Nikon SB-700 Speedlight - Why does the Effective Flash Output Distance display increase when I dial in -(negative) EV values, and decreases when I dial +(positive) EV values? Surely it should be the other way around.

When you dial in negative EV values, you're asking the flash to provide less light than the meter thinks it should. Since you're asking for less light on the subject, the same amount of light produced by the flash can reach a subject farther away.

Conversely, when you dial in positive EV values, you're asking the flash to provide more light. This reduces the maximum distance at which the flash can provide that much light.

    Thanks, I sort of get it, but I can't get my head around the fact the the flash can throw out less light, and yet illuminate further?!

    It's not necessarily throwing out less light. If you need less light (as with a negative EV), the same amount of light goes farther.

I had the same problem. You locked your flash by mistake if you have a lock symbol on your LCD. Press the ON/OFF & Sel buttons simultaneously & the lock symbol will disappear. Then reset your unit by pressing Mode & ON/OFF simultaneously for 3 second & you are good to go!

SOURCE: Nikon Speedlight SB-600 keeps firing

I believe that there is a safety feature built in that if the voltage in the capacitor gets too large the flash will fire, to prevent damage, could be this that is faulty, if it is a new main circuit board is required.

How to install a Nikon SB-700 AF Speedlight Flash for Nikon Digital SLR Cameras


Basically, you put batteries into the flash, put it into the flash mount on the top of the camera, turn everything on, select a flash mode, and start shooting.
The flash comes with a detailed manual describing its operation. There is a section in the camera manual describing the various flash modes. The SB-700 is fully compatible with the Nikon iCLS system, which includes the D3100.

Since you asked a general question, I can only give you a general answer. If you have any specific questions, please feel free to ask them.

Flashing negative sign


A few suggestions for outdoor flash too bright with SB-600.
1 - If flash is in the auto mode, try hitting the (-) symbol a few times to lower the flash output
2 - Quick fix for close shooting - pull down the diffuser. You loose about 2 stops of flash light and effect is much softer. Don't forget to raise it later or you might think you have the opposite problem
3 - On the camera side, you play with your ISO. Depending on the scene, changing ISO can increase or decrease effect of flash vs background. This can be tricky to predict in auto because the camera is doing calculations of its own.
4 - You can put the camera in aperture mode and set your apeture so that you get a good balance between flash and ambient light. The camera will adjust the shutter speed, which increases or decreases the effect of the background - while the flash remains a constant. This can be very effective in tricky lighting situations, but be prepared to take lots of test shots to get it right.
5 - You can put the flash in manual mode. That will give you a consistant fixed reduced flash output regardless of what the camera tries to change. You have to keep checking your display to see the effect, but with camera in auto this can be a winner.
6 - Finally, you can go "old school" and put both camera and flash in manual and find your best combination. When I'm pressed for time in tricky conditions I often do this by finding a good setiting for a fixed distance, and then adjusting my apeture up or down as I shoot closer or farther things. We had to do it like this back in the day, and with the histogram on the display, I can get dead on where the camera "brain" would get tricked.
