This Work?
minor PP to get the flash out of her eye, I'm surprised at how sharp and how good the DOF is at f5, i never use this lens and after this it may have brought itself up a level in my bag.
What Doth Thou Think?

I think the pooch model is gorgeous :D

I use my kit lens a fair bit, mainly because I can't afford more than the two lens I have at the moment, but having said that, the kit lens has produced some lovely images for me, I think it just takes a little more work.

What mode do you normally shoot in?

On Nikon there's P, M, S, A, or one of the PHD modes.

On Canon you have P, Av, Tv, M, or some PHD modes.

Try using A or Av, and then when you make your setting by turning one of the thumbwheels, depending upon your setup and camera, you will be adjusting the lens aperture through which you're going to be shooting.

The lower the numeric value (1.4, 2.8, 3.5, 4, 5.6 etc) then the bigger the "hole" through which you're shooting. The D40's user interface shows this delightfully clearly.

So .... 1.4 has a bigger hole than 2.8 has a bigger hole than 4 ... and so on. the term "stopping down" basically means "making the hole smaller", so instead of using f/4 or f/5.6, you might use f/8 or f/11.

Now .... a bigger hole lets more light through ... but that might not provide, for your lens, optimal sharpness. Different lenses have different characteristics, and you need to learn where your lenses operate best.

This entails shooting, for various focal lengths of a zoom lens, a number of shots, using different focus distances and a range of apertures, so that you get a handle on how you lens works.

But that's a different question, and I believe I've answered this one. :)

I already understand the aperature arrangement on my camera, I just didnt understand the wording 'stop it down a bit'. But I've now learnt more, so thanks for that :)
