Flash help

[Ziggy]

Looking for a bit of help in regard to flash.

What I want to know is should I be using a flash indoors with a Nikon 35mm f1.8. In auto mode the camera wants to fire it , but in P mode without the flash the pictures do look ok , apart some some being a bit blurry as my subject (son!!) moves about a bit.

Would the flash reduce the blurry parts, or do I need to make the shutter faster to do that, and if I do that does that then mean I need to use the flash, a tad confused and any help appreciated.

few questions in there, basically it depends on what you want. i think auto mode wont use the wide apertures due to keeping more of the image sharper, this will mean you will need flash. as for blur, without seeing a pic, it is difficult to tell whether it is a) camera shake due to slow shutter speed b) missing focus at low aperture or c) motion blur from your suns movement.

if you used the flash, your f stop can increase, giving you more depth of focus and you could increase the shutter speed. the flash would also help freeze movement as well.

thanks for that.

Basically I only want him in focus and the rest of the background etc out of focus, that is why i was using the f 1.8, unless I have got that totally wrong, which knowing me I probably have!!

If I use F1.8 , what kind of shutter speed should I be using, both with and without the flash, any ideas?

depends on what lighting there is, try sticking the camera in "A" mode(i think it is A, Av on Canon, Aperture priority)), and let the camera decide, if the shutter falls below 1/50th up the iso, inside i normally end up somewhere round f1.4-f1.8, iso 1600 and a shutter of about 1/50~60th. but you might have a brighter room

If you have blur, you must have to much ambient light with a slow shutter speed.

manual iso 100 f1.8 shutter 1/60 flash in ttl (auto) mode

take pic if bg to bright raise shutter speed to anywhere below 1/250 (maybe 1/200 I don't know ** cam) if too dark up iso

the camera meters for the ambient light then the flash tops it up, this is where the blurryness comes from (the camera is retarded and should be let to make as few decisions as possible)
