Yesterday, I posted a Pic of Tata Kite at http://www.theautomotiveindia.com/fo...tml#post441659
. It was a cropped image and the EXIF was not there, as it was for a diff thread & diff need. How the image retains so much detail is explained here. First the circumstances:
The test mule was doing may be 70-ish speeds and 10-15 feet ahead of me, I was around 80kph, and the Auto was about 30-40 feet ahead (looking at the Pic). The < 500g Cam+Lens Combo was hanging down my neck (Ahhh ... Mirrorless Cams). I spotted the mule, removed the Lens Cap with my left hand, powered the Cam ON and framed the shot blindly (with right hand). My Daughter helped me to frame the shot and I clicked (I would've preferred the mule at the left 1/3rd in the frame). All done within a few seconds. The full shot and the crop (after some sharpening) below :
Look at the amount of details on the Auto (in the crop), and check out the details of patterns on the test mule's rear window area (in the crops posted in the Tata Kite thread). Where was the focus plane ?
Near or Far ??
Before starting the drive, I set the MANUAL FOCUS
lens to approx 12 feet focusing distance, Aperture to F/11 (thro' Aperture Ring of the lens) and Chose Shutter Priority mode with Speed of 1/400 seconds (would've preferred less than 1/500, but for the possible shadows in fading light ...). It is because of "hyperfocal distance
", the picture is reasonably sharper. You can read more about it here Understanding Your Camera’s Hyperfocal Distance
. Those using Auto Focus Lenses will have to adopt a different methodology of choosing "Aperture Priority" and focusing onto something at roughly the distance (corresponding to the Lens Focal length) given in the Table in the link above. Is it applicable to Zoom Lenses ? I'm not sure. BTW
, as I was fiddling to pull the lens cap away, the Lens' focusing ring got disturbed. I don't know, if the Pic improved or worsened due to it.
