Can someone help me? I'm having problems with my SB28 flash
since i bought this flash every single picture almost have come out underexposed..!
I know i'm not doing any thing wrong because i'm simply following the directions .
i normally shoot with an F5 body and a the tammron 28-105 *2.8
last week i had a shoot ,it was a shower party for a friend of mine(thanks god).I was asked to take some pictures and i did
use the f5 -my tammron and the crazy flash of mine ..my film then was fuji 800 nghII .
knowing that my pictures might come out under i custom rated my film speed to 400 instead and made sure both the camera and the flash raed that .
the place were the shower took place was a restaurant and the hall had a lot of ambient light (not flauracent).
I shot two rolls of film and made sure before every other shot that the flash was fully rycicled. also went with the distance the flash read that i can shoot with .for example if i used an f6.3 and flash read i can be withen 20 feet from my subject matter ,i made sure i did ,i however noticed that ever time i changed my fstop the camera still used a speed of 60's .
i did think it was a problem because i thought my fstop should only effect the distance my flash is covering ,and i made sure that was followed . still most of pictures came out a stop under .and that is really getting to me..
however some of the photos i took using a bigger fstop like 2.8 came out okay . what should i do ?
a friend of mine said that i should have switched to slow shutter speed in the custom sitting and let the camera sync at slower speed . but what i don't get is why didn't my flash tell me that the picture i just took was under.. since it's cabable of doing that .. and in the future what should i do ?..
by the way my camera and flash came back from a repaire shop a month ago with no problem found ?!

What kind of flash are you using? And What mode on the flah are you using? I.E. TTL, A, M, etc.
Shooting with a lower shutter speed will give you more ambient light in the background of your photos. Normally, when I am shooting indoors, (which seems to have been a lot lately), I shoot with a 1/50 for my shutter speed, and an f-stop between f/2.8-4, using 200 ISO film. This gives me good ambient light in the background and my flash exposes properly on my subject. Oh, I forgot, I use TTL on my SB-26. My F5 tells the flash what f-stop the lens is set at, and the flash exposes for the subject at the given f-stop that is selected.
Please give a little bit of info about your flash, this will help in diagnosing what's going on with your photos. Hope we can help you out. Take care and good luck!!

Adesso thank you for trying to help me .
well the flash is the SB-28 the newest by nikon .
i went out today to my friends lap and we did some test shots trying to figure out what is wrong .
when i shot the shower i used active matrixTLL and i was in apreture prio..
in that case i was moving between f2.8 wide open ,to f8 fairly closed deppending on the situation and how much depth of field i thought i needed .
however i noticed that the cameranever synced below 60s no matter how much my fstop varied ,only the distance bar on the flash would change to give a shorter distance-coverage
with biger f stops(smaller lense openning )
i still thought that i was covered since the flash not once read or marked for an underexposed shot ,and this is somting this flash is able of doing. well today i tryed omthing difrent
i went into the flash setting the one on the camerra body on the back of the f5 where custom bottons are and changed flash setting to slow,with that i was able now to shoot at lower shutter speed .then i moved from active matrix into spot metering instead and in custom number 14 i made spotmetering the narrowest which was in that case 8 and i went ahead and shot to rolls of films 800 fuji nghII in a fairly dark building with my friend as a subject matter .. for my surprise when devaloped the negs every single frame was right on the money .
all the shots where verey accurate and i was reliefed .
only for asecond however .
what i don't get now why xactly does
nikon have the f5 sync at only 60s and not lower i don't get it many are the situation where a slower shutter speed was needed when the camera is locked at 60s and pictures cameout underexposed ,
the other problem i still have is why my flash actrg as
if every thing was okay when it wasn't throwing out enough light to right expose my negs ,,? if any one can help please don't hasitate i will really appriciate all the answares that you may have .

The default flash sync on the F5 (most other Nikon's I believe too), is a 1/60. I think that the only other way to get a lower shutter speed while shooting with flash is to switch to shutter priority, or manual, or to change the flash mode on the back of the body to slow sync.
But this shouldn't be causing the problem that you describe, especially since you were using 800 ISO film. You shouldn't have to change your metering settings in order to get a good exposure. I'm not sure what's going on. It sounds as though you camera is giving the flash the wrong information. I know that you said that you were unsing a Tamron lens. Does this lens have the "D" technology built in? If not, try using a "D" type Nikkor lens to see if that makes a diffence. I would borrow one, or go to a camera shop and ask to use one for a test. Shoot a test roll through your camera and see how the results look.
While most or all Nikon's default shutter speed is a 1/60 in most automated modes, i.e. Program, Apeture Priority, you can override the shutter speed default by swithing to Shutter Priority or go fully Manual. As long as you have your flash set to TTL, it should give you proper exposure every time. For instance, shooting in manual mode, set your shutter speed to a 1/50, and your f-stop to f/2.8 with your flash on TTL. When you fire, the camera opens it's shutter, the lens calculates the distance to the subject, the flash fires for that distance and f-stop, and the proper exposure is rendered through all of the calculations that the camera, lens, and flash take. While this is an EXTREMELY simple explanation for a complicated procedure accomplished by the camera, it does work.
I hope this helps out somewhat, and I apologize in advance if I've confused you in anyway. Maybe someone else here has some input that they can come forth with.
Take care, and good luck.

The sync speed for flash can switch from 1/250 - 1/60. However, on the f100, there's a custom setting which will allow the slower speeds to come into play without using slow sync and having to deal with greater-than-one-second exposures. You might want to check.
I doubt the Tamron could be feeding such wrong information that the pictures were improperly exposed by it. Usually, the D information is used in situations of high contrast where the flash might "burn out" (ie: the Bikini Atol effect - where people look like they're watching the A-bomb test) by allowing the user to point a focus point on the main object and using that to modify the otherwise "correct" flash exposure.
How about this: Set the flash to Automatic (using the onboard sensor) and set your and flash to match aperatures (with the camera at 1/60 of a sec f8) and make sure you set the flash to use f8. Take some shots and see how well the flash judges the exposure without using the matrix computer.
