  4. Camera sensor size 1" vs full frame

Camera sensor size 1" vs full frame


1 month 3 weeks ago #761920 by Petroguy
In real world speaking, would a photographer who is a hobbyist see a large difference between a shot taken with a camera with a 1" sensor vs the same shot with a full frame camera?

To be absolutely clear, a 1" sensor isn't one inch in any dimension.

A 1" sensor is only 13.2x8.8 millimeters.

From Wikipedia :

"Sensor sizes are expressed in inches notation because at the time of the popularization of digital image sensors they were used to replace video camera tubes. The common 1" outside diameter circular video camera tubes have a rectangular photo sensitive area about 16 mm on the diagonal, so a digital sensor with a 16 mm diagonal size is a 1" video tube equivalent. The name of a 1" digital sensor should more accurately be read as "one inch video camera tube equivalent" sensor. Current digital image sensor size descriptors are the video camera tube equivalency size, not the actual size of the sensor. For example, a 1" sensor has a diagonal measurement of 16 mm."

So, yes, there would be a substantial difference between a image captured with a 1" sensor and an image captured with a 'Full Frame" sensor, in terms of depth of field, image noise, and dynamic range.

This is a comparison of Sony's RX100 VII (1" sensor) with its A7R IV ('Full Frame' sensor) (Both released at about the same point in time.) (Click on the 'Measurements' tab, then the 'SNR 18%' and 'Dynamic Range' tabs.):

Here's a comparison of the depths of field to be achieved when using a 1" sensor and a 'Full Frame' sensor:

So can a 1" sensor photo have artificially be made larger with AI?

Different question.

Certainly, an image can be manipulated to have a higher resolution. Also there are plenty of processes that attempt to remove image noise. But I know of no such attempt to increase the dynamic range of an image, which could possibly be described as making something from nothing. And I suppose there could be an effort to blur some things that are in focus while leaving others sharp, and thus altering the effective depth of field, but I think that would take quite a lot of effort.

I think it would be a lot easier to just get a camera with a larger image sensor.

Thanks Tcav, it was more of a general curiosity as I have noticed that certain softwares claim they are able to 2,4, even 6X photo resolution and curious would that translate to people saving $$ on physical servers and go the software route?

I've had a lot of luck printing smartphone images at 13"x19", so upscaling images isn't a problem.

All that other stuff can be, though. Most notably, attempts to remove image noise frequently diminish detail as well.
