F STOP VS T STOP HOW TO
The first step in learning how to read f-stops is understanding what a stop of exposure is. Lenses made for digital cameras will usually have f-stops in increments of thirds. This lens only has full stops available for adjusting the f-stop. f/16 or f/22), the greater your depth of field and the greater amount of your image will be in focus. The more open your aperture opening (like f/1.4 or f/2), the shallower your depth of field the more closed (i.e. Depth of field is the amount of your photo that appears sharp from front to back.Ī very shallow depth of field blurs everything but the point you focus on.Ī deep depth of field will keep most of the scene relatively sharp.Īs you can see from the f stop infographic above, depth of field and aperture diameter are intimately connected. Next to the f-numbers is an arrow referring to the depth of field. The wider the aperture – the opening in the lens – the smaller the f-number.įor example, in the chart above f/1.4 is quite wide open (a ‘wide’ aperture), while f/16 is little more than a pinhole (a ‘narrow’ aperture).
