#F stop guide iso
Many of us grew up with the mantra of ‘use the lowest ISO possible,’ but camera technology has moved on so much today that high ISOs are no longer a bad choice. His latest book, 52 Assignments: Black & White Photography, is out in February, and he’s also on YouTube wish I had a pound for everyone I meet who thinks that high ISOs are the work of the devil.

Street specialist Brian Lloyd Duckett says it’s time to reevaluate how you use ISO and how working in Auto mode can free up your photographyīrian Lloyd Duckett is a pro street photographer and Fujifilm ambassador who runs workshops via. Yes, you can shoot and chimp the screen, but that takes you out of the moment. Remember, a DoF preview on a DSLR will progressively dim the brightness, but with an EVF, it’s obvious, and you can see if you’re getting enough subject sharpness or context in the background. Obviously, it becomes second nature as you learn what works for you, but an EVF shows depth of field in a way that an optical viewfinder can’t.

#F stop guide plus
My Rotolight NEO and AEOS lights can be set to low output and work brilliantly with wider apertures, plus – unlike flash – you can see exactly the effect you’re getting before you shoot. Alternatively, use lower-powered flash heads, or – like me – switch to LED lighting. Flash power can also be a problem – there can be too much of it for wider apertures even at the lowest output, so either fit an ND filter to the camera or a diffuser to the light source. Using modern cameras with fast electronic shutters capable of exceeding that can solve the problem.įitting an ND filter to decrease the light intensity entering the camera will help, too. Historically, that was down to the limits of a camera’s maximum shutter speed, typically 1/8000sec. Using the wider apertures can be problematic in bright conditions like midday sun, where minimum ISO and highest shutter speeds can’t give you correct exposure values. To offset that, remember you can compose with out-of-focus foreground elements, too. Completely blurred backdrops also mean images lose depth. You can still work at very wide apertures but try to use shorter focal lengths or step away from the subject a bit. I find that shifting to f/1.8 or f/2 for men helps to keep their larger features in focus.
Take care that you adjust the aperture for the size of the subject’s head, too. This portrait needed to show movement in the background, so the aperture was stopped down to f/22 I often shoot character and environmental portraits, so I want a background to be recognisable, even if it’s out of focus. If all you have is a completely soft background, images will lose context. Novices often go too far with background blur.

Shooting with a very shallow depth of field is something people associate with a more refined and professional look. If I’m shooting a wedding party or a family, I want separation for the subjects, but everyone needs to be within the focal plane and remain in focus! There are also times where I want to push the shutter speed lower to show movement in the background, and smaller apertures will help with that. Stopping down is also important with groups. Longer focal lengths, like a 135mm or 200mm lens, can create a shallower depth of field, so smaller apertures can help keep both the whole of the subject in focus and improve background context. Though I like to work at wider apertures, there are plenty of times I’ll stop down to more middling f/stops like f/5.6 or f/8. Though an aperture of f/1.4 is used here, there’s still plenty of context to the background When to go deeper
Ultimately apertures such as f/1.4 or f/2 can bring a more cinematic look, which I love, but doing it successfully is about more than dialling in a number. Yes, it keeps my shutter speed up and means I can shoot more easily when available light is low, but it also adds separation and emphasis on the subject. Like many pros, I tend to work at wider apertures for a variety of reasons. Find out more at Fundamentally, the aperture is a tool to let more light or less light into the camera.
