How to use the mindat.org media viewer

Click/touch this help panel to close it.

Welcome to the mindat.org media viewer. Here is a quick guide to some of the options available to you. Different controls are available depending on the type of media being shown (photo, video, animation, 3d image)

Controls - all media types

Zoom in and out of media using your mousewheel or with a two-finger 'resize' action on a touch device.

Use the mouse or your finger to drag the image or the view area of the image around the screen.

< and > at the left and right hand side of the screen move forwards and backwards for the other images associated with the media you selected. Usually this is used for previous/next photo in a gallery, in an article or in search results. Keyboard shortcuts: use shift + the left and right arrow keys.

< and > in the bottom center are used for switching between the photos of the same specimen. Keyboard shortcuts: use the left and right arrow keys.

>  in the bottom center, raises the information box giving details and further options for the media,  <  at the top of this box then hides it. Keyboard shortcuts: use the up and down arrow keys.

? opens this help window. Keyboard shortcuts: use the H key or the ? key.

Scalebar

If the field of view (FOV) is specified for the photo, the scalebar appears in the left bottom corner of the viewer. The scalebar is draggable and resizeable. Drag the right edge to resize it. Double click will reset the scalebar to it's default size and position. If the scalebar is in default position, double click will make it circular.

Controls - Video

Video files have a standard set of video controls: - Reset to start, - Skip back, - Play, - Pause, - Skip forwards. Keyboard shortcuts: You can stop/start video play with the P key.

Controls - Animation (Spin Rotation)

Animation (usually 360 degree spin rotations) have their own controls: - enable spin mode. Note that while images are loading this option will not be available but will be automatically activated when the animation has loaded. Once active you can spin the image/change the animation by moving your mouse or finger on the image left/right or by pressing the [ or ] keys.

The button switches to move mode so that you can use your mouse/fingers to move the image around the screen as with other media types.

The button, or the P key will start playing the animation directly, you can interrupt this by using the mouse or finger on the image to regain manual movement control.

Controls - 3D Stereoscopic images

If a stereoscopic 3D image is opened in the viewer, the 3D button appears in the bottom right corner giving access to "3D settings" menu. The 3D images can be viewed in several ways:
- without any special equipment using cross-eyed or parallel-eyed method
- with stereoscope
- with anaglyph glasses.
- on a suitable 3D TV or monitor (passive 3D system)

For details about 3D refer to: Mindat manuals: Mindat Media Viewer: 3D

To enable/disable 3D stereo display of a compatible stereo pair image press the 3 key. If the left/right images are reversed on your display (this often happens in full-screen mode) press the 4 key to reverse them.

Controls - photo comparison mode

If a photo with activated comparison mode is opened in the viewer, the button appears in the bottom right corner giving access to "Comparison mode settings" menu.

Several layouts are supported: slider and side by-side comparison with up to 6 photos shown synchronously on the screen. On each of the compared photos a view selector is placed, e.g.:  Longwave UV ▼. It shows the name of currently selected view and allows to select a view for each placeholder.

Beryl (Var: Emerald) : Be3Al2(Si6O18), Quartz : SiO2

Dimensions: 7 cm x 4.5 cm x 4 cm

This is quite simply the best matrix Brazil emerald known, and has been featured on the back cover of Le Regne Minerale in 1998 and in a photo in the Min Record as well. It GLOWS with color. Steve has owned this since the 90's. The pocket was found in 1997 and it was sold to noted french collector Gilles Emmringer. He had one of the best collections of fine quality Brazilian gem crystals at the time. Shortly thereafter it was exchanged to Steve Smale. Since its deaccession to Smale, Steve has owned it as one of his marquis gem beryl specimens, well-known from being shown at Tucson and at his home You simply cannot find an equivalent emerald from Colombia or Nigeria , as this rich matrix look remains unique as well. In person, the color is a very glassy and rich hue of green that gem people tell me has a "hint of blue" in it. The result is a very intense color that stands out in brightness from the rather more common, and still expensive, Colombian material. There is simply not another matrix emerald like this, to our knowledge, anywhere on the planet. The piece is large, at 7 x 4.5 x 4 cm overall. The crystal is also of good size at 3.5 cm tall, 2 cm wide, and 1.5 cm thick. It is again, extremely glassy and bright. The extra color pizzazz contributed by all the small crystals on the side of the central quartz contributes a lot of visual impact and helps to "centre" the eye on the middle. EVEN IF THIS WERE COLOMBIAN, it would fetch a very high price for the aesthetics and color brilliance of the large emerald. The fact that it comes from Brazil, from a much rarer and smaller discovery that seems to have been a one-time occurrence, makes this far more significant than any comparably sized Colombian piece could be, however. I consider myself fortunate that we were able to make an exchange with which we both feel happy (he still has one of the best Colombian matrix emeralds!), to acquire this specimen. It was not for sale, only for trade, in other words. Comes with custom lucite base for easy display. 7 x 4.5 x 4 cm
