Fisheye Facts & Fantasies; Get The Most From Fisheye Lenses Page 2
Fisheye Fact No. 8. Yes, you can use a fisheye to photograph people. Try to keep them in the center of the frame to minimize distortion.
Fisheye Fact No. 9. You don’t need a fisheye to give an image that characteristic look. You can use software. However, since parts of the image may be lost at the edges, make sure you have plenty of breathing room surrounding the subject. Taken too far, this step results in degraded image quality.
Fisheye Fact No. 10. By the same token, fisheye distortion can be corrected with varying degrees of success in post. This process also may come at some expense to the overall integrity of the image.
Fisheye Vision: Some Caveats
• Unobserved elements may intrude on the picture space. That includes your feet on the ground, a tripod leg, or a finger at the front edge of the lens barrel, or someone entering the shot.
• Make sure the fisheye matches the sensor size of the camera. Specifically, many of the fisheyes being introduced today are aimed at APS-C-sensor D-SLR cameras, not full-frame digitals. Also, using a fisheye designed for full-frame sensors on APS-C cameras will truncate the fisheye effect.
• Using filters: because of the protruding nature of the front element, fisheye lenses don’t accommodate front-mounted filters. Some fisheyes, however, will accept rear-mounted gelatin filters. It is rare that a fisheye will come with a built-in filter turret that lets you dial in the needed filters. Sadly, there’s no room for a polarizer on a fisheye.
• The built-in petal-shaped lens shade protects against flare, but it does little to protect against the elements, wayward fingers, and flying debris. And be especially watchful of protruding twigs, branches, and such as you move closer to your subject, since distances are deceptive. So keep a watchful eye on the front element without losing sight of the subject.
