The backlight in the two images from the old blog post were both somewhat muted; this allowed me to work with much less negative ECs and at wider than typical apertures than I would in true blasting highlights situations. Compare this situation with the situation on the Galapagos above&#8230; <\/p>\n<h3>The Answer<\/h3>\n<p>Whenever I am faced with a blasting highlights situation, i.e., when I am shooting directly into the sun and into the specular highlights of said sun off the surface of the water, the first thing that I do is to lower the ISO. Why? Setting a lower than normal ISO will allow you to avoid the really small apertures the might lead to problems. And if you prefer a smoother rather than a more detailed look at the aforementioned specular highlights, it is often mandatory to choose a low ISO so that you can work close to the wide open aperture. Note the shutter speed (1\/5000 sec.) and the aperture (f\/13) in today&#8217;s featured image despite the relatively low ISO (200). <\/p>\n<table>\n<tr>\n<td>\n<p><a href=\"https:\/\/www.birdsasart-blog.com\/baa\/wp-content\/gallery\/general\/laughing-gull-bright-highlights-_36a0112-fort-desoto-county-park-pinellas-fl.jpg\" class='shutterset'><br \/>\n<img decoding=\"async\" class=\"ngg-singlepic ngg-center\" src=\"https:\/\/www.birdsasart-blog.com\/baa\/wp-content\/gallery\/general\/laughing-gull-bright-highlights-_36a0112-fort-desoto-county-park-pinellas-fl.jpg\" alt=\"laughing-gull-bright-highlights-_36a0112-fort-desoto-county-park-pinellas-fl\" title=\"laughing-gull-bright-highlights-_36a0112-fort-desoto-county-park-pinellas-fl\" width=800 \/><\/a>  <\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p>This image was of course also created on the 2015 Fort DeSoto IPT with the <a href=\"https:\/\/www.outdoorphotogear.com\/search.php?search_query=indurogrand&#038;rfsn=132487.5cf37.9906\">Induro<\/a> GIT 304L\/<a href=\"http:\/\/birdsasart-shop.com\/mongoose-action-head\/\">Mongoose M3.6<\/a>-mounted <a href=\"https:\/\/www.bhphotovideo.com\/c\/product\/973129-REG\/canon_5176b002_ef_200_400mm_f_4l_is.html\/BI\/6633\/KBID\/7226\/kw\/CA2004004IS\/DFF\/d10-v2-t1-xCA2004004IS\" target=\"_blank\">Canon EF 200-400mm f\/4L IS USM Lens with Internal 1.4x Extender<\/a> (with the 1.4X TC engaged at 519mm) and the best-ever digital camera body value, the <a href=\"http:\/\/www.bhphotovideo.com\/c\/product\/1081808-REG\/canon_9128b002_eos_7d_mark_ii.html\/BI\/6633\/KBID\/7226\/kw\/CAE7D2\/DFF\/d10-v2-t1-xCAE7D2\" target=\"_blank\">Canon EOS 7D Mark II<\/a>.
