Panoramas Shoot with the Camera Positioned Vertically As This Will Give the Photo Merging Software More Wriggle-Room in Merging the Images
P a n o r a m a s What is a Panorama? A panoramic photo covers a larger field of view than a “normal” photograph. In general if the aspect ratio is 2 to 1 or greater then it’s classified as a panoramic photo. This sample is about 3 times wider than tall, an aspect ratio of 3 to 1. What is a Panorama? A panorama is not limited to horizontal shots only. Vertical images are also an option. How is a Panorama Made? Panoramic photos are created by taking a series of overlapping photos and merging them together using software. Why Not Just Crop a Photo? • Making a panorama by cropping deletes a lot of data from the image. • That’s not a problem if you are just going to view it in a small format or at a low resolution. • However, if you want to print the image in a large format the loss of data will limit the size and quality that can be made. Get a Really Wide Angle Lens? • A wide-angle lens still may not be wide enough to capture the whole scene in a single shot. Sometime you just can’t get back far enough. • Photos taken with a wide-angle lens can exhibit undesirable lens distortion. • Lens cost, an auto focus 14mm f/2.8 lens can set you back $1,800 plus. What Lens to Use? • A standard lens works very well for taking panoramic photos. • You get minimal lens distortion, resulting in more realistic panoramic photos. • Choose a lens or focal length on a zoom lens of between 35mm and 80mm. -

Monitoring Photo Fl08
Monitoring with Panoramas and Fixed Photopoints: Monitoring recreational impacts, and assessing habitat change from the office using panoramic and fixed photopoints. Chip Young Trail Specialist Florida Fish and Wildlife Conservation Commission (FWC) Office of Recreation Services Panoramic Photopoint = multiple photographs taken from one specific point, stitched together to form a single image. Fixed Photopoint = single photograph taken at a specific point in a specific direction (bearing). Why use fixed and/or panoramic photopoints for monitoring? !! Shows condition of area at one place and time. !! Shows change over time at a particular place. !! Possible to monitor many areas in a relatively short period of time in the field (to be later assessed from the office). !! Quick and easy. FWC lead management areas with developed recreational opportunities Shows condition of area at one time and place. Shows change over time at a particular place (site condition) FALL 2007 SPRING 2008 Shows change over time at a particular place (inventory). FALL 2007 FALL 2008 Situations where photopoints are utilized as an efficient way to monitor impacts. !! Trailheads !! Points along trail !! Parking lots !! Camping areas !!

Unreadable content – to low resolution Digital Master material is removed after creation of web delivery formats Lack of text recognition . Even the best metadata is not as useful as properly recognized and indexed text “A digitization project has many dimensions and no two digitization projects are identical.
