Advice on motion blur when photographing model

[jamiebonline]

Hi all,

Hope everyone is having a nice Sunday. I am photographing a model this evening ( between 90 minutes and 30 minutes or so before sunset ) and I want to bring my tripod so I can minimize blur caused by camera shake. I want to be able to reduce the shutter speed of course to let in more light but how slow can I go? At what point will the slightest movement of a stationary model register as blur? Or what other issues should I consider. Some advice would be very welcome.

Thanks a lot

J

Consider a longer exposure to record the background ambient light and a flash to freeze the model. Another option rather than just upping the ISO.

I think its something like double the focal length? So with my 50mm I wouldn't shoot handheld less than 1/100. Although tbh I shoot a bit faster because I need more practise with my handheld technique.

the rule of thumb is 1/focal length, but it's not required as the OP has a tripod.

If you want to get all that ambient light in then I would follow Nick's advice and use a fill flash (subtly)
if you just meter for the model then you'll might get washed out colours or lots of light bleed around the model ( i think)

A limit of 1/focal length applies to reducing camera shake in the absence of any image stabilisation system, some of which are good for 4 stops.

However... anything slower than 1/60 may well show up movement of the model unless you have a good one. Even 1/60 is a bit slow for close work. Flash can mitigate a fair bit, depending on what the ambient light is like.

It will still be quite bright unless it's a very overcast day. However, just increase ISO until you get the shutter speed you require at the aperture you require.
