The Limestone mines at Mønsted

The scale of this mine is striking; this giant ant nest is a labyrinth of 60 km of passageways with enormous caverns and narrow tunnels. Approximately 2 km of the 60 km of passageways are lit. A multi-media presentation shows the history of the mines. Exhibitions and films tell about bats, geology and mining.

The first mining activities recorded are dating back to medieval times, back then was the carried out of the mines, this took place up to year 1826 where king Frederik 6 commanded hoists to be made.

The limestone of the Caves of Mønsted dates back to the same period as the limestone of Bulbjerg and the upper parts of Stevns Klint. That the limestone of Mønsted reaches the surface is due to a deep-seated salt dome that lifts the limestone to the surface.

Getting there

Mønsted Limestone Mines



As a photography object it is a treasure, framing and compositions is easily found. Remember your tripod as long exposures are need and flashes are frowned upon.

Brattingsborg Voldsted

This is my second visit at Hald Oaks, and the lake. The area around Hald Lake southwest of Viborg is quite unique. Glacier flows met at this place during the last Ice Age, and melt shaped an almost dramatic landscape with hills, slopes, ravines and a very deep lake.

Not far from Hald ruins (a late medieval castle, bishop Hald). In this area are there a number of mounds, where the oldest is Brattingsborg which probably was built in the 1200s. The fortification is located on a hillside and consists of two quadrilateral banks. The one knock has probably been intended for defense and the other for habitation. Brattingsborg was probably abandoned when Niels Bugge in the mid-1300s built his castle some hundred meters southwest.

Long Exposure No Neutral Density Filter

For a long time I have wanted to venture into the realm of long exposures, the prices of dreaded Lee filters, contradicting opinions on the value of such expensive filters vs the value and effect of low priced Camdiox, and finally the hopeless versions of glass you would attach to your Samyang 14mm f/2.8 just utterly useless, pricy and cumbersome.

This new technique (for me) quickly has become my favorite technique, when shooting water. The use of long exposure photography but without a filter, keeping the shutter open for an extended period of time, creates the unique effect of smooth and silky looking water.

The technique explained

You take a number of exposures for arguments sake 10 exposures with the same settings of 30sec, f/22 at ISO100. What happens is when you combine these photos in the post processing they become number of exposures times 30sec giving you a exposure of 5 minutes and here is the neat thing the ISO-100 is to be divided by the number of exposures giving you an effective ISO-10. If you have been shooting Milkyway you possibly have been using this technique to remove noise.

You could argue that you could use this technique handheld, but to my experience is the success rate too low. This technique is depending on a tripod as the photo has to be aligned perfectly.

Hald Oaks

If you have visited my blog before you will know this is a place where share my photos and insights behind the scenes of my shoots. If you have any questions please feel free to shoot me an email or leave a comment below!

This time we visited Hald Ruin (Hald Ege Ruin). The ruins still feature remains of basement vaults and parts of the castle entrance with gun slits for guns and bearings for shafts for two drawbridges. The castle dates back from 1528 and are freely accessible. The castle tower is a later addition from the 1800. The castle ruin is situated on a small peninsula in Hald Lake just south from Viborg.

I knew that colors wasn’t going to be lush, the snow had covered everything not many days ago. Thick clouds gave a very uninteresting sky, but at the same time a very eve light. I knew it was a day of experiment, trying to get the most out of the beautiful nature and the historic surroundings. The techniques I wanted to try out were Long Exposure Photography without ND filters, and I also wanted to develop my HDR photography, trying the technique on less obvious targets.

Arching entrance overlooking the tower

My First HDR was taken inside the basements vaults; portraying the arching entrance, with banks and tower just outside. To my horror, I noticed how the restorations has been performed, the granite ashlars was plastered with some kind of cement, looking awful fake.

The cellars from the outside was fare more compelling. Flat light and water in the air gave very shiny expression to the stones. HDR allowed me to pull details out from the arching entrances. The keep is dating back to the 1300, but is still standing strong. This photo made me make a promise to myself; I absolutely need to retake this frame in early spring. Red stones, granite boulders, framed in lush green on a blue background; maybe even taking this photo backlit.

The entrance

A path crosses a wooden bridge, and continues into the keep. It narrows between two banks and ends at the central tower. I used HDR again, allowing for a little more play in the clouds, will the barriers still is well exposed.

The Entrance seen from outside.

The original old wooden bridge is protected by a new bridge placed right on top of the old bridge. The bridge crosses a deep trench and allows easy access to the keep.

This time I used a slightly different technique. Taking the same picture 10 times and stacking them in Photoshop with mean I was able to smoothen the waters. The photo was taken with ISO 50 f/22 ½ of a sec. But by averaging out the photos the exposure is equal to 10×0.5sec at ISO 50/10. The effect is high detail and smooth water. It is a technique I used in many of the following examples. Do notice how it affect the water, much like long exposures with an ND filter.
