Before the days of digital cameras, all photographic film was categorized with an ISO rating.  Digital cameras have an adjustable ISO.  Increasing digital ISO is primarily a matter of increasing the gain of the electronics signal.  As with most electronics, gain increases not just the signal but also signal noise (stuff you don&#8217;t want).  However, many digital cameras today have excellent signal-to-noise ratio.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the days of film cameras, photographers might &#8220;push process&#8221; film to achieve higher ISO.  ISO 400 was commonly pushed to ISO 800; that&#8217;s a difference of 1 f-stop. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Today, using digital cameras, 1-stop is child&#8217;s play.  Digital cameras can provide 6 f-stops or more &#8230;. ISO 51,200 or better.  The results can be cleaner (less noise) than the old ISO 400 film pushed to 800.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I shot the image here at ISO 5000 &#8230; that was ten years ago.  <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"731\" height=\"1024\" src=\"https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2024\/07\/MAFair-2028-731x1024.jpg\" alt=\"\" class=\"wp-image-1474\" srcset=\"https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2024\/07\/MAFair-2028-731x1024.jpg 731w, https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2024\/07\/MAFair-2028-243x340.jpg 243w, https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2024\/07\/MAFair-2028-768x1075.jpg 768w, https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2024\/07\/MAFair-2028.jpg 857w\" sizes=\"auto, (max-width: 731px) 100vw, 731px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"> (Intonition Band, at night under a tent at Fraklin County Fair)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>ISO is a property of recording photography; it represents sensitivity to capture light.
