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 for further 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.

Other keyboard shortcuts:

1Fit image to screen
2Fill screen with image
5Display at full resolution
<Make background darker
>Make background lighter
spaceHide/dim titles and buttons

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

Stereoscopic 3D image viewing requires a suitable 3D television or monitor correctly configured for your computer. Passive 3D systems such as LG 3DTVs are the easiest to configure for this.

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.

Carletonite is one of the great classics of the locality, known in the past as superb single crystals (see below) . The quality rating for the stuff was redefined by a spectacular find of about 5 years ago which was, as with most such finds at MSH, controlled by the great collector Gilles Haineault. He sold most of them at the time, and I bought a number of them then (though only a few were this good); but this one surfaced again recently and I snapped it up as I have not seen any of comparable quality with Gilles or other dealers in at least 4 years. Some people may prefer the individual crystals (below) but I personally prefer the sheer flash and pizzazz of these incredible blue clusters, jumbly though they may be. All specimens from the find were more or less massive, with good crystals embedded in massive carletonite. The criteria for judging superior specimens are: how big the crystals are; how freestanding of the matrix they reach; and how blue they get. This specimen not only succeeds on all 3 levels but also has the absolute BEST color you could imagine: the richest, most royal, lapis-blue hue. It is spectacular for visual display but also for crystal size as it features a number of crystals to 2 cm jutting out form all sides of the massive carletonite matrix. For display in a collection, it would probably be better mounted vertically with the crown of sharp crystals you see on the left in the top image and on the right in the middle-right image, poking up atop. 7.1 x 4.0 x 2.8 cm
