Hello can someone explain the term "shooting wide open"?

Thanks

Shooting wide open is where you shoot using the largest aperture the lens can handle. Which will give you an image with real shallow depth of field (dependent on lens and focal length). So say you are using a 50mm f1.8 lens. Shooting wide open would be taking a picture at F1.8.

the term "shooting wide open" refers to the biggest aperture your chosen lens will open to..ie: f2.8.f3.5 etc...

some lens have a constant aperture ie: 70-200 f2.8

and others alter as you zoom in and out..ie: 17-70 f2.8-4.5,so f2.8@17mm and f4.5@70mm

so wide open = smallest f number of your lens

hope this helps

so shooting wide open in a dark spaces, this allows more light in and also allows for faster shooting? does it still give the shallow depth of field?

thanks

It might be worth mentioning that some lenses are not great 'wide open' whilst others perform well. Almost all lenses are sharper and show less chromatic aberration when stopped down a little.

A good example might be the Canon 50mm f/1.4 vs Sigma 50mm f/1.4.

The Canon is very sharp stopped down a little - say to f/2.0, but can be a bit poor @ f/1.4. The Sigma is pretty sharp @ f/1.4 and if you nail the focus you can get some great results isolating subjects from their backgrounds.
