Photography Guide

A quick guide on getting images ready for use on e-Rocks.

This guide is designed for sellers, but collectors who publish collection inventory should work within these guidelines too.

The concept is that all published images in our main database have a consistent presentation across all users on the site.

The presentation of adhoc images via blogs/posts and into database photo galleries should also be considered along these lines - though this area is more liberal.


e-Rocks’ buyers need sellers to use simple photographs so they know what is coming through the post!

What is simple photography?

Mineral specimens must be:-

  • staged as they would appear in a collector’s case.
  • dry, free of dust, dirt, tack, scales or fingers
  • photographed on a black/white/graded or shaded grey background
  • free from photoshop or otherwise manipulated image or image backgrounds
  • represented with the natural colours of the item being displayed

We all have to see clearly what you are selling


  • minimum number of pictures is 2
  • one of your pictures must show the whole mineral
  • the chosen thumbnail picture should be cropped to present a reasonable image of the mineral or a label - not both
  •  UV pictures are welcome but do not set UV pictures as the Thumbnail, unless it is an auction of UV minerals only!

e-Rocks has final say on photos – if they don’t comply they have to be changed!

Photographic Dos!

Use good daylight (lamp) light source – Neutral Black White Grey Background – no flash!

One picture MUST show whole mineral

Use macro lens/feature on camera to show close up of main features of specimen (and any problems too!)

Photographic Do nots!

Do not misrepresent natural colours and do not over compensate with photo editor

Do not use scales, rulers, fingers or too much mineral tack in your photos

Do not photograph objects that are wet or dirty!

Do not upload blurry photos - Keep things sharply in focus

Do not show items in groups - Only show one mineral at a time!

Do not use complex or textured backgrounds

Do not use coloured backgrounds

Do not use legends/logos or watermarks
