Re: Impact of Noise and DoF on JPG File Size

JPEG file sizes are very sensitive to the JPEG quality setting, but also to the amount of fine detail in the file.

This image has a file size of 5.1MB at 91% quality setting because it has lots of fine detail.

Original image at 91% JPEG quality is 5.1MB

If I apply a gaussian blur to the image (radius 2.5), then the image size drops to 2.0MB.

Blurred image at 91% JPEG quality is 2.0MB

Original image at 34% JPEG quality is 1.9MB
