I have discovered that pale yellow flowers are hard to photograph and this is probably the best I can do. I hope you have a well-adjusted monitor!
Can you see the light in this photo? Look at the softly highlighted stems of these flowers and you will. I don't think I saw this when I took the photo. As I've said before, there are often things I see on the computer that aren't really all that visible through the view finder.
