10. Photo Link Manager – Part Two • Field Practices • Photo Storage • Irfanview – Resample Photos • Create and Update Links to Photos in Directory via Date Match • Manually Create, Copy, and Delete Photo Link Records

11. Field Practices • Check the time on your camera at the beginning of each day. Make sure it is close to the time on the GPS. • Make a habit of recording your GPS point at the same time you take pictures. The time stamp stored on the GPS and with each photo is what is used for date-matching. • Take photos in an orderly and consistent pattern to maximize the value of the visual information. Example: • Take site photos across slope and with the pedon in the field of vision. • Use a flash if under dense cover. • You may never return to the site. Take extra pictures of landforms, vegetation close-ups, or anything that may prove valuable when correlating the site at a later date.

12. Photo Storage • When saving photos from your camera, use a logical directory structure that will ensure photos are linked to the correct site observation. • Example: Describer (MM,SS)

13. Date-Matching and Updating Links • If desired, filter the Analysis Form to a selected set and open the Photo Link Manager. • Open Photo Link Manager and Browse to the folder where the photos are stored. • Run Date-Match • Check the links created by the Date-Match process.
