Read on digital photography about adjusting ISO and shutter speed.
But how how adjusting 2 affect the turn out of the photo?
For instance, if you want to change the lighting effect of the picture, you can just change idea the ISO or shutter speed (for sceneries) correct? is there a need to adjust both?
there's a sentence in it also úse the long end of your zoom for tightly cropped images but keep your eye on the ISO to ensure you're getting fast enough shutter speeds to avoid shake' <-- ISO affects shutter speed?
and with regards to aperture...
for having a large aperture or small aperture soften the background?
could really use some help
