Thank you! Yes I do like the way that looks! I will recommend to my wife that she add a 'watermark' as opposed to just a signature. Thank you again!
Well...Woody really gets the credit for calling the 16:9 ratio!
Whether you use a signature or watermark is entirely up to your own discretion. I think Mike's comment had to do with where the signature was placed. Usually they are located closer to a bottom corner. Some people might post a watermark/signature right across the subject. Usually those might be for clients who are proofing images so they don't simply just keep them.
Of course, I've heard there are other ways to share images without doing that. One of our esteemed forum members, Don, passed recently. He had someone set up his web site so the images couldn't be downloaded. There is a discussion here on the forum somewhere that tells about it. Unfortunately since he is no longer with us, we can't find out any details other than what is already posted.
But your wife can use either a signature or watermark. I make mine as an adjustment brush. When I apply it, it creates a new layer just for my watermark. If I don't like the location, I can use the move tool to place it elsewhere.
Anyway...getting back to the 16:9 crop. Depending upon which post processing software you use, many offer preset crop ratios such as 5:7, 4:5, 2:3, and 16:9. Check to see if 16:9 is available on your computer. Nice image by the way!
