A sun compass. If you have not got one of these, then I can really recommend them. I use a piece of software at home called The Photographers Ephemeris. It uses the Google Maps API, and allows you to see what time and direction the sun will be place on the surface of the earth. (As long as Google covers it of course). You can find it here, it really is very good. But what happens when you are out somewhere and you wonder where the sun will come up tomorrow morning? Just whip out your sun compass, align the arrow with north and Ta daa, it tells you.
Anyway, they ain’t paying me, so that’s all they get..lol..
Lesson learnt from taking this shot: Always make sure items for macro shots are spotless before shooting. The light was just right when I took this, so 45 minutes of healing brush, got it to where it is now. Not brilliant, but believe me, you should have seen it before. I never new a spec of dust could cast a shadow.
