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.

I simply cannot imagine working in those conditions with nothing but a bandana over your face! Nevertheless, an amazing photo!

At least they have no lice. (Yes, I saw that at a sulfur mining project in Bolivia. Miner brought his louse-infested kids to work with him, and he happily reported that the lice died.)

It's not that bad, as long as you stay out of the actual acid steam clouds.

The combination of poverty and no trade unions is the common reason for bad working situations (think about textile factories in Asia)

Does anyone know what those big tubes coming down the slope in the background are? Giant bamboo? Steel? I wonder what they might be for.

Hi Tom


According to Wikipedia:


"escaping volcanic gases are channeled through a network of ceramic pipes, resulting in condensation of molten sulfur. The sulfur, which is deep red in color when molten, pours slowly from the ends of these pipes and pools on the ground, turning bright yellow as it cools. The miners break the cooled material into large pieces and carry it away in baskets".


Cheers

About 25 years ago I had the opportunity to visit the crater of Poás volcano in Costa Rica with a Costa Rican volcanologist making a routine reconnaissance trip checking fumarole and water temperatures, etc. Ordinarily the crater is occupied by a lake, but this was during a period of increased activity when the greater heat had evaporated most of the lake, leaving only a few pools of intensely acidic water (pH around 0.2!) and lots of fumaroles blowing plumes of sulfuric acid vapor and even yellow sulfur particulates. The ground vibrated under our feet from the escaping gases, and we wore respirators for when the wind blew clouds of vapor over us. My Swiss army knife was hanging on a clip on my belt, and I noticed the next day that the back edges of the blades that protruded from the case were (and still are!) lightly etched from that brief exposure to the vapors!
