processing&lt;/a&gt;:&lt;/p&gt;

    &lt;div style="flex: 1;"&gt;
        Before:&lt;br&gt;
       &lt;img alt="A grayscale image of a Christmas tree with very
       limited dynamic range." src="https://mahurin.us/robtasm/posts/2026/01/02/a-thousand-mumbled-words/assets/xmas1.jpg"&gt;
    &lt;/div&gt;
    &lt;div style="flex: 1;"&gt;
        After:&lt;br&gt;
        &lt;img alt="The same data, processed automatically by camera to
        make a pretty nice photo." src="https://mahurin.us/robtasm/posts/2026/01/02/a-thousand-mumbled-words/assets/xmas0.jpg"&gt;
    &lt;/div&gt;
&lt;/div&gt;
&lt;p&gt;Far from being an “unedited” photo: there’s a huge amount of math
that’s gone into making an image that nicely represents what the
subject looks like in person. […] There’s nothing wrong with
tweaking the image when the automated algorithms make the wrong
call.&lt;/p&gt;
&lt;/blockquote&gt;
