Mineral photo specific information

Locality

If the locality is not filled in (it will be if you add the photo from the locality display page - which is a lot easier), you can enter either the full name, a partial name or the locality number. Hitting the "Check" button will allow you to choose the correct location. You can enter just a portion of the locality string here, but if you type in a partial locality where there are too many possible locations, the program will not accept this.


Minerals

The most prominent (or the mineral that you are trying to illustrate) should go on the first line (If it was already not entered).

Adding minerals to photo

Additional associated minerals should be filled in the following fields. After you have entered the mineral - click on the "Find" Button and select the mineral that you were trying to enter. If there are too many possible matches for the mineral, it is possible that it will not be in the list.

An alternate method of filling in the mineral names is to click on a mineral in the Quick List block. When a mineral is clicked, it will be added to the next available mineral entry box.

Type of Photo

You are able to select one of the following types to categorize the photo. Most mineral photos will be either a Full view or closeup.

Types:

  1. Mineral Photo (full view)
  2. Mineral Photo (close-up/photomicrograph)
  3. Mineral Photo (close-up/photomicrograph using layer compositing)
  4. Thin section (normal light)
  5. Thin Section (Polarized Light)
  6. Polished Section
  7. Polished Section (Polarized Light)
  8. TEM
  9. SEM
  10. Cathodoluminescence
  11. UV Fluorescence (Short Wave)
  12. UV Fluorescence (Medium Wave)
  13. UV Fluorescence (Long Wave)
  14. Stereo View
  15. Interference Figures
  16. Mineral in situ
  17. Cut and Rough gem material

For mineral labels - please see "other" category. These should be entered as "child" photos of the main specimen.


Adding Dimensions and a Description

Description

The description should include at least information on the size of the specimens, the minerals, and ideally the method of identification:

  1. A scale of the photograph has to be entered in a special form on the photo upload page (preferably in metric units, mm or cm). You can use the width of the photograph (ie. horizontal field of view is 5mm; or horizontal fov 5mm) or largest crystal is 3.0cm high. You are welcome to add that information to the descriptive text, too. Objects that are presented as a scale on the photo with the specimens are acceptable as long as they are not too obtrusive. Coins are probably not a good size guide since most people would probably not know what is the size of a particular coin.
  2. Explain what is seen. Do not presuppose that visitors are familiar with the minerals on the photo. If there are a number of minerals on the photograph, you need to describe which crystal is which mineral (e.g. "green crystals of mineral X on white crusts of mineral Y"). You should also include other information such as habit or pseudomorphism if these are applicable.
  3. We appreciate information on how the minerals were identified ("visually", "dealer label", "museum label", "analysed with method X by person Y at University Z", etc.). Photos of species that are difficult to identify, rare or unusual may be rejected without this information.
