How to rectify??

Hi anyone noe's how to control the 12-24 lens with flash??? It's usually when i use flash, the front subjects will be bright. then the rest at the background will be black. Even if i set my flash to TTL BL, the background's still black.

with my flash on, my default's 1/60s. shd i set it to 1/30s??

the main issue is know how you balance your flash with ambient lights, if it is greater than 4 stops, nothing much you can do if you can't bring them closer.

If shutter speed is not a concern, set the flash to slow-sync.

I second of that.

Also, consider off camera flash. Nikon CLS is .

ur shutter speed and iso setting are the main crux.

Did you try diffusing the flash??

No use.. The power of light falls off by square law. You will need to use multiple bounce flash to illuminate the place uniformly.

Just to check the obvious: at 12mm the built-in flash may cast a shadow... (at least that's the case for my D50.)

Thanks for the info...

Then how about setting it to rear fill flash? You'd probably have to get a tripod though.

Suggest you read up more on how to use flash and then experiment to understand it. Couple of tips for you though

- Flash only lights up one distance the correct amount. As Isisaxon mentioned earlier, light falls off by inverse square of distance. If the flash lights up your subject correctly, it obviously won't light up correctly the background which is 2 meters behind your subject, for example.

- When you use flash, there are two exposures - one for the flash and the other for the ambient light. Ambient light exposure is controlled via the usual ISO, aperture and shutter speed. Flash exposure is controlled by flash power, aperture and ISO. You'll need to get both exposures right, if you want your subject and background properly exposed (and adjust accordingly if you want your subject correctly exposed and your background a little under etc)

- TTL-BL is balanced fill flash. If your ambient is underexposed, the camera will try to "balance" the flash exposure as well and thus cause your subject to also be underexposed.

In short, know your equipment and it's limitations, @ f/4 the amount of light needed will differ, the angle of diffusion will help, but only to a certain extent.
