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.

Other keyboard shortcuts:

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

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.

PhotosHow would you remove "the crumbles"?

22nd May 2022 02:54 UTCHerwig Pelckmans

Beyond doubt a great photo of a lovely specimen, this zalesiite from Chile.
Congratulations to both Elise and Eric for the artwork and for adding it to the Mindat database.

However, one notices almost immediately all the "crumbles" that most likely fell into the hairy critter when the "vug" was opened.
=> How would you try to remove these grains?

Just curious...
Cheers, Herwig

Briefly hold it upside down in a bowl of pure alcohol. Not water!

22nd May 2022 03:24 UTCHerwig Pelckmans

So the alcohol will not damage the specimen, Alfredo?

Because, I assume,  if put in water, the "hairs" will most likely be "grouped in haystacks" ...

Cheers, Herwig

22nd May 2022 03:32 UTCAlfredo Petrov Manager

Exactly, Herwig. The "surface tension" of water causes that, and the effect is much less with alcohol.

As for damage, some organic minerals are soluble in alcohol, and a few water-soluble minerals can also be soluble in alcohol, and some extremely hydrous minerals (eg: melanterite) can have some of their waters sucked out by pure alcohol, but I don't expect any of this to apply to zalesiite. But don't blame me if you get unexpected and disastrous results, ... as they usually say when giving advice on cleaning minerals: "Try it on a lesser piece first".

 Fully agree with you, Alfredo.
The question addressed in this thread just came to me while admiring the POTD.
Right now I'm not cleaning any specimens, but I will try to keep your good advice in mind for when I do.

Thx for your, as always, expert advice! :-)
Cheers, Herwig
BTW: a regular email is coming your way soon ...

I would add a suggestion to SLOWLY dip the specimen in alcohol.

22nd May 2022 11:06 UTCEd Clopton 🌟 Expert

Before getting the specimen wet with anything, how about just holding the piece with the contaminated surface facing downward and tapping the matrix a few times from different directions?  Provided, of course, that the matrix is robust enough to withstand a little abuse.  One could also try puffing air at it (again with the surface facing downward so dislodged bits will fall away instead of just lodging somewhere else) with a bulb syringe (breath might be too moist and cause things to stick).

22nd May 2022 11:19 UTCDavid Carter 🌟 Expert

Alternatively, just leave the ‘crumbles’ exactly where they are as they form part of the aesthetic. 

It is unlikely that every single one would be removed by whatever method was used to clean the specimen in any event so you would still be left with a few that you might find just as annoying as the amount that are already there!

22nd May 2022 12:29 UTCJolyon Ralph Founder

You could try using photoshop :)

22nd May 2022 13:39 UTCAmir C. Akhavan Expert

Fibers like the one in the bottom right corner will often stick.

I use a fine injection needle or a tooth pick, put a small droplet of glue ("Uhu" or the like) on the tip and let it dry until it feels "dry" but still somewhat sticky between my finger tips.
Then I simply touch the fibers or dust particles with the small glue ball and pull them out. Of course, you need to do this under a microscope. 

Sounds like it needs a lot of patience, but it is much faster than editing it out of the photo (which I also do).

22nd May 2022 16:37 UTCJohn M Stolz Expert

For what it's worth, I think these crumbles add a lot to the specimen's aesthetics.  I suggest taking a minute to re-examine the specimen and consider what they add to form, texture, and content and contrast with what they take away.

Yes, you could use PHOTOSHOP. I use AFFINITY PHOTO. Better and a lot less expensive. Of course it does not remove the crumbs from the specimen, just from the picture. Thats what Jolyon alluded
 to  - :)  It took me about 5 min and a lot of clicking and no alcohol required, except for the glass of wine I sipped on while doing this.

 Must have been a good wine, since IMHO the photo looks much better now. Or ... wait a minute, maybe it's because of the wine i'm drinking??
Cheers, Herwig

My opinion (prior to too much wine, or Cointreau), is as the appearance of the image has been altered, that this is now art rather than photography. I guess its OK to remove objects from images (dirt, fibers, hairs, insect parts and webs, etc.) as long as the caption states so (i.e. foreign objects removed from image by post-processing).

as long as the caption states so (i.e. foreign objects removed from image by post-processing).
 It would be WAY LESS work if people who did not image processing would label their photos as "organic" or something similar ... nowadays almost all photos have been enhanced someway or other... the fact of using stacking is already a way of enhancing the final photo!
Cheers, Herwig

30th May 2022 12:48 UTCAlfredo Petrov Manager

I agree with you, except about the stacking. Stacking doesn't change the actual appearance of the mineral.

31st May 2022 03:28 UTCHerwig Pelckmans

Herwig Pelckmans Expert  ✉️

 Well, I just "followed the logic" of Jeff: in his opinion, a photographer who removes the dust particles that are visible in his photo, should mention that in his photo, because after that removal, he considers the photo to be "art" instead of photography.

In other words: if the photo was manipulated, it becomes art to Jeff. Stacking software manipulates every photo of the stack, and so for Jeff, the final photo at the end of that proces can be nothing else but art.

Removing dust particles IMHO does not change the actual appearance of the mineral, and so to me that is perfectly acceptable without having to mention that.
The same holds true for mineral specimens: we also don't mention that a specimen was cleaned with for example a water gun.
Cheers, Herwig
