And that is somewhat true, but it’s more nuanced than that.īe warned! Photography terminology is a mess and correlation established in experiments is often mistaken for causation.
#Big aperture vs small aperture for blurry how to#
If you look up how to achieve this shallow depth of field, most photography resources will say “use a wide-open aperture” and “use a long lens”. The transition from sharp to burry is clearly visible, especially with a “Find Edges” filter applied. area) that is in focus is shallow and creates “separation” between the foreground subject and background elements. Photographers calls this a “shallow depth of field”, because the field (i.e. Having a blurry background is a common technique in photography to make the viewer focus on the subject and not get distracted by elements in the background. It turns out that both these questions have closely related answers and they also explain why the background blur that recently got added to most camera phones is fake. Later I wanted to figure out if the significantly bigger sensor in the Ricoh GR III will get me better background blur than the Canon PowerShot G7 X Mark III. Originally, I wanted to understand why smaller apertures make your image sharper. If you find something, please give me a shout.Īlright, I will admit: The titular question is not actually the question I had when I started writing this article. I tried my best to do my due diligence and be upfront when I’m simplifying things, but I might still have gotten things wrong. Turns out the reason this is done artificially is physics more than anything else.īefore we start: I am not a lens expert. Portrait mode artificially blurs out the background of an image to make it look.
