Shooting with the 70-200mm f\/4 wide open I was pushed to ISO 12,800 on the 5D3. Pretty crazy if you still have any memory of film days, but plenty usable with only a moderate amount of noise reduction in Lightroom (luminance = 30). Congrats to the graduating students!<\/p>\n<div id=\"attachment_786\" style=\"width: 650px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/philarmitage.net\/blog\/wp-content\/uploads\/2016\/05\/aps_graduation.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-786\" src=\"https:\/\/philarmitage.net\/blog\/wp-content\/uploads\/2016\/05\/aps_graduation-1024x1024.jpg\" alt=\"Celebration a degree\" width=\"640\" height=\"640\" class=\"size-large wp-image-786\" srcset=\"https:\/\/philarmitage.net\/blog\/wp-content\/uploads\/2016\/05\/aps_graduation-1024x1024.jpg 1024w, https:\/\/philarmitage.net\/blog\/wp-content\/uploads\/2016\/05\/aps_graduation-150x150.jpg 150w, https:\/\/philarmitage.net\/blog\/wp-content\/uploads\/2016\/05\/aps_graduation-300x300.jpg 300w, https:\/\/philarmitage.net\/blog\/wp-content\/uploads\/2016\/05\/aps_graduation-768x768.jpg 768w, https:\/\/philarmitage.net\/blog\/wp-content\/uploads\/2016\/05\/aps_graduation.jpg 1280w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><p id=\"caption-attachment-786\" class=\"wp-caption-text\">Celebrating an astronomy degree with a look to the heavens<\/p><\/div>\n<div id=\"attachment_785\" style=\"width: 650px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/philarmitage.net\/blog\/wp-content\/uploads\/2016\/05\/aps_graduation2.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-785\" src=\"https:\/\/philarmitage.net\/blog\/wp-content\/uploads\/2016\/05\/aps_graduation2-1024x640.jpg\" alt=\"Newly minted Ph.D.\" width=\"640\" height=\"400\" class=\"size-large wp-image-785\" srcset=\"https:\/\/philarmitage.net\/blog\/wp-content\/uploads\/2016\/05\/aps_graduation2-1024x640.jpg 1024w, https:\/\/philarmitage.net\/blog\/wp-content\/uploads\/2016\/05\/aps_graduation2-300x188.jpg 300w, https:\/\/philarmitage.net\/blog\/wp-content\/uploads\/2016\/05\/aps_graduation2-768x480.jpg 768w, https:\/\/philarmitage.net\/blog\/wp-content\/uploads\/2016\/05\/aps_graduation2-480x300.jpg 480w, https:\/\/philarmitage.net\/blog\/wp-content\/uploads\/2016\/05\/aps_graduation2.jpg 1280w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><p id=\"caption-attachment-785\" class=\"wp-caption-text\">Newly minted Ph.D.<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>We hold an annual departmental graduation ceremony for our majors and Ph.D. students in Fiske planetarium.
