When i used flash the picture always look flat and dull , is it possible to produce bokeh picture with flash ? if yes how to setup the flash , camera , and the object ?
What lens used and settings too?
There is no such thing as "bokeh picture". Please read up on what bokeh actually means.
As for your issue, you are trying to achieve a shallow DOF while still using flash, but you have not told us anything about the settings you used in the picture. If you want us to help you, you need to provide enough info.
i believe u are using auto modes (protraits, landscape, sports etc) hence when is dark, flash automatically pops up.
if u switch to AV mode, shooting at f2-f2.8, ISO bump up to 800, dun use any flash. The results will be better. Try it. Since you are using a 50mm f1.8 prime, u dun really need to use flash to shoot in the dark/night. Shooting at wider apertures (f1.8-2.8) + bumping up your ISO, is very capable enough.
broken picture have, bokeh picture don't have.
anyway, try to understand the basic photography first,
get correct exposure first,
get decent composition first,
learn how to use flash properly first,
nice boken is like icing on the cake, cake is all the basic about photography, so icking can always come later.
ISO 800 is still quite acceptable on your existing cam (as compared to my previous cam 450D).
try my method and compare yours.
u can do long exposure as well. shoot with tripod, f8-f11 in AV mode, ISO 100.
As highlighted in your pics, there is nothing wrong shooting wide open at high ISO, but it looks like the lens is at hyperfocal distance already, with little OOF area to show.
Basically, TS needs to read up on fill-in flash techniques while taking note of hyperfocal distance of his lenses.
Study the basics and understand how they all relate. Once you have that down you can work on using your flash...
Yes correct engrmariano , your picture represent the one that i want to shoot .
It's very nice picture and has bokehlicious in the night .
I want to have a clean night image with shallow of DOF during the shoot .
Do you used built-in flash ? and what kind of diffuser do you used for that one ?
His picture used no flash. He used ambient light, just bumped up the ISO.
I see now , so no need flash to get night picture with shallow depth of field , just bump up the ISO number . But how the object has bright on the other side ? or maybe it has the external lamp beside accidentally ?
it is the same as bokeh in the day, when u shoot in daytime with wide aperture (AV mode f1.8-2.8), those blurred background is the same you get at night except they become "round" balls of light.
hence earlier in my post, i ask u not to use flash but rather shoot at wide aperture (you can shoot at AV mode from f1.8-2.8) then bump up your ISO to 800 (try not to go beyond 1600 in your case since your camera may show more grains if more then 1600).
that is called ambient light...
Do u knw what ISO do?
Maybe u have to read up more...
