Some believe street images should not be cropped. They also believe you should shoot with primes only and "use your feet". What happens when that does not do the job? Do you toss the image?
Cropping, whether it is done before or after the initial capture is a part of photography and always has been. Some of the greats of old did, some did not.
EPM2 17mm
This image is a busy (too busy) street scene with no strong focus.
The extra intimacy and impact of this image cropped surprised me.
I do not crop much. I am a bit OCD about straight lines, but often there is not the room to fix every lop sided image.
Also cropped and straightened. The cropping exaggerated the closeness of the pointed finger.
