Oh, yeah, read the manual.
I have a new book, which I have not yet read. But even glancing through it, I got some help. The automatic mode on my camera is so good that I sometimes forget about all the adjustable features. Simple tips like read the camera manual and adjust the white balance were helpful when I was having trouble with mitten color.
My neighbor, Barbara, has two adorable Springer Spaniel puppies who chewed up a pair of Ambroso mittens I gave her for Christmas, so I made her another pair, this time with a simpler design.
