Q:I currently use a Nikon D5100 but am soon upgrading to the D600. I want to be able to use several speed lights. I know I will need a transmitter, but not sure what else and how they go together.

I agree with DeepBlue. I use a bunch of YN460's with some cheap radio triggers, You'll also want some lightstands and umbrella mounts. Example shots: flic.kr/p/9bWK3U flic.kr/p/8mggaa sphotos-b.ak.fbcdn /hphotos-ak... Basically, you'll put a receiver unit under the flash and put a transmitter unit on your camera. The transmitter will tell the flashes to fire when you press the shutter release. Remember not to set your shutter speed higher than your flash synch speed (usually around 1/200th max) or you'll end up with a large black band.

Q:3 days ago my check engine light came on, so I took it to a shop and had them scan for codes. Came up with the old loose gas cap code. The cap was neither loose nor old (I actually had just had it replaced a few months ago), but I replaced it anyways. The light stayed on, and the mechanic told me they‘re no longer allowed to reset the check engine light for that specific error code. New federal law, apparently. I thought that was pretty weird, but anyhow, the light went off this morning on my way to work. I don‘t know what this indicates, as I‘ve always had the system reset by the mechanic once it‘s fixed. Does it go off by itself over time if the problem has efficiently been fixed?

Nothing to worry about. What happens when a code is given and repaired with the emissions system is that the engine is required to operate for a specific number of drive cycles. This may mean a number of starts and stops and or a certain number of miles that must be traveled before the light will reset itself and the problem will have been solved. You can call the vehicle dealer and ask the parts department or service department how that works on your particular vehicle.

Q:I saw some photos from a Lumix digital camera taken in very low light (a bar). They were black and white, with almost an infrared feeling to them, and sharp (not that grainy).Can anyone tell me which model might be able to do that, or what the feature is that allows this on a point and shoot?Thanks.

in case you quite need stable low gentle photos, a DSLR is the thank you to pass. The D5000 is a stable selection. It this is too huge, you are able to evaluate the uber small Olympus E-430 with the 25mm pancake lens, which will in great condition conveniently on your jacket pocket. Pentax has a form this is slightly smaller (the K10D?) in case you prefer to restrict your self to a factor and shoot, there are countless available withe APS-C sized sensors. There slightly pricy, yet while the D5000 is offered you are able to have the potential to locate one. i'm attempting to bear in innovations specifics.the Sony R1 isn't any longer made, and that's as huge as an SLR. Samsung's NX isn't available yet. the Sigma DP1 is, in case you are able to take care of a fastened 41mm lens. If all that would not excite you, seem for a digital camera with FEWER megapixels. Fewer megapixels potential that the digital camera can ramp up the sensitivity of the sensor with much less noise, because of the fact the pixels are much less squished jointly. once you seem at digital camera specs, many times the bigger the sensor and the less the megapixels, the extra effectual for low gentle pictures. that's no longer continually authentic, counting on the digital camera's NR ability. in spite of the fact that that's stable place to start.

Q:The guys at auto zone said it was the gas cap. If this is true what needs to be done to make it go off?

Try removing it then placing it back into place firmly and see then if the light goes out after a bit of driving but it should go out right away if it was just a matter of the cap being slightly loose etc.Otherwise the cap's seal is gone and you need to replace the gas gap and if so you minus well by a locking gas gap bec they don't cost much maybe 10 to 20 bucks. Hope that helps and best of luck.By the way a loose gas cap causes pressure changes etc and that's why the engine light code error.

Q:Ok so I was driving and out of nowhere my engine light comes on and when I would complete a stop on a light my car would shake. It also kinda wanted to turn off on me but it didn‘t. And when I was in a stop and then accelerated my car would take out white smoke out of the exhaust. Also when I would try to accelerate it would have trouble accelerating it didn‘t want to go. And it kinda smell like gas also.I have a chevy cavalier 1999Please answer thank you

First best answer to StPaulGuy. Guessing will not get you any closer to fixing the problem, getting the codes read will. A mechanic should do it and he should be the one to fix it. Parts stores can cost you a lot with missing the mark on diagnosing based on the codes. I disagree about the head gasket - I have never heard of a head gasket failing out of nowhere (as you described it) and the symptoms are not a good match. For a sanity check, check the coolant level. If it is way, way down it could indeed be a major problem with the engine rather than the controls. If it is not missing a lot of coolant it is not a bad head gasket causing the problems, I guarantee.

Q:my oil light, brake light ,high beam light ,abs light,brake light, shift light,check engine light, are stuck on when i start the car they never go off ? any clues whats wrong?

Try disconnecting the batter for 30 secs and then reconnecting and starting the car. Your ECU may have locked during system start. Also take to your local auto parts store and have them run a diagnostic on the ECU to see if any there are any trouble codes.

Q:how do i reset my check engine soon light on a 2006 buick rendezvous, weve done the repairs just cant reset li?

sorry to say you need a code reader that has reset/erase code function . yes you have to pay a service teck

Q:Why does my honda civic hybrid sometimes go into auto shut down at lights and sometimes it doesnt?

Because it saves on gas and electric. When a hybrid is stopped a light or tracks, the car charges. It it completely normal, and it is totally quiet when it is stopped

Q:How come the C.E.S. lits every now and then and then stops, and then lits again. I have a chevy blazer 96 if that helps. My friend calls it the stupid light, but does it mean there is something wrong with the car if it does lit or what, yeah we‘ve taken it to the shop couple of times but the sign lits up still every now and then. :( what could be wrong? thank you very much.

something is not right if the light is on. if the light is on take it to an autozone near you and they will scan it for free. make sure that the light is on and don't turn the car off and have them come out and scan it while it is running. chances are it is probably an oxygen sensor causing the light to go off and on. why the hell would you have to take the vehicle to the chevy dealer ? some people who answer questions here are a bunch of retards. the vehicle is an obd2 system which you don't have to be a chevy specialist to read the codes. DAMM! i think coop is right but why stop with the wires and coil ? maybe the computer is defective and the ignition switch is faulty and the crank sensor is toast and the pick-up coil in the distributor has an intermittent short but i think rather than recommending replacing any part or parts that finding out what is actually causing the light to come on in the first place would be a much more prudent idea.

Q:Key features of LED car lights

The expected life of the LED is 50,000 hours, while the tungsten halogen lamp is 20,000 hours, the tungsten incandescent lamp is 3 thousand hours. Relative to the incandescent lamp, LED structure is strong, not susceptible to vibration, the use of light output brightness will not be significantly reduced. The lighting scheme based on multiple LEDs also has the "redundancy" benefit, and even if an LED fails, the lighting fixture can continue to be used. Proper use of the LED (especially the correct control of the LED temperature), can effectively extend the life expectancy of the LED. On the contrary, if the temperature is too high, LED is easy to damage. LED applications also involve many legal definitions in automotive lighting. Most countries have a clear definition of brake light or headlamp failure - light or off. But the use of multiple LED lights, it is difficult to accurately define whether the lights have been damaged. Manufacturers and legislators are defining the use of LEDs.
