In the film world the image plane is the film itself. In today&#8217;s digital photography world the image plane is the digital sensor. There are many <a href=\"https:\/\/en.wikipedia.org\/wiki\/Image_sensor\" target=\"_blank\" rel=\"noopener\">sensors<\/a> and\u00a0<a href=\"https:\/\/en.wikipedia.org\/wiki\/Full-frame_digital_SLR\" target=\"_blank\" rel=\"noopener\">sensor sizes<\/a> but we will leave that topic for another day.<\/p>\n<p>If a subject of length X results in\u00a0an image of length Y in the image plane then the magnification is defined to be Y\/X. So, if we have a subject that is 10mm in length and it has a length of 10mm on the image plane then the magnification is 10\/10=1x. If the length of the subject on the image plane is 20mm then the calculation would be 20\/10=2x.\u00a0Not all lenses can capture this type of image. \u00a0You will need a &#8220;Macro Lens&#8221; in order to capture &#8220;life-size&#8221; images (1x) on your image plane. \u00a0In addition, capturing magnifications higher than 1x requires even more sophisticated setups and post-processing techniques.<\/p>\n<p>The\u00a0<a href=\"https:\/\/en.wikipedia.org\/wiki\/Diptych\" target=\"_blank\" rel=\"noopener\">Diptych<\/a> below of a pencil and pencil tip was taken with a &#8220;<a href=\"https:\/\/en.wikipedia.org\/wiki\/Full-frame_digital_SLR\" target=\"_blank\" rel=\"noopener\">full frame sensor<\/a>&#8221; camera (image plane measures 36mm x 24\u00a0mm). Its image plane size is equal to an old 35mm film frame, thus the name. The thickness of the pencil is about 7mm and it measures 7mm on the image plane so its magnification is 1x. The image of the pencil tip measures about 5mm high in real life and it measures about 27mm on the image plane. \u00a0So, its magnification is 5x.<\/p>\n<figure id=\"attachment_5076\" aria-describedby=\"caption-attachment-5076\" style=\"width: 1500px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/tkahler.com\/blog\/wp-content\/uploads\/2015\/11\/2015-11-21-Pencil.jpg\"><img fetchpriority=\"high\" decoding=\"async\" data-attachment-id=\"5076\" data-permalink=\"https:\/\/tkahler.com\/blog\/2015\/11\/magnification\/pencil-magnification\/\" data-orig-file=\"https:\/\/tkahler.com\/blog\/wp-content\/uploads\/2015\/11\/2015-11-21-Pencil.jpg\" data-orig-size=\"1500,1225\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;6.3&quot;,&quot;credit&quot;:&quot;Terry B.
