Best photographs of specimens larger than 1cm

Posted by Rudolf Hasler  
Rudolf Hasler March 28, 2013 11:11AM
When scrolling through Mindat's photo galleries I can see lots of excellent photographs of micro mounts but not very many of larger specimens.
The reason for this might be that people who specialize on micro photos are mostly real experts while photographs of larger specimens (measuring at least 1cm) are usually made by collectors like myself who are more interested in collecting than in photographing.
With this thread I want to invite all collectors to show her/his best photographs of specimens larger than 1cm. Everybody can show his own favorites side by side. These photos can be exchanged whenever somebody thinks she/he has new better ones.
The result might be a very nice collection if many follow my example. Please, don't let me stand alone with my pictures!

Thanks guys. They represent a LOT of field trips though. And I only helped collect two of them.

Tim - yes that is a unique howlite. We've never found one so well exposed before.

What I don't understand is why more people haven't added their best pics. I was really looking forward to this thread growing quickly.

Hello all !
Nice pictures indeed !
But... a question : do you use a stacking software (Helicon Focus, Combine Z, Zerene...) ?

Best regards

Hello Jean-Marie,
I think that most of us are using stacking softwares.

Those are very good pictures and very fine specimens. These two attributed often do not go together in our image gallery, but here they do. They will be good additions to our best minerals articles.

Rock Currier May 26, 2013 10:11PM
That's a good picture. On my monitor however the black in the crystals, especially on the left side seems to make the left side of the crystal disappear into the background. I took the picture into Photoshop and increased the dynamic range of the image, or lightened the shadows as they call it and the result is below.

I think it looks a lot better. Knowing how careful with color and light and your background as a color scientist I have to assume that the image you downloaded did not look like it appears on my monitor. My recent work on some of the Best Minerals articles, especially all those black schorl specimens makes me think that perhaps most images that are uploaded to mindat have their dynamic range downgraded automatically by the upload process and it might be a good idea to develop an algorithm to automatically increase the dynamic range of uploaded images when needed if that would be possible.

I would be interested in your thoughts on the matter.

Hi, Rock,

Playing in Photoshop can change a lot of things in an image, some for the better. Your manipulation is OK but the uploaded image is a JPEG and any manipulation of JPEGs can actually make it worse. An automatic enhancement as you suggest would not be good for a lot of the images. The enhancement that you did may look better to you, but it is not very representative of the specimen itself. Its kind of un-natural. The dynamic range in the original specimen as I look at under normal lighting is closer to what I have uploaded.

Rock Currier May 27, 2013 01:46AM
So the picture you took didn't show a distinct edge to the crystal of tourmaline?

Rock Currier

Mineralogical Research Company May 27, 2013 03:18AM

Your monitor may not be displaying the full dynamic range of the image. Those $129 monitors from Costco don’t make it. A man of your means can surely afford a good one. :-D I think Ron has it right on. The left edge is just barely perceptible on my photo editing monitors, so the full range of dark to light is nicely reproduced. I find the photo to be very pleasing. Nice shot Ron!

Paul Brandes May 27, 2013 03:57AM
The original photo looks fine as it was posted on my monitor with no fading to black as you saw, Rock. In all honesty, the photo after you Photoshop'ed it looks unnatural now, as though there is too much light on the subject or it was overexposed when the photo was taken. The only slight knock I have on the original photo is that to me it is still too shiny with the light reflecting back off the specimen, but that's just me.

Manipulation of images is as old as photography. I remember before the digital age when I used dodging paddles to selectively adjust the exposure in certain areas of a photo. Some people took the adjustments too far and the result was more art than documentation. For minerals I think documentation is far more important than art and photoshopping should be restricted to improving the presentation without introducing any kind of distortion of reality concerning the specimen itself. Change the backgrounds all you want but try to present the mineral image honestly and as realistically as possible. I feel that "edge sharpening", e.g., "unsharp masking", "sharpen edges", etc., "shadow" and/or "highlight" adjustment, "color correction", etc. is sometimes overused to the point of making the mineral look "unnatural" even though the image is very impressive. Don't get me wrong some sharpening is definitely an improvement, it is only when carried a little beyond that it becomes too much.

Because of camera metamerism, white imbalance, etc., some "color correction" may be necessary, but if your monitor is not properly setup with a decent color profile, you could do more harm than good. It might look good on your monitor after your corrections but not on anyone else's monitor.

I am totally against any automatic processing by MinDat on upload (other than scaling of size). Let the photographer and/or uploader be responsible for their own photos. Any auto processing exposes MinDat to all sorts of complaints, criticism, etc. and should be avoided at all costs.

Harjo Neutkens May 27, 2013 10:28PM

BARITE in the American Midwest is found in a variety of circumstances. In the Michigan copper country, it is found very sparingly. It is common and quite collectible in the Illinois Kentucky fluorite area as it is in the Elmwood Tennessee mining area. In Midwest quarries, perhaps the best crystals come from the recent finds in Iowa. There are many small and localized sites where it can also be found. In the sedimentary geodes of the Midwest, it is common, but, by far, the best and largest BARITE crystals are found in the geodes of south-central Indiana.This geode, from Monroe County, Indiana collected in the 1980s, is 14 cm x 9 cm and contains a single stout 5 cm x 3.8 cm x 0.9 cm thick crystal. Tiny marcasite and/or smythite crystals are included into the barite; this is quite common. CHEERS……BOB

Whereas I normally photograph micro-mounts, Sharon has had me photographing some of her thumbnail collection recently. So, for me, these are gigantic specimens (they do exceed 1 cm) and present their own problems in photographing them. Of course, she had to provide me with a decent macro lens in order to start the project. :-)

I have a lots of pictures taken before the Stacking got popular and many of those are already posted in my albums on Facebook and elsewhere. Pictures posted here are so good that they show all information about the specimen so fast that it is overwhelming and kind of shocking.
Now my question is; Should I go and re do all my photos or do my old photos provide the enough visual information about the specimens.
Anyone that has the time please look at some examples here;
Part of this was taken with 4MP Nikon Coolpix 4500 and part with the Olympus C 8080. I still use both this Cameras despite the Nikon D90 that is sitting here unused.
Rudolf Hasler April 06, 2014 07:17PM
I had a quick look at some of your pictures in facebook and I wish all my pictures were as good as yours. There is no need in my opinion to redo them. If I were you I only would take new pictures of those that I am not content with. That is what I often do with my older pics.
