With so many changes and improvements, I had been considering creating a Digital Basics III PDF. Recently, I realized that creating a series of videos would be a lot simpler and would make learning a lot simpler for most folks. In addition, videos will allow me to delve more deeply into the fine points of using the new (and previously used) Photoshop tools. Each video will include two complete image optimizations, from soups to nuts.<\/p>\n<p>Additional details soon. <\/p>\n<h3>Mini IPT or In-the-Field DeSoto Sessions this Week<\/h3>\n<p>Meet me at North Beach in Fort DeSoto on Wednesday morning (4 OCT). Share my Gulfport AirBnb for one or two nights (or not), and enjoy as many as five in-the-field sessions. I will be heading home after the morning session on Friday 6 OCT. The weather is looking excellent. I am offering either of these opportunities for a ridiculously low getting-to-know-you price, too low to mention here. Please remember that you only live once. For details, shoot me an <a href=\"mailto:samandmayasgrandpa@att.net\">e-mail<\/a> or call or text me on my cell phone at 863-221-2372. A working lunch with image review and Photoshop lessons is optional. I can tailor things just for you.<\/p>\n<h2><strong>Canon 500mm f\/4L IS USM Super-telephoto Lens (the \u201cOld Five\u201d)<\/strong><\/h2>\n<p><font color=\"red\"><strong>$200.00 Price Drop on 10\/2\/2023<\/strong><\/font><\/p>\n<p>Roy Holden is offering a Canon EF 500mm f\/4L IS USM super-telephoto lens (the \u201cold five\u201d) in excellent plus condition for a BAA record low $1799.00 (was $1999.000). The sale includes the front leather lens cover, the lens trunk, the rear lens cap, and insured ground shipping via major courier to lower 48 US addresses only. Your item will not ship until your check clears unless other arrangements are made.<\/p>\n<p>Please contact Roy via <a href=\"mailto:roy.57hold@gmail.com\">e-mail<\/a>.<\/p>\n<p><em>The 500mm f\/4 lenses have been the world\u2019s most popular telephoto lenses for birds, nature, wildlife, and sports for many decades. I owned and used and loved my \u201cold five\u201d for many years. If you use Canon and don\u2019t have the cash for a 500 II, and can handle the additional 1 1\/2 pounds, then this is your best super-telephoto lens option. Most everyone can produce sharp images with this lens and a 1.4X TC. Folks with good to excellent sharpness techniques can do the same with a 2X TC. Used 500mm II lenses are selling for as much as $7,018.95. I was surprised to learn that they are no longer in production as it was one of my favorite Canon super telephoto lenses. Used copies are selling for from $2,899.95 to $3,349.95 right now on B&#038;H. This lens will work perfectly on your dSLR bodies and\/or with the Canon Mount Adapter EF-EOS R on all Canon mirrorless bodies.<\/em> artie  <\/p>\n<h3>What&#8217;s Up?<\/h3>\n<p>Early on Sunday morning, I headed west on SR 60. There were no Cattle Egrets as there had been the day before. And the herd of black cows that had been next to the fence line the day before had moved about a mile to the north, far out of photographic range. Thus, there were no Cattle Egrets standing on the backs of black cows \ud83d\ude41 So, I drove home and photographed Morning Glory blossoms in my butterfly garden. <\/p>\n<p>Today is Monday 2 October. I will spend a good part of the day getting ready to head over to Fort DeSoto on Tuesday afternoon. Wherever you are an whatever you are doing, I hope that you too have a great day. <\/p>\n<p>Please remember to use the B&#038;H and Amazon links that are found on most blog pages and to use the BIRDSASART discount code at checkout when purchasing your new gear from Bedfords to get 3% back on your credit card and enjoy free second-day air FedEx.
