took these two photos, but changed settings... one is ok, the other not so.. im trying to learn to use manual more, although I did leave iso on auto.. the one that is not so sharp and has noise( I think), is that because the iso is much higher ?.. is it better to have iso as low as possible ?.. the only change I made was shutter speed, which changed iso.. any advice will be appreciated as I am still a work in progress... thanks...
You don't state your ISO settings nor your aperture and shutter speed settings which may make our responses somewhat of a guess. Also stating your camera name and model and lens used may have further helped in our critiquing your photos.
ISO was high? Why? This is a daylight shot. ISO of 100 or 200 should have been more than sufficient.
As for shutter speed controlling ISO? Maybe in shutter priority mode but not in manual mode.
As for ISO, in almost all photographic situations it is best to use the lowest possible ISO to minimize noise (grain). Sometimes this can not be done mainly because of the lack of lighting.
Go back to your camera's manual and consider purchasing Bryan Peterson's "Understanding Exposure." It cost about $26.00 and is carried by most book sellers and can be ordered on line. It's well worth owning.
That book will further expand your knowledge of the photographic triangle; aperture, shutter speed and ISO.
I've been photographing well over forty years, sometimes getting paid handsomely and I still make some mistakes.
I've owned "Understanding Photography" for a little over two years and wish I had had it a long time ago. Although I've accumulated several photographic books throughout the decades, this one so far is my best go to book.
Several other UHH-ers also recommend this book.
One of the things which digital photography does is spoils us. We can take many, many pictures just to get that one good photo.
Where as in film days we learned how to get the best shot while taking one, two or three photos so as not wasting film. So we learned, we studied, we talked to others and we read. Now most of us film guys who are doing digital don't need to take many shots just to get that one best photo.
However you have an advantage. Get that book and keep taking pictures. By the way, nice shots.
