Flash problems ?

[enforcer533]

Hi guys

i just bought a external flash for my A230 brand is sunblitz 4000. When i shoot in auto mood the picture
always come out badly illuminated. I have to use Manual or shutter priority mode. When using shutter
priority mode any thing above 1/160 shutter speed will be badly illuminated. Anyone have this problem
with cheap flash before ??

How bad is 'badly illuminate'?

Well, you know what they say... you get what you pay for...

Also, keep in mind the flash sync speed of your body.

Here you go:
Camera tech data for Sony Alpha DSLR-A230

Flash x-sync speed for the A230 is 1/160s. Anything higher than that and you risk issues with your shutter curtain obscuring the image.

if using TTL flash, its better to use in M mode so u can set your shutter, aperture, ISO and leave the flash to determine the flash power.

that allows u to have more control in terms of the type of pic u want to get.

as mentioned, your camera's max sync speed is 1/160. so anything above that, your guess is as good as mine - u probably won't get a good pic.

also, need to have realistic expectations abt flash, whether cheap or expensive flash. for example, its not realistic to shoot at F11, ISO200, 1/160 at a subject at the far end of a dark room with the flash bounced off a high ceiling and expecting to get a magically bright picture.

when shooting indoors for family / friends gatherings, i normally bump up the ISO and reduce the shutter speed so the flash don't have to work so hard and to allow me to bounce the flash so i don't get the "deer-in-headlight" effect by blasting a flash directly into their eyeballs. higher ISO and lower shutter speed also allows me to capture the ambient light better so i get a nicer BG. thats just my newbie preference

sony cam ?

Haha thanks at least that clear my doubt. But will this happen to build in flash ?
coz i bought a cam from this forum with a spoilt Flash..

it affects ALL cameras.

it affects ALL cameras.

So be it what brand of flash i use, the shutter speed goes above 1/160
i will still get badly illuminated pictures ?

I think posting a sample photo will be better.
Its rather hard for me to understand what 'badly illuminated' means.

"spoilt" as in doesn't fire off? or "spoilt" as in doesn't expose correctly?

the on-board flash will follow the same max sync speed.

So be it what brand of flash i use, the shutter speed goes above 1/160

unless your camera and flash supports high speed sync. not sure abt sony equipment.

but u already using flash already - shutter speed set so fast for what?

go readup on how the shutter curtain works, before and after x-sync speed.

You can get exposure problems, "black sections" in the pic, etc. This is NORMAL for all DSLR cameras. If you need a faster flash synch, you need a higher-end camera. For example, an A77.

Here's a good example of what can happen if you exceed the x-sync speed:

Hi bro spoilt as in totally cannot work ..

 

[enforcer533]

hi guys i think i knw the reason behind it when ever i on my flash,
the shutter speed will go 1/60 and aperture will be F5.6 stagnant.
is that normal ?? reason y i get image darker then usual is because
of the F5.6 . when i off the flash, it goes back to normal.

Hi all the 1st picture was taken in auto mode
while the 2nd pic is in manual mode. Auto always
produce picture which is poorly lid up.

 

[kei1309]

your photo in Auto mode... the f-stop was f5.6. on Manual it was f3.5

understand now?

 

[tecnica]

was the flash in TTL mode when you took both pics?

Yup i know in manual was 3.5 but by looking at the image
is it normal for the lighting of the flash on auto ?
