In this article, we&rsquo;ll focus on aligning a stack of images. Aligning a stack of images can be useful for achieving several results, such as:</p> <ul> <li>bracketed exposures to make an HDR or fused exposure (using enfuse/enblend), or manually blending the images together in an image editor</li> <li>photographs taken at different focal distances to extend the depth of field, which can be very useful when taking macros</li> <li>photographs taken over a period of time to make a time-lapse movie</li> </ul> <p>For the example images included with this tutorial, the <em>focal length</em> is <strong>12mm</strong> and the <em>focal length multiplier</em> is <strong>1</strong>. A big thank you to <a href="https://discuss.pixls.us/users/isaac/activity" target="_blank" rel="noopener">@isaac</a> for providing these images.</p>
