Is using Photoshop Cheating?

Is Photoshop really cheating when it comes to photography ethics? I keep coming across people accusing and being accused of "cheating" an image by using the wonders of Adobe Photoshop, and that their work isn't really photography at all, but another form of art altogether. First of all, my opinion is "so what"? What does it really matter how the artist or photographer got to the finished image? As long as it is thought provoking and pleasing to the eye, and as long as it can be used in any necessary context for publication if so desired, do we really need to know how and/or why it was done? Sure, a hard-core, original style photographer would say that the true image should be made at the time of capture, as the event happens and that any later enhancements are misleading to the end viewer. To that I say "poppycock"! For me, the only true and real photography is that of photojournalism, and as I am sure you will agree, photojournalism should not and must not be tampered with for monetary gain or to purposely mislead the viewer. Some of the most awesome and thought provoking photojournalistic images have stayed in my mind since I was at primary school. One image that springs to mind is that of a young, naked Vietnamese girl having just been napalmed during the war, running down a road. There would be no reason and no point to further enhance this image, it tells its own horrific story as it is. When it comes to photographs as an art form, I guess photographers have been "misleading" people since the first "Daguerreotypes" were being made. The famous photo of the Cottingley Fairies held true for years until being finally exposed as a fake. Does it matter that it was a fake? The authors have created one of the most famous images and talked about legends for nearly a century that will be discussed for centuries more no doubt! What about when an interior photographer like myself moves items of furniture in a house, or adds a bowl of fruit to a room to enhance the image? What about when we add make up to a model before a shoot or re-arrange a wedding dress? None of these images tell the story of a scene as it was when we arrived at it. All the alterations were made manually to make the image more pleasing. So what is the difference between doing it before the shoot at the scene, or after the shoot in Photoshop? What is the difference between pulling an obtrusive branch out of your way for that perfect landscape or simply removing it later on your PC. Why do wedding photographers carry clothes pegs to pin back the dress for some formal shots? Is that cheating? I am sure also, that when Turner or Constable made their beautiful paintings, that maybe another ship was added here, or an annoying, unwanted bush was removed there. In fact it has been suggested that the "Masters" used optics to project the model
