I set the alarm for an early morning stroll in the hope of catching a sunrise. There were plenty of clouds around which made for a dramatic sky but the sun was not going to play ball. I used a tripod for stability and an ND grad to balance the exposure of the sky. This shot was taken at 17mm at f11 and using hyperfocal focusing. Using the hyperfocal point of the lens is something that I have not really used before, although I have heard of it, so I thought it was about time to give it a go. There is a formula for working out the hyperfocal distance which is…hyperfocal distance = (focal length x focal length) / (circle of confusion x f-stop)
The circle of confusion is commonly 0.02 for a full frame dSLR and 0.03 for a 1.6 corp sensor typically found on a canon crop dSLR. Anyway, I didn’t sit down and work out my hyperfocal point for this photograph; I simply downloaded a free Android app called hyperfocal pro. This took away all of the pain of the math and let me enjoy my photography! By the way, if you want to read up about the circle of confusion there is plenty about it on the internet but it is quite technical and at times, confusing!
