Pixel editor vs. creator... A completely academic concept. It's all about taking the result of pressing the shutter button and making pictures for useful purposes. Pixel creation or editing is simply transforming data for a purpose.
LOL! The phrase "non destructive" always makes me laugh. I envision people timidly editing -unsure of every editing step (and thus looking to be able to undo it), then saving their edits over their original files (thus destroying the ability to edit the image ever again). Then along comes a "non destructive" workflow to save the day!!!
Nothing a person does to an original photo is destructive providing they save their results in an alternate file! And some people even know how to edit those pixels right the first time!
Wait, for some reason I'm feeling the urge to cross to the dark side... Raw is better! Yes, there are 14 bits instead of 8! I have more control! More is better! Non destructive editing is the cat's meow! I love peeping at pixels (not to mention shooting focus targets)! Wooooohooooo!
Sorry, got going there for a moment.
By the way, I do shoot Raw most of the time. I still sometimes feel guilty about it though.
