage is that you can easily mimic the sun's light. All you need is a softbox big enough to simulate a window. You can also add gels, beauty dish, and an extra flash. But there are disadvantages, too, and the biggest one is the fact that you wo not be able to see what will happen to your image until after you take the shot. As such, you wo not know where the light will specifically fall, or if the light is too soft or too powerful - not until the shot is done. Although there are strobes that come with modeling lights that give you a preview into what the light will look like, these varieties can be quite expensive. Flash or strobe light is normally used when shooting at night, in the studio, or in any enclosed space or area where there is not enough natural light available. It is essential for a photographer to first master the camera flash before attempting to use it. Strobe lights can be a bit of a challenge for beginner photographers, but learning how to use them can be easy. Another variety of artificial light is the LED (light-emitting diode) light. It may be not as popular as flash or strobe, but it is slowly making its way. This light source is "directional", which means it emits light in a specific direction only and not in multiple areas. LED light used in product and food photography has a lot of advantages: LED light is cooler than other artificial light sources, so no matter where you are shooting, the surroundings wo not be engulfed in heat. LED light uses less energy than strobes, so it is efficient and environment-friendly. LED lights come in various colors and intensities; and since it has a lighting panel, you will be able to see your shot as you compose it, which means you will know what you need and do not need. The disadvantages of using LED light for product and food photography are as follows: The color/s may not come out the way you expect it to be. Aside from incoherent colors, LED light can also cast unwanted shadows. Using LED light for photography can take a lot of getting used to. It's not powerful as strobe or flash. You will need at least 300 LED light pieces (with approximately 5,000K) to achieve a typical flash output. And The Winner Is? So, should you go for natural light sources for product and food photography, or is artificial lighting better? The best option would be to go for artificial lights because it's very convenient, you have full control, and you will get a consistent output. My current setup is a high-powered flash (with high-speed sync) one 300-piece LED light two reflectors. But ultimately, it will depend on the shoot and its requirements. If natural light is good for your shoot, then use it. If natural light is absent or minimal, use artificial light sources. Or, feel free to combine natural and artificial lighting. It's really up to you, but I hope you know have more knowledge to help you decide after reading this article :)
