OK, after a month in which my NAS drive with 65,000 images died and had to be replaced, I'm back on the case.
As a camera club member I have been used to cropping images during post processing to any size that removes distracting elements and helps simplify the composition concentrating the attention to what I am trying to show the viewer. We run 5 print competitions per annum, so apertures in the mount can be cut to suit any aspect ratio that I end up with. My first take away is that I will bear in mind the 16:9 aspect ratio and where possible produce a virtual copy in LR that is more slideshow friendly!
I am currently exploring what the various options look like and adding them all into a slideshow so that I can compare them and try to understand what works and what doesn't. When cropping an image that was intended to be viewed in a 9:16 aspect ratio you get something entirely different if cropped to 16:9. I am exporting the slides and pasting them into an annotated document so that I can refer back to this process and the various options, in the future, hopefully at some point I will become familiar enough to just intuitively know without having to check my notes. (It's taken me 5 years to understand the basics of LR & PS already).
I am also at the point where not knowing the terminology means I struggle to search for the help I am seeking. For example I have seen a Barry Beckham video in which he adds the same portrait image of a dog rotated and overlaid to fill the frame, but not knowing what the technique is called means I cannot find it again.
Barry's website is full of valuable links, but at the moment they are inaccessible due to me not knowing what I should be looking for or where. I have to say that I had almost the same problem with LR & PS albeit using the Adobe classroom in a book indexes).
Even when using the search term Ken Burns with the "PTE AV Studio 11" folder highlighted in Yellow, yielded "No results". I must be getting something wrong somewhere
My question is: Is there an index somewhere that can assist me to locate the help files and videos that will get me moving on my journey?
