There are many different photo editing programs that you can use to aid you in creating that perfect image. Paint shop is one of the more lesser-known programs. It's great for just starting out. But the main source for most images is Photo Shop. There is lots of photo shop software out there, for many different specific uses.
There are endless possibilities for what you can create. Abstract images, skylines, artistic, cultural. Or even maybe just some cat wallpapers. Personally, I prefer the minimalist approach. Simple, yet effective enough to get your point across.
Creating images is also a great way to gain some income, for those that are skilled enough. Go with some classic images, and you might find yourself with some fine art printing, or perhaps some vinyl banners. Banner advertising is always a great way to attract attention to people.
Perhaps I will share some of my work in the future!
So, what about you? Are you a newbie when it comes to Photo shopping? Have you mastered every detail of it? Or are you somewhere in the middle?
