Last week I wrote a bit about the reasons tilt-shift lenses were becoming more popular in the DSLR world. This week I’d like to provide a simple example of using tilt in an image to increase effective depth-of-field, and offer a basic overview of how that’s done.
To demonstrate what a difference this can make, I ran a quick example with and without tilt using the older ::amazon(“B00009XVCD”,”Canon TS-E 24mm f/3.5L”)::. (To make the effect a little more apparent on these small screen samples I focused the image without tilt near the “near” lens cap. Of course, in that image I could have chosen to focus farther into the image–which would have blurred the near image somewhat to reduce the blurring in the far image, but both would have still been out of focus. Both images were taken at f/3.5 with a ::amazon(“B000V5LX00″,”Canon 1Ds Mark III.”):: (more…)
