Our next entry is from Linda…
“Both of my pics are of roses. The foliage behind Rose OK is in focus, but not in Rose Oops. I know this has to do with something technical, but am unsure what. Also, in Rose Oops my shadow is in the picture, which I’m sure is not a good thing!
Rose OK has ISO 125, focal length 19 mm, aperture 4.3475, and f4.5.
Rose Oops is ISO 100, focal length 13 mm, aperture 4.34375, and f5.
Is it the focal length that blurs the background in Oops? And is that simply because I’ve moved closer?”
