This is a pretty normal view. I've been a photographer and videographer since I was about 16, and worked freelance and in magazines all over my country before I got into teaching and IT.
If you read any film theory book, you'll eventually come accross Cahiers du Cinéma and André Bazin, one of the philosophers who most greatly influenced the Nouvelle Vague movement of cinema in France.
He would argue that the second you even point the camera at something, that's when the editing of reality starts. So in the end, what really matters, is the expression you're looking for. So work on that, and worry less about the tools you use to get there.
Many have since tried to challenge this view in various ways, including the Direct Cinema, and Cinema Verité movement, and even up to guys like Lars von Trier with his rather stringent Dogme manifesto. Because when you've mastered all other forms, the only way to challenge yourself is to give yourself artificial limits.
So do you morally have to say no to CG or photoshopping? Absolutely not. It's a tool like any other. You can use it to enhance the experience. And with todays digital cameras, it is often needed to glean the experience you had when watching the subject in real life, kind of like the expressionist painters of yore, who would strive to paint the feeling they had with the subject, rather than illustrate "the truth." Or you can willfully subject yourself to artificial limits, because it's a challenge.
With that said, I think the photos shown here reveals brilliant and inspired creativity with new techology and tools, and in the end, that's what it's about: To make something fantastic out of perhaps untraditional tools, either because it's a challenge, or because you have a grand vision—or both.
Anyway, I hope this gives you some inspiration to pick up your camera (any camera, even the one on your iPhone), and challenge yourself.
All the best!
