I went to a High School football game last Friday and decided to Play with the D800. It is one way I explore the capabilities of the camera plus educate myself. I am not a professional photographer nor am I new to photography having used Nikon F5 film camera and a Nikon D80 when I first started using a Digital (selected so I could use my existing lenses). In August I bought the D800. I have loved it and had no real issues except my sensor getting dirty (oil maybe?).
Anyway, while at the game on Friday, I was not able to get the purple uniforms of the team to render as purple. I tried different White Balance settings thinking it might be the stadium lights but couldn't see a noticeable difference in the uniform colors. I did NOT use a custom White Balance since I wasn't sure what temp to set nor did I have a good image to shoot to create a custom.
