The absolute last thing that touched the file was the\u00a0Photokit output sharpener tuned for the ppi of the file.<\/p>\n<p>So if I want richer colors I guess I print at 360 ppi.\u00a0 But is the extra richness worth files twice the size of the 180&#8217;s?\u00a0 I&#8217;m not sure.\u00a0 You have to compare the prints side by side and look pretty closely to see the difference.\u00a0 I doubt a casual observer would notice it.<\/p>\n<p>On the other hand, I like to\u00a0take that extra step to make my photographs the best they can possibly be so it looks like I&#8217;ll standardize on 360 from now on.<\/p>\n<p class=\"bawpvc-ajax-counter\" data-id=\"321\"> (1344)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I print my fine art prints with Image Print, an excellent RIP.\u00a0 And I print on an Epson 4800.\u00a0 Image Print gives you the option of printing at 180 or 360 ppi.\u00a0 I&#8217;ve printed a lot of great looking, rather large\u00a0photographs at 180 ppi.\u00a0 A lot of my friends are shocked.\u00a0 They say I&#8217;m compromising &hellip; <a href=\"https:\/\/ralphnordstromphotography.com\/wordpress\/2009\/01\/19\/180-or-360-dpi\/\" class=\"more-link\">Continue reading<span class=\"screen-reader-text\"> &#8220;180 or 360 ppi?&#8221;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":false,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2},"jetpack_post_was_ever_published":false},"categories":[3,4,6],"tags":[205,91,204],"class_list":["post-321","post","type-post","status-publish","format-standard","hentry","category-articles","category-how-to-articles","category-journal","tag-fine-art-prints","tag-genuine-fractals","tag-image-print"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/p9Nl7-5b","jetpack_likes_enabled":true,"_links":{"self":[{"href":"https:\/\/ralphnordstromphotography.com\/wordpress\/wp-json\/wp\/v2\/posts\/321","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ralphnordstromphotography.com\/wordpress\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ralphnordstromphotography.com\/wordpress\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ralphnordstromphotography.com\/wordpress\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/ralphnordstromphotography.com\/wordpress\/wp-json\/wp\/v2\/comments?post=321"}],"version-history":[{"count":3,"href":"https:\/\/ralphnordstromphotography.com\/wordpress\/wp-json\/wp\/v2\/posts\/321\/revisions"}],"predecessor-version":[{"id":329,"href":"https:\/\/ralphnordstromphotography.com\/wordpress\/wp-json\/wp\/v2\/posts\/321\/revisions\/329"}],"wp:attachment":[{"href":"https:\/\/ralphnordstromphotography.com\/wordpress\/wp-json\/wp\/v2\/media?parent=321"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ralphnordstromphotography.com\/wordpress\/wp-json\/wp\/v2\/categories?post=321"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ralphnordstromphotography.com\/wordpress\/wp-json\/wp\/v2\/tags?post=321"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
