Hi people ! I am trying to get to the bottom of this diemma !

I am using x2 500watt lights with umbrellas (gave up on the softbox)

I'd like to be able to use some nice fabrics in pale colours, as at the moment I can only seem to master the black - cause it's easy !

I am shooting on F9 1/160 and also F8 1/200

I can't seem to get blurred backgrounds due to the F being high, and I have tried to move the backdrop away from the subject, but still a no go.

what I am I doing wrong?

I see so many gorgeous photos of babies with soft blurred backgrounds, but they seem to be taken using natural light, and a low apeture, but I just cant get that with my studio stuff.

how does one get a shot like this, using studio lights? I don't like the high ISO's needed to shoot with natural light, and I don;t always have natural light available.

(I hope it's ok that I used someone's photo I found on the net? if not, let me know and I'll remove it)

You are using continuous lighting as opposed to flash,,am I right??

If you are,,why don't you just drop your ISO and open your lens up from F/9-8 to F/5.6 or F/4.. Or increase your shutter speed and open your lens up..

Describe your light equipment in more detail.

Generally, you can lower the light intensity in a number of ways (presuming you've turned down the power of your lights as much as possible.

You can purchase inexpensive neutral density gels to tape or pin over your light heads.

You can purchase a couple of yards of rip-stop nylon from a local fabric dealer and drape it over the front of your softbox (if you use one). Usually each layer of nylon will reduce output by a stop.

and I'm using the 24-70 f2.8L

I have the ISO at 100 - the lowest I can go !

I will try turning down the power and opening up the lens -

Those aren't continuous, they're strobes.

what's the difference?

these ones, you turn on, they are lit all the time, and then flash when the shutter is hit

If you space you can always shoot with longer focal lengths. Also keep subject away from bg. Use good quality back drops with nicer patterns. They help with ghetting blur and less prone to wrinkles.

Here is one shot with 30d at f8 in my living room. Taken with 70-200mm at 100mm.
