<p>[QUOTE=&quot;ola402, post: 13103140, member: 182&quot;]Last entry:&nbsp; discovered that I need a 365nm flashlight to detect the manganese in EAPG.&nbsp; I have a 395nm blacklight which works on uranium glass but not&nbsp; manganese.&nbsp; I will order a new blacklight, who knew?&nbsp; Probably everyone but me, the flashlights all looked the same at Home Depot. </p><p><br /></p><p>And I could write a book about what I learned about my new iMac computer.&nbsp; I spent the weekend finding out how to convert image .heic files (Apple&#039;s new format) to jpeg while at the same time compressing them (convenient for the board).&nbsp; This is for photos taken on my iPhone which I also learned I could set it to take only jpeg format.&nbsp; I don&#039;t think I&#039;ll ever be able to use my old Fuji camera any more unless I use the old iMac.&nbsp; Sad, I love that camera.&nbsp; All weekend, I would google something and Surprise!&nbsp; It changed without consulting me.&nbsp; But at least I got answers after I figured out how to ask them.&nbsp; I&#039;m officially old and out of it.[/QUOTE]</p><p><br /></p>
