I don't have any flowers in my yard, but my sister-in-law did and the hotel we spent the weekend did, so after 700 pictures I have narrowed it down. It helps that I took all of them on manual mode and forgot to check my ISO for 42 pictures, so I have 42 completely white pictures of Daffodils on ISO 1600--they looked great in the view finder. After that I did get better at checking my histogram each shot.
I actually narrowed it down to 8 different pictures and had my friends at my Real Life Blog help so I could follow the rules this week.
f/5.6 1/250 175mm ISO 100
Thank you for the challenge and the motivation to get out and shoot!
