Hello campers!!!
If you've just joined us, I've decided to re-write the OP to hopefully reduce the number of confused responses - especially if you don't want to read all the posts.
The original, "thinking out loud" post is at the bottom in size 1.....feel free to enlarge it, if you want to read my first, slightly confusing words:
So, what's the point of this thread?
It started out as an idea. It literally just came to me, which is why some early responses were quite negative, because I didn't have a fully formed message....
Now, I do.
Really, this thread should be titled Do you habitually crop heavily in PP? If so, perhaps you're not getting all your gear could offer...
The premise is that we dSLR users can be a lazy bunch. Don't deny it 
And we can then justify our actions until we're blue in the face.
But PROBABLY, the truth is, that *unless we have no other choice in the matter, (which I'll expand on next), the way to NOT get the best from our gear, is to think that cropping a shot in PP is just as good as pre-planning the shot before we press the shutter.
And I'll stick my neck out, and suggest further, that it's an addictive habit best avoided as much as possible.
Before the haters jump in, here are the "no choice in the matter" caveats:
* Want/need to crop to a square/other shaped format? Of course, there's no other solution when using a current EOS camera.
* Re-framing because something else/unexpected catches our eye? Excellent! And how lucky!!!
* Shooting at the extreme of a long lens, which still isn't quite long enough? This could be wildlife, sports, you name it. Sometimes, we simply take what we can.
* Sorting out horizons, doing a tiny trim to get the image "just so", etc? Nothing wrong there, either.
* Trying a new, funky cropped shape for creative purposes? Go for it! I love creativity, and it's nothing to do with my point.
* And I'm not a "straight out of the camera" is the ONLY way, nutjob either!
I'm sure there are a few more caveats, but back to the thread, and the "why"?
Well, just think about it.
If you don't think about your shots BEFORE lifting the camera; if you don't try to make sure the right/best lens from your bag is on your camera; if you don't consider what you're about to shoot, and why; if you don't take even one second to compose your shot through the viewfinder, so that it closely resembles the final image in your mind's eye, why are you using a dSLR with interchangeable lenses?
The Canon EOS system (and the dSLRs from all manufacturers) is remarkable in what it can do. Some things can be done in PP which boggle the eye.
But just making a little bit more effort BEFORE even picking up your camera bag(!), will, I suggest, pay you back a hundred times over.
Happy shooting,
Simon
I've been thinking about this for a while, and decided to do a thread about it. And I was pondering where to put this...
...but it directly affects all digital camera users, so I think here is best.
So, on a regular basis I see threads where various dSLR owners knock other owners. Mostly it's about "technical" stuff like the size of sensors, photodiode density, ISO handling, fps, full-frame versus crop, and suchlike.
All fairly harmless in my opinion because ALL modern cameras are tremendous pieces of kit compared with early dSLRs, and fiddling with them is so much more accessible than film cameras due to instant feedback on the little screen on the back.
But what isn't harmless is our habit of thinking that if we spot any failings, well, we can fix those on the computer with a few deft clicks.
Of course, some areas of post processing enhance images tremendously...but I think one of the main reasons why so many photos we're seeing on the internet irrespective of the camera body/lens used, look really quite ordinary, is because too many people are missing a fundamental skill in photography, exactly because it's so easy to "fix" things in post processing.
And what is that skill?
Framing correctly - which means using your feet, and/or the right focal length lens for each situation.
Why is this, in my humble opinion so fundamental?
1) Because all the arguments about things like depth of field when comparing full-frame to a 1.6 or 1.3 cropped sensor camera are meaningless if the full-frame user habitually crops, but the cropped sensor user frames correctly.
2) Arguing that primes are better than zooms (or vice-versa!!!) is daft if either "group" habitually crop their images on the computer.
3) Complaining that a bird-in-flight shot looks too fuzzy is pointless if it's a 75% cropped image, shot with a 250mm lens when in fact you needed a 600mm lens.
4) "Wow! Your camera takes such noisy photos at ISO3200...it's terrible at 100% on screen!"
I could go on, but I think you get my point.
Frame correctly...don't crop.
Frame correctly.....don't crop!
FRAME CORRECTLY.....DON'T CROP!!!!!!!
Looking at the above examples in a little more detail:
In #1, the depth of field effect requires foreground and background. If the photographer crops too much, those two vital parts of the image are lost/reduced.
In #2, moving your feet/choosing the right lens (if a prime) or the right focal length (if a zoom) will maximise what the lens can do, irrespective of whether it's a prime or zoom on the camera. And knowing when to use either beats cropping on the computer hands-down.
Iin case #3, shooting birds-in-flight is very difficult. It's not "meant" to be easy, simply because you've bought a dSLR. Some realms of photography will take years of practice (and a lot of money!) for anyone to to have even a shot at becoming top of class.
And regarding noise? Looking at images on-screen at 100% and then picking fault should, IMO, result in a 25,000 volt electric shock going directly through the keyboard of the offender, because nobody in their right mind should crop to 100%, thus nobody is going to see such a photo!!!
Well, Missus Skygod is saying it's time for bed, so I'll leave this open for discussion, but in my film days, I always framed properly before even thinking of pressing the shutter button....
.....and I think we'd see a LOT LESS DROSS on the 'net if more digital camera users did the same.
btw, straightening horizons or trimming a slither to attain perfect balance is not what my advice is concerned with.
Cheers for now,
Simon
maybe that is true.... but that is still a ridiculous comment. Or any random complaint that the photog couldn't possibly control in a million years.The point is not everyone can shoot in a studio where all the variables can be controlled. In fact not all of us
