Got a burning question?

[ianpinion]

I have question for you. Can anyone recommend a good camera equipment insurance policy or who are the best companies to offer it.

Thanks,

[Amy Davies]

These are all great questions guys (although I'm still not sure what baby pigeons has to do with photography ;-))

Please post anymore you have here and they could appear as Q&A on the homepage!

Thanks,

Amy

Would somebody please explain simply why light diffracts through a lens using an aperture of f16 or smaller and what effect it has on you image?

Thanks,

Light bounces off the aperture blades and gets splattered onto the sensor instead of precisely directed. The narrower the aperture is the greater the area of the blades there is in the way of the light, and so more light is scattered about, and that reduced the sharpness.

It might help if you told us what camera you are using?

You don't say which make of camera you have, but for portraits pick a telephoto lens with a focal length starting at no less than 55mm.
