ISO 500??

[*Babs]

I've just noticed that the EXIF data for one of my recent flower shots shows an ISO of 500

My camera settings for ISO (Canon 40D) are 100, 200, 400, 800, 1600 and H. Where did this 500 come from?!

If it was on auto iso or a program mode it can select 1/3 stops of iso.

Ahh! Thank you! I probably had it on Auto ISO (on Av mode) as I was shooting in the sunset light in varying sunlit and shade conditions.

I just saw it and wondered where it'd come from! Another thing learnt!
