It is the most famous and widely used image format in the world.<\/p>\n<p data-path-to-node=\"4\">But what does it mean exactly, and why is it so widespread? Let's take a look together without any technical jargon.<\/p>\n<h3 data-path-to-node=\"6\">The Pie Metaphor: JPG vs. RAW<\/h3>\n<p data-path-to-node=\"7\">To understand what JPG is, let's imagine your camera is a chef:<\/p>\n<ul data-path-to-node=\"8\">\n<li>\n<p data-path-to-node=\"8,0,0\"><b data-path-to-node=\"8,0,0\" data-index-in-node=\"0\">The RAW file:<\/b> It's like having all the fresh ingredients for baking a cake on the table (flour, eggs, sugar). It takes time to be \u201ccooked\u201d (modified on the computer), but it gives you full control over the final result.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"8,1,0\"><b data-path-to-node=\"8,1,0\" data-index-in-node=\"0\">The JPG file:<\/b> It&#x27;s the ready-made cake\u2014baked and decorated by the camera. It&#x27;s ready to eat (or share) right away, but you can&#x27;t change the ingredients anymore.<\/p>\n<\/li>\n<\/ul>\n<p data-path-to-node=\"9\">When you shoot in JPG, the camera captures the scene&#x27;s details, automatically adjusts the colors, contrast, and sharpness, and delivers a finished image.<\/p>\n<h3 data-path-to-node=\"11\">The great advantages of JPG<\/h3>\n<p data-path-to-node=\"12\">Why does almost everyone use JPG? There are three main reasons:<\/p>\n<ol start=\"1\" data-path-to-node=\"13\">\n<li>\n<p data-path-to-node=\"13,0,0\"><b data-path-to-node=\"13,0,0\" data-index-in-node=\"0\">Lightweight (Space Saved):<\/b> JPG uses a &quot;compression&quot; system. It removes details that the human eye has trouble noticing, making the file very small. This means you can save thousands of photos on a memory card.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"13,1,0\"><b data-path-to-node=\"13,1,0\" data-index-in-node=\"0\">Universal compatibility:<\/b> A JPG file opens everywhere. Whether you send it on WhatsApp, upload it to Instagram, open it on Grandma's computer, or print it at the photographer's, it will always work without a problem.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"13,2,0\"><b data-path-to-node=\"13,2,0\" data-index-in-node=\"0\">Ready to use:<\/b> You don't have to spend hours editing the photo on the computer. The shot is already optimized and ready to be shown to friends and family.<\/p>\n<\/li>\n<\/ol>\n<h3 data-path-to-node=\"15\">There's a \u201cbut\u201d: The limitations of JPG<\/h3>\n<p data-path-to-node=\"16\">All that glitters is not gold. The convenience of JPG comes at a small cost:<\/p>\n<ul data-path-to-node=\"17\">\n<li>\n<p data-path-to-node=\"17,0,0\"><b data-path-to-node=\"17,0,0\" data-index-in-node=\"0\">Loss of quality due to the changes:<\/b> If you try to adjust a JPG photo that is too dark or too light using photo-editing software, you&#x27;ll immediately notice some &quot;distortion&quot; (digital noise or strange colors). The information lost during compression cannot be recovered.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"17,1,0\"><b data-path-to-node=\"17,1,0\" data-index-in-node=\"0\">Less flexibility:<\/b> Choices such as the <i data-path-to-node=\"17,1,0\" data-index-in-node=\"34\">white balance<\/i> (i.e., whether the photo has a blue or yellow cast) are \u201cembedded\u201d in the file at the moment the photo is taken.<\/p>\n<\/li>\n<\/ul>\n<h3 data-path-to-node=\"19\">When is it beneficial to use JPG?<\/h3>\n<p data-path-to-node=\"20\">JPG is the ideal choice for most everyday situations:<\/p>\n<ul data-path-to-node=\"21\">\n<li>\n<p data-path-to-node=\"21,0,0\">Photos of everyday life, vacations, and family celebrations.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"21,1,0\">Images intended exclusively for social media or chat apps.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"21,2,0\">When you have little space on your memory card or phone.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"21,3,0\">If you want to take a lot of photos in quick succession (for example, during a sporting event).<\/p>\n<\/li>\n<\/ul>\n<h3 data-path-to-node=\"22\">In summary<\/h3>\n<p data-path-to-node=\"23\">The <b data-path-to-node=\"23\" data-index-in-node=\"3\">JPG<\/b> It&#x27;s the best friend of anyone who wants to take photos without a care in the world: lightweight, practical, and versatile. If your goal is to capture a beautiful moment and share it right away, JPG is exactly what you need!<\/p>","protected":false},"excerpt":{"rendered":"<p>Se hai mai scattato una foto con il tuo smartphone o con una fotocamera digitale, hai quasi sicuramente a che [&hellip;]<\/p>\n","protected":false},"author":10,"featured_media":22725,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[764],"tags":[],"class_list":["post-22724","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-mondoarteefotografia"],"_links":{"self":[{"href":"https:\/\/photoworld.it\/en\/wp-json\/wp\/v2\/posts\/22724","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/photoworld.it\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/photoworld.it\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/photoworld.it\/en\/wp-json\/wp\/v2\/users\/10"}],"replies":[{"embeddable":true,"href":"https:\/\/photoworld.it\/en\/wp-json\/wp\/v2\/comments?post=22724"}],"version-history":[{"count":1,"href":"https:\/\/photoworld.it\/en\/wp-json\/wp\/v2\/posts\/22724\/revisions"}],"predecessor-version":[{"id":22726,"href":"https:\/\/photoworld.it\/en\/wp-json\/wp\/v2\/posts\/22724\/revisions\/22726"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/photoworld.it\/en\/wp-json\/wp\/v2\/media\/22725"}],"wp:attachment":[{"href":"https:\/\/photoworld.it\/en\/wp-json\/wp\/v2\/media?parent=22724"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/photoworld.it\/en\/wp-json\/wp\/v2\/categories?post=22724"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/photoworld.it\/en\/wp-json\/wp\/v2\/tags?post=22724"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
