Hello my friend thank you very much for the comment and the upvote. I have manny photos collections I have been taking for more than 20 years now I will keep posting more of them. About the watermarks there are different ways to make with different software and apps but in this case I use and recommend you also to use Adobe lightroom app is freemium and in the export section it offers you to automatically add the watermark you can use text or images as a logo and change text font types, color, size and opacity. Basically the watermark is a text layer over the image layer. Is very easy to make I will make a post in detail explaining how to do. So follow me that way you won't miss any of my contents.
