This picture it is a bit of a mystery to me for a couple of months ago I was testing my new Sigma lens 70 - 300 mm APO DG and the sun was quickly going down and hiding behind the tall buildings surrounding Brisbane's Botanical Gardens in the city. Somehow I took the picture with the settings below and it still managed to come out.



I took the picture with a Canon EOS 30D in RAW format in a tripod. Other information: Sigma lens 70 - 300 mm with a Focal Length 300 mm. Aperture F/13, Exposure 1/3200 sec. using Aperture Priority. ISO-1250. I sharpened the picture, re-sized it, and converted it to JPG format using Photoshop.

I guess it shows Canons superior noise capabilities .. @ iso 1250..

"Sunny f/16 rule" says that with an ISO of 1250, you'd shoot in full Sun with 1/1250s and f/16. With the camera on f/11 you'd go for 1/2500s. So in theory you are underexposed by about 1/3 of a stop. Being a white flower would make that somewhat easier.

But then when you consider the Sun was going down... I think I heard somewhere that Canon's meter can overexpose a little.


Anyway, it is a good sharp image.
