I'm a 550D user who has just yesterday ordered a 7D. I've never even looked through the viewfinder on a FF camera, let alone held one.
I do know my way around my camera, but on these boards I keep hearing people talking about Dynamic Range when comparing cameras or making wish lists of improvements.
Can somebody please point towards a good explanation of DR and also comparisons between similar cameras (e.g. D800 and 5D M2/3) so I can understand it better and how it impacts me? Also any explanation of camera IQ would be helpful.
For decades photographers have pursued higher and higher DR in camera's since the original daguerreotype. How much have we improved? Eh, Its hard to say in camera tech.
In-out camera technique such as filters, timing, scouting, HDR (if you like that sorta thing), you can can easily photograph stuff that's far, far beyond anything a bare sensor can capture. Like 20 Stops.
So if you want better DR, Work on your technique to achieve so.
