I'm going out to take some snaps, what setting should I use on my camera?

I'm using a Nikon d70s with a Sigma 70mm 1:2.8 DG Macro lens. I'm shortly going to take some pictures, whilst the sun is at it's strongest. I want my images to look warm, almost fantasy like. The images are going to be of a friend that I've roped in to be my model.
What F number and shutter speed etc should I use to produce a decent picture? I'm currently still a little shaky on this as I'm still studying!

Try AUTO

Look up the Sunny 16 rule.http://en.wikipedia.org/wiki/Sunny_16_rule

We can't give you an exact setting because we're not there to meter the light. Use your histogram too, If the bars are too far to the left, your image is over exposed. Too far to the right and it's underexposed. And shoot at 100 ISO

There's NO all powerful setting for EVERYTHING… Like all things, it comes from practice and learning about your camera and learning the basics of photography!

if you think that there's an easy way to get what you want from photography, then you are going to be VERY disappointed…

learn and develop your skills…

Other than refering you to the Sunny 16 rule, we can;t really help you. You need to get a better grasp on exposure.

Pick up a book called "Understanding Exposure" and you'll have a much better understanding of the interaction of ISO, Shutter speed and aperture.

One thing I would suggest is that you read your manual and look at the section that talks about the built in light meter. Use the built in light meter in your camera to determin what your exposure will be and adjust everything accordingly.

Well actually if you want the warm dreamy look you should be going out when the sun is lower and passing through more atmosphere. This gives a lower contrast and warmer look that you are looking for.

This was shot at mid afternoon, in Jordan, around April/May time. You can' see the light isn't that flattering.

This was shot in the evening, in the UK, in June. I apologise for the excessive post processing, but the light is much warmer and more appealing.

Edit - Forgot to say about settings, it actually doesn't matter so long at the light is right. Though it's best to shoot in RAW.
