The camera

Ofcourse it is important, the camera, it is the tool you need
to get the picture that you see already in your mind. But what
about the quality? The picture above is taken with an
iPhone 11. I know that is a good phone, but I had a picture
taken with a Samsung S8, printed on a canvas of 100 x 80. First
I had in photoshop the pixels doubled and then sharpened it. It
looked great anyway.
So there is no need to blame your camera if you don't get a
good picture. Mostly the camera does alright when it is on
auto, but there are circumstances when it does not work so
well. For instance in snow: your picture will turn out grey
instead of white. But... that can always be fixed on the
computer later on when you photograph in RAW.
I use a Nikon D7100 and used to have a D750. It also could have
been Canons. But in the time, way back, that I chose, I found
the Nikon sturdier than the Canon, that was more plastic. Later
I DID buy a Canon for that reason: it was light and easy to
bring with you. I disliked however to have to adapt to the
other camera all the time and I did not want to buy two sets of
lenses. So I stuck with Nikon because of my gear I bought
sofar.
If I had to chose again, I would have gone with Canon. I like
their service far better than that of Nikon, but that is
personal. Someone else might have the opposite
experience.
Besides those mentioned I now also use a Samsung S21 that has
three camera's: wide, standard and tele. With that I take some
great pictures too, but the resolution is a lot less of course.
