High Dynamic Range (HDR) camera tips and setup overview. HDR is basically taking more than one image at different exposures to tame the highlight and shadows that a single exposure normally cannot capture. Most HDR looks gaudy because it is so easy to over process the image. Photoshop CS4 and up have HDR processing capability built in. Stand alone programs such a Photomatix Pro is another option which gives you some more options when processing multiple images. Quick steps to set up for HDR shooting. 1. Set your camera to Aperture Priority mode or lock in a given aperture value in Manual mode and adjust the shutter one up and down from the meter reading. This insures that the depth of field does not change between your images. 2. Either set exposure bracketing or manually take at least three images with one above and below the camera's recommended setting. That's it. Now bring your images into an HDR processing software or CS4 and up to merge them together. Tripod is handy to have, but not always necessary. Good luck and have fun. Video shot with iPhone IV.

The advantage of using high frame rate advance is that there is less time between images for objects to move. Ideally a stationary scene is most suited to HDR imaging. High Dynamic Range imaging can be obtained from a single RAW image, but it is not the same as true HDR though. This technique is most useful for moving objects, although requires some clever post processing. code pour embarquer la vidéo : >>> http://www.youtube.com/embed/ahqnk-I3zV8 <<< |
