Cool. I downloaded an app as most of my pics are currently taken with my phone. I don't take really great or sellable pictures, but agree that it is important to establish ownership.
Do you have any experience using a pseudonym? I'd rather not use my real name. I did a quick Google search and I see that it can be done, but I wanted to check if you have any lessons learned.
No experience there, I'm afraid. I have always used my real name. I used to use the tag line "Artist With A Camera" and still do sometimes, but in recent years have noticed that someone copyrighted its use as a name. I guess that's what you have to watch out for. I remember a few years back when a Scottish hamburger cafe owner used even his real name McDonald's and was sued by McDonald's. There was a huge uproar in Scotland at the time, but can't remember the outcome now!
