why would you want to crop when you crop it within the frame itself.
Unless of course you are creating a series which needs special cropping method. Photography is a form of art by itself. Agree with student, it's not for joy or satisfaction. In fact you should be satisfied from your own point of view and not others when you crop an image.
Again cropping your image COULD be for a series of photos.
I agreed with CK that one cannot be always 100% right on shooting. I found there is no harm done if one were to crop slightly or no more then 20% of the original and must state that in the picture posted.
Otherwise, it would mislead viewers into thinking that was the way the picture was taken. I have seen pictures being cropped severely and appeared relatively fine on screen viewing. However, when they got it printed on 8R size, it can be thrown into the drain. This normally occured in nature shots using DSLR and when condition was not ideal during the time of shooting.
i guess theres some confusion here cos there are different types of photographers here in the thread....if you shoot landscapes, architecture, macro, protraiture etc and you find that you still need to crop constantly...then its time you found a new hobby. but if you are more into sports (where capturing the peak of the action is more important than perfect framing), reportage and social documentary, then i guess some cropping may be necessary when its more important to get the shot than no shot at all...
Your viewfinder, unless you are using a pro body, is often not 100%. there is nothing wrong to crop off the additional 5% to 8% to readjust the image. That is just to restrict to a 3:2 crop.
Personally there is nothing wrong with cropping. the important thing is you are aware of what you are shooting or trying to achieve initially rather than try to salvage photos later. Medium format users have been known to crop their photos to achieve panoramics.
If you are uncomfortable with cropping... don crop.. it is your personal choice.
There is a lot to say for using the entire real estate in your sensor (CCD/CMOS/Film). The images are sharper (less enlargement) and tonality better.
But I have absolutely no problem with cropping when the result is a stronger image. Sometimes at the time of shooting, I think that what I wanted was just. But when I study the image, I find that there can be many unnecessary distractions, so I crop. A matter of the eye. Hopefully, with experience, the need to crop will be reduced.
