This is my first time ever shooting with film so I'm not sure what I'm doing wrong. Many of the photos in the roll are super crisp and clear but some have this kind of foggy haze, especially all the landscape photos I took. I attached a couple beach photos taken on the same overcast day probably 15 mins apart, also a picture of the beach on a clear very sunny day and they were all foggy.
The negatives of the photos are below.
Some other examples are these two photos of flowers I tried to take.
