Question about Vivitar 283 Flash

1 Answer

Flashes but image is dark

The flash seems to work fine but the image has a dark shadow on it like it never had a flash at all. (does the round button "auto thyristor" have anything to do with this problem?) and just what is that knob used for anyway???? Thanks

Turn the front black knob and check to see if the front window is not dirty.

Sounds like they are a little out of sync. Try adjusting the timer settings.

Nikon SB600 flash won't fire

There may be a short, or it is arcing over,

Test fire it in the dark to see if you can locate the arc. If no arc, it is likely arcing in the charge capacitor or what might be left of the thyristor.. Which could mean a broken contact, solder connection or wire..

SB-800 makes strange noise and over exposes image when it does work

The flash has settings you will have to read your manual
the camera does the exposers not the flash
set your cameras appuatue to a high number and speed fast then shoot if you knew how to use your camera you would know the flash is uesd for filling in shadows and imitating the sun which is bright. Good luck

The 580EX is firing but images comes out completely dark it just started happening in a session around 2 hours ago........i put it on another camera the 40d still the same problem what can this be?

When the flash mode TTL. Then this situation can occur if the proximity is working with other studio flash light traps. Your work makes flash another flash while TTL metering. And when is your main flash another flash did not have time to recharge.

I mounted the Canon 580EX II to my Canon 5D Mark II. When I using Manual Mode, I can't set the shutter speed more faster then 1/200 sec. Is this problem normal/limitation of it?

Yes. If you were able to set a faster shutter speed, then you would not expose the entire frame and would have the shadow of either the first or second shutter curtain (or both) partially masking the frame.

At higher speeds, the shutter is never fully exposed: before the first shutter curtain has finished travelling across the frame, the second one has stated it's journey. All SLR's have this issue and on some older models you could only use a maximum 1/60th of a second.

In practice though, in dark conditions the "slow" shutter speed does not affect exposure as the true exposure will be determined by how much light the flash puts out, and it puts this light out in as little as 50 microseconds (50 millionths of a second) for a modern electronic flash bulb.

Faster shutter speeds can be used successfully, but only with flashes which operate in high speed mode. What they do is to make the flash burst seem longer by rapidly firing the flash bulb many times. This trick can ensure that there is sufficient light to expose the frame at the highest shutter speeds. Shutters which operate at, say, 1/4000 may seem fast, but compared to the speed at which a single electronic flash burst operates, it's an eternity.

Underexposed images

How is the camera set? How is the flash set? There are too many potential problems to answer without more info like what brand and model camera and flash, what settings etc. Take the camera to a camera store and ask them for help.

Flash fires but picture is dark

Looks like the tube is weak. Then it has to be replaced. If you are in India, I would have solved your problem. Johnsheen, 9341932677, Mysore

Sb 800 and sb900 overexposing

It might be you are not making a good contact on your camera and flash .

Are you using a cord to get the flash off the camera . If so the cord could be intermittent .

Sigma Elec Flash EF-530 (so) DG Super used with Dimage A2 camera

The light only flashes in wireless mode or in slave mode. It basically lets you know that the flash is ready to fire. At least that is my experience w/ the 530 DG Super.
