Question about Nikon Speedlight SB-600 TTL Flash

1 Answer

Sb 600 under exposure.

Hi, everything is underexposed with my sb 600. it flashes but only outputs a tiny amount of light. I have tried using it on two d80's and a d70 but im still having the same problem. It seems to work fine when i remove it from the hotshoe and fire it manually. I've also taken it into my local photographic shop but they hadn't come accross the problem before.

Re: sb 600 under exposure.

You probably haven't changed the camera and/or flash back to TTL mode from wireless mode.  Make sure they are both set to TTL, not commander mode and you should be fine.  Note that the LCD on the flash will indicate which mode it is with a little graphic.  On the D70 you had to switch between TTL and Commander mode to set it up to work using the built in flash as the commander, so you just have to switch back.

Sporadic off camera flashes triggered with pocket wizards will not be as obtrusive as you may think. IMP, It's just as obtrusive as the onslaught of small digi cam flashes that usually occur..Cheerss!!....

My nikon d90 doesn't works when i put the flash sb-600

Could you provide some details? How does it not work? Does the D90 not turn on? Does it take a picture but the flash doesn't go off? What exposure mode(s) are you using?

Why does the flash on my Nikon Speedlight Sb-600 flash twice before it takes the actual picture?

It's called a pre-flash. It's so the camera can judge the settings needed for proper exposure.

I put fresh batteries in my sb 600, i took a few pictures and then the flash was not as powerful and 2 red lights kept flashing on the front, why?

Ok, there are several things to consider. First of all, don't use standard alkaline batteries, the flash needs a lot of power and will drain those quickly. Use either lithium batteries (most powerful non-rechargeable) or invest in NiMH rechargeable batteries. Those would be your best choices for AA's.
Now to your flashing red lights - on the Speedlight flash they fulfill 2 functions, one is as auxiliary ready lights (if used as wireless remote flash) but the blinking in your case points to their other function - it blinks 3 times to indicate possible under exposure of your photos at maximum output level. It's basically telling you that the flash was not strong enough to properly illuminate the scene you tried to shoot. That doesn't necessarily mean the batteries are going flat, but you could simply be out of range of the maximum flash power. Your flash has a guide number of 30 - that means at a zoom head position of 35mm (if your lens is at 35mm) and your ISO is 100, then the maximum range of the flash is 30m (approx. 68ft). If your subject is further away, you would get an underexposure warning (3 blinks of the ready lights).
Hope that helps explain some things.

The on-camera flash has to flash if you want it to be in commander mode. That's how it sends commands to slave flashes. Set to "--", that's all it does, the flash will not affect the picture.

If you want to operate remote flashes without any flash from the camera, you'll need to invest in a third-party wireless commander and triggers.

The flash is not in sync with my nikon d40 anymore. It fires first. Pictures come out dark. The camera itself takes great flash pictures

It sounds like you're trying to use the SB-600 off camera, as a slave flash. While the SB-600 does indeed have slave capability, the D40 does not have the ability to function as a commander. Thus, the SB-600 is being triggered by the D40's pre-flash.

As stated above, the D40 does not function in commander mode. You can mount an SB-800 or SB-900 flash unit, which will function as a commander as well as a flash. Or you can mount an SU-800 commander unit.

Alternatively, you can switch the D40 to manual flash mode so as to eliminiate the preflash. However, you will then have to calculate the proper exposure yourself.

Recently my canon speedlight 580 EX II TTL has been acting up...especially in low light situations. About on in 30 shots actually has enough light in them...the rest of the time the shots are...

that the camera/flash set-up I use ... there are many variables - iso/metering setting/shutter settings/flash settings .
If it's a flash function problem, try this to isolate it - first, with the diffuser/reflectors tucked into the flash head, and the head straight up, with the flash set in master mode, turn it on and look on the back screen. push the mode button til you see the ETTL in the upper left of the screen .. then press the set button in the center of the dial and the nuber in the center of the display should flash (+0) while the light is flashing, rotate the dial to change the setting (i usually under power by 1/3 stop. Play with the exposures a few times to get the feel for what the EV shifts do to your exposure. generally speaking, for interior low-light, i prefer to bounce off the ceiling (if low ceilinged), if there's too much direct it will give you an uneven and predominantly underexposed image.
if you prees the mode button you will come to the same options for adjusting the output in manual mode, but it will not work with the autoexposure in the camera.
Try playing with the ETTL settings
I think the problem may be that you have somehow altered the power output setting on the 580.

SU-800 and SB-600 line of sight

Remember that the SU-800 works by sending out an infra red beam as the trigger pulse, when out doors available light can swamp the sensor on the side of the flash with too much light, therefore the flash cannot "see" the pulse from the SU-800.
Also if you refer to the manual, you will find nikon recommends working within approx 30 / 60  degree angle of the sensor, so if you were working behind the camera with the flash it would have had even more trouble.
As you found when you used your hand you strengthened the output beam for the flash to be able to pick up the pulsed output beam. You may need to create some kind of hood, to place in front of the SU-800 to direct the beam in the direction you need it to work.
Hope this helps  Ian
