Can someone please briefly explain the concept of infinity to me? Of course, as it relates to photography! (otherwise we'd be here all day....though I may be here all day anyway.)
Because your focusing engine will find objects closer that the furthest point and is designed for sub infinite focus. Besides it is just so natural to manual focus the distant objects in your FOV. Or sometimes just set it for X number of feet from where your shooting. I'm still experimenting with this myself.why can't we "focus on infinity" in AF mode?
Being a layman, perhaps. Infinite focus is for times when you just want to capture the whole scene as is with everything, (or nearly everything in focus). A field of flowers that also has an interesting landscape and mountains in the distance for example. Conversely DOF shots are more creative in nature as you have explicitly sought out to soften backgrounds or to isolate an subject.Are you able to explain it in layman's terms
Loosing me now, but be aware large apertures (small f/stops) will allow too much light in (scatters) and therefore blur objects outside the focal point. Small apertures (large f/stops) will limit the amount of light and are key to creating images with near infinite focus.how it relates to everything else in the photo etc...
I'm not a pro either, but...Being a layman, perhaps. Infinite focus is for times when you just want to capture the whole scene as is with everything, (or nearly everything in focus). A field of flowers that also has an interesting landscape and mountains in the distance for example.
Infinity means in a simplified explanation, that light which comes from an object at infinite distance is parallel. hence to focus, the lens has to converge this parallel light in one spot on the film/sensor.
That makes sense. However, is "infinity" (in photography terms) a certain distance away? Or does it depend on the lens? Is there a way to find out how far away infinity is for a given lens?
What lens consider "infinity", of course, would differ from lens to lens. "Infinity" for a 28mm lens would be different from that of a 200mm lens, as the 200mm lens is built to zoom into and focus objects much further away.
