Sony a6300 — pushing in post at low ISOs, single shot shutter

March 17, 2016 JimK 2 Comments

This is part of a long series of posts about the Sony a6300. The series starts here.

So now I’m going to do a series like that of the preceding post, but with a big difference. I’m going to leave the exposure the same, vary the ISO in full stop intervals, and push the images in post to make them have equal brightness.

I started at ISO 3200 with a normal exposure, left that exposure the same, and made images at ISO 1600, 800, 400, 200, and 100. Then, in Lightroom, I pushed the ISO 1600 image one stop, the ISO 800 image two stops, and so on, until I got to the ISO 100 image, which got a five stop push.

Here is a large view of the result:

ISO 3200
ISO 3200
ISO 1600
ISO 100
ISO 800
ISO 200
ISO 400
ISO 400
ISO 200
ISO 800
ISO 100
ISO 1600

Not a lot of difference, huh? Let’s zoom in on a 200% blowup:

ISO 3200
ISO 3200
ISO 1600
ISO 100
ISO 800
ISO 200
ISO 400
ISO 400
ISO 200
ISO 800
ISO 100
ISO 1600

Not much difference, either. There should be shadow noise differences, though, since this series crosses the ISO 320/400 conversion gain transition point for the sensor.

Let’s add a really hamfisted +100 Shadow move to all the images:

ISO 3200
ISO 3200
ISO 100
ISO 100
ISO 200
ISO 200
ISO 400
ISO 400
ISO 800
ISO 800
ISO 1600
ISO 1600

The first thing to notice is how noise-free these images are. The next thing is that the images are pretty ISOless from ISO 3200 through ISO 400, but that once we cross that conversion gain change point, we pick up some noise.
