4:1 – Re-imagining the Frame

Hi Folks:

As photographers, one of the most important challenges for us is to continue to change how we see and to stretch our creativity. One of the ways to do that is to pick specific parameters and then to make a body of work that fits within those parameters. It might be to shoot only one subject, to shoot only in grayscale (B&W), to make an image every day… In the film days, most people’s relationships to photography revolved around a few aspect ratios: 2×3 (4×6), 4×5 (8×10), 5×7, etc. With some older cameras we also had 1:1 square prints, usually from 120, 127 or 620 film. With digital photography we’re not so limited, although some of the same rules apply when we get to printing. Movies (and now video) have always embraced wider frames, although there was no one standard aspect ratio. We have movies made in 1.78:1 (16×9) out to 2.4:1 (22×9) and beyond. Outside the movie theatre, for the average person 16:10/ 16:9 showed up in their lives with the first widescreen computer monitors and digital TVs. Continue Reading →

Panoramic Photography and Stitching “Errors”

Hi Folks:

In a previous post I rambled on a bit about panoramic photography – basically a system where one combines several images into one using software designed for that purpose. One can also take several images of the same scene at different exposures and combine them into one HDR image using the same software. Mostly I use Autopano Pro for stitching, although I’ve also used Hugin, and since I work extensively in Lightroom I’ve been playing a bit with Photoshop CS5‘s HDR Pro and panorama tools as well. To create a stitched image the software looks for the same points in two or more images and assigns them as ‘control points’. The combined image is then mapped around those control points. Usually this works very well, but in my previous post I talked a bit about parallax errors and things like that, and sometimes these images don’t get mapped together perfectly. This can create situations like this: Continue Reading →
