We just know 2015 is going to be a great year, and to make sure it gets off to a good start we have an upgrade for our filming services: we now offer our wide lens option as standard equipment on all new time-lapse projects.
Offering a 97 degree horizontal angle of view (HAOV), the wide lens has been a popular option on various projects, especially those in confined spaces or where the camera can only be placed close to the subject. A wide view can also be useful to capture a site with one camera rather than multiple cameras.
The angle of view of a camera/lens combination can be drawn onto a site map to give an idea of what the camera will see. If a wide view is not desirable, our wide lenses can be zoomed-in to suit.
We’ve been using Sigma 10-20mm wide zooms since Construct Films opened its doors in summer 2013. The Sigma is a robust, compact lens. Recently, Canon has launched a new 10-18mm lens and in our tests it delivers improved sharpness and lower distortion. We’ll be using both of these models in future client projects.
The view through a wide lens almost always suffers from barrel distortion — where verticals aren’t parallel, close-up objects appear larger than they should, and sometimes the whole picture can appear off-level. Sometimes distortion can look attractive, but this is rarely the case with construction photography where the subject is usually a geometric shape with mostly straight edges. When we edit our time-lapse video clips, we can correct for this distortion somewhat while maintaining good image quality.
When an extreme wide view is needed, we also have an optional fish-eye lens. With an insane 175 degree-wide view you’re almost guaranteed to get everything in the frame, but you have to accept some big distortion and vignetted corners.
Now all projects can be captured in wide angle view. If your project could benefit from time-lapse photography and real-time site monitoring, contact us now.
