Introduction


A summer's day in July. The weather was warm and sunny, beckoning us out on an other adventure. We decide to go looking for some historic sites so we have a look over the OS map and notice there seems to be a fair amount happening around Tealing way. So we chunter out and have a look at Tealing Doocot. Very Nice! And very well preserved. Well worth popping in to have a look.


Tealing Doocot. Interesting!

Just down the road is the Tealing Souterrain. Again, a very interesting historic piece and easy to get to.

We then go to inspect some standing stones located in a field. They were not as easily accessible as we might have hoped. We had to pop over a couple of barbed wire fences and through a bog to reach them.

The standing stones. Were they worth nearly getting castrated to see?

After the standing stones we had to head back to the car. Back over the barbed wire fences again! On our way back along the road we noticed something lying on the road. What was it? A pair of women's undies. The mind boggles as to the reason they were left there. Anyway, we did the honourable thing and picked them up and stuck them on the branch of a tree.

Keeping the roads safe from offending objects

After our good deed for the day was done we returned to the car. It was still early in the day and we couldn't find any other historic sites to visit in the area. What to do? Well, there were a few nice looking hills over in the distance, so let's get going up Auchterhouse Hill!

Getting There and Parking Up


You can see these hills for miles in the surrounding area and there are many different ways you can attack them, with numerous paths to and fro. Your best bet is to use the car park at Balkello Woodland although we chose to park at North Balluderon Farm which is also good but there is less space to park.

The Balkello Woodland car park and North Balluderon Farm can be accessed from a minor road running between Kirkton of Auchterhouse and Tealing. Both settlements are well signposted and easy to find so you shouldn't have any trouble. If you are not familiar with the area your best bet would be to head along the A90 Dundee to Aberdeen road and turn off for Tealing from here. Then take the minor road running west from Tealing to Kirkton of Auchterhouse.

Men of the Hills


We park up at North Balluderon Farm. The sun is beating down so we check the car's thermometer before going out. It read Scorchio! That is 27oC to normal peope. So anyway, we got out of the car and started heading up the path.


Our Goal


The path up is fairly gentle at the start but it is still hard going because of the heat. As we continue round we are nipping behind trees for a spot of shade and to cool down. We didn't bring any sunscreen with us or any hats or suchlike to keep the sun off our faces. Doh! Thankfully the trusty OS map worked as a nice makeshift sun hat.


Me trying to cool off. A sombrero might be better!

After a while of walking west around the base of Balluderon Hill, the gradient started to increase as we headed up the path towards Auchterhouse HIll. As we continue up, the woodlands disappeared and there were no shady spots to get out of the sun. We were really feeling it as we climbed up. To rub salt in the wounds, we meet this bloke and his bird walking back down. We are almost on our knees from exhaustion and they are bounding happily down the hill. Are we really that unfit? Because they certainly didn't look like they would be entering the Olympics any time soon.


A couple of walkers who must have asbestos skin.

With steely determination we climb on. Every step felt like a trial. We eventually came up to a patch of heath atop a small mound close to Auchterhouse Hill and just threw ourselves down. We were fucked! With our bodies tired and mouths as dry as a nun's crutches we were in serious need of liquid refreshment, so it was time to crack open the wonder potions.

 
That was a tasty beverage.


That caffeinated, chemical ridden cola surely hit the spot. As we sat drinking and contemplating life,  we noticed a small critter crawling through the grass and onto my OS map / sunhat.


The determined caterpillar

For some reason we were fascinated by this caterpillar crawling around. Maybe it was due to delirium from the heat or maybe we just needed an excuse to sit on our arses a while longer and rest. Anyway,  just like Robert the Bruce and the spider, the caterpillar's relentless determination must have rubbed off on us and we decided to get moving again.


From our resting spot we can see Auchterhouse Hill

We had found our second wind. In addition to the stoic and inspirational caterpillar, the shot of caffeinated juice and the sit down, some clouds had moved overhead and were providing welcome shade. We bounded towards the summit of Auchterhouse Hill.

Eventually we made it. We reached the flattened peak of this hill where a fort once stood. Unfortunately, there were no remains of the fort still standing but there were stunning views across landscape. Well, mostly stunning views....


Where's the fort?



Most of the views across the lowlands looked amazing. Even Dundee didn't look that bad from up there but there was one howler that stood out and marred the landscape. A new housing development at Auchterhouse. Although I firmly support new housing developments in rural locations and welcome innovative design, this looked crap. They were big, hulking, standardised designs with towers on them. Yes, bloody towers! I know Auchterhouse has a reputation for being a bit knobby but housing schemes with towers just looks ridiculous.

The palatial yet unsightly new housing development

So after having a seat up Auchterhouse Hill and admiring the views, we are eastbound and down over to Balluderen Hill.

Enjoying yet more of the sun.

The walk between the two summits was not too bad. The path was good and the gradients not too steep. Before long we get over to Balluderen Hill and are greeted by this impressive monument erected to Sydney Scroggie - The Man o' the Hills.

The plaque to Sydney Scroggie

If you thought that little caterpillar was inspirational, check out this guy. Here is a piece about him

William Sydney (Syd) Scroggie
1919 - 2006 
 
Inspirational hill-walker, author and worthy. Born in Canada, Scroggie was brought to Dundee as a baby, his father having died of wounds received during the First World War. He was educated at John Watson's Institution (Edinburgh) and the Harris Academy (Dundee) before joining publisher D.C. Thomson, where he was employed as a sub-editor of The Hotspur comic. In the last months of World War II, while serving as an officer in Italy, he was injured by a mine and lost his right leg and the sight in both eyes. However, he learned Braille at St Dunstan's in London and studied for a time at New College, Oxford, before returning to Dundee, obtaining a position with NCR, where he spent the remainder of his career.

With good humour and determination he overcame his disabilities to return to his beloved hills, walking thousands of miles and making more than 600 blind climbs. Describing his blindness as 'a sort of adventure', he inspired many by refusing to let it limit his life. He taught himself Greek and became a published poet and author, with works including the book The Cairngorms: Scene and Unseen (1989) and a collection of his poems Give Me the Hills (1978).

Scroggie appeared on the television programme This is Your Life in 1964 and was awarded an honorary degree by the University of Dundee in 2001.

He died at his home in Bridgefoot (Angus). He is remembered by a cairn on Balluderon Hill in his beloved Sidlaw Hills. A rare honour for a living hill-walker, this was built in 2000, and Scroggie walked up the hill for the official unveiling, despite being aged 81 at the time.

And here is a video of him on the famous Weir's Way.



So after reading the plaque and admiring the views from the hill we thought we would have a welcome sit down. We weren't feeling as knackered as earlier but we were getting mighty red and knew we were going to feel it the next day.

Looking a bit sunburnt there.


A seat in the shade whilst I roll one up.

That was enough for us. We had made it to the summit of both the hills and had got far too much sun in the process so we decided to head back to the car. The other hill in the area, Craigowl Hill, would have to wait for another day.


Craigowl Hill. That's for another day.

As we had seen enough of the sun we decided to take the quick route back down through the heath. We had to watch where we were going though as there were a few steep drops.

Don't want to go down that way

The quick way down

So after a very quick descent we were back at the car and on our way home.

Heading Home - Reflection


It was a good day out made overly demanding by our lack of preparation. The climbs up the hills are not too strenuous and you are rewarded with some great views over the area. We just made a meal out of it by not having any decent supplies with us such as suncream, plenty of liquids and at least a hat to shade us from the sun. Thankfully, all we ended up with was a bit of sunburn but it is worth bearing in mind that heatstroke can be fatal so make suitable preparations before you head out.

As for photography, it really wasn't something we were thinking about too much on this day. However, bright sunny days will usually yield some good snaps and this was no exception, so we got some interesting images of our outing.

Worth a visit?


Definitely worth a walk up. It's not too severe and there are good paths all around. It's close to Dundee so if you are local you don't have to travel far to get there. Just make sure you take suitable equipment and supplies for the day, unlike us!

Photography Time - Introduction to HDR


An HDR capture from the beach at Lower largo in Fife


Introduction


HDR is an increasingly popular photographic technique. With the evolution of cameras and dedicated HDR software many more people are trying it out. I have mentioned it previously in other posts and posted a few photos but now I will try and give a more detailed explanation of what it actually is. 

n.b. HDR photography can be quite complex and I am certainly no expert but in this post I will give a brief overview of the technique and how to use it.

What is HDR?


HDR stands for High Dynamic Range. The dynamic range is the range of darks to lights within a scene or photograph. The sensor within a camera cannot handle such a wide dynamic range as the human eye can and this can lead to parts of photographs coming out under or over exposed although they did not appear so to your eye.

If you want to test this, stand in a room on a sunny day a look out the window. (Warning: make sure the sun is not shining directly in the window as you can damage your eyes.) You should be able to see all parts of the scene, in your room and outdoors, without any area being excessively light or dark. Now pick up you camera and take a photo of the scene you have just been looking at. Depeding on how the camera is metering the light, you will end up with either the outdoor part of the photo being too light and overexposed or the indoor part underexposed and too dark, or both. You can fiddle around with the camera's exposure as much as you like but you will still not make it capture the scene as your eye sees it. Not many people realise this dynamic range problem exists and end up frustrated when their photos don't look as they expected.

HDR is a photographic technique that attempts to overcome this issue by expanding the dynamic range of a photo. It is usually used for scenes that have a wide range of darks to lights but can be used for any scene.

How is it done?


HDR works by combining multiple exposures of the same scene into one image. It can be done with one photograph (I will discuss how to do that later) but most commonly it is done using upwards of 3 photos of the same scene taken at different exposures. The photographer takes a number of shots of the same scene ranging from underexposed to overexposed and then uses software to merge these photos together. The software tries to fuse these multiple exposures together to produce an image with a balanced exposure.

Sounds straightforward! In theory it is but in practise it is not quite as easy as you might think and the results often range from surreal to downright terrible.

First off, before we discuss the merging process, I talk a bit about the capture process.

Multiple Exposures and Exposure Bracketing


To get the snaps you need for pumping into the software, you will have to take a number of shots of the scene at different exposures. The easiest way to do this is to use the exposure bracketing function on your camera (if it has this option) This option allows you take multiple shots at different exposure intervals with one click of the button. The bracketing interval for HDR is usually set between 1 and 2 stops depending on the scene. A wider range is better for scenes with more extremes of light and dark.

If your camera doesn't have exposure bracketing then you will have to set the different exposures manually and take each shot individually.

What you are looking for at the end is a series of photos which captures the full dynamic range of the scene.

A quick tip. It is best to use a tripod and a remote shutter release for this so there is no movement of the scene captured. Although most dedicated HDR software will try and align the images for you this does not always produce super sharp images and can result in degradation of the final image's quality.

Here are three bracketed exposures of a scene below. The three images have the full dynamic range of the scene included.

Midtone Image. The sky is slightly over exposed and the rest of the scene slightly underexposed.

Overexposed Image - 2 stops lighter . The boat and surroundings are correctly exposed but the sky is very overexposed

Underexposed Image - 2 stops darker. The sun is correctly exposed in this image but the rest is very underexposed


Merging


Once you have your photos it is time to merge them together. This requires software of some sort but there are different ways you can do this.

In camera


If your camera has an HDR option it will the merge the photos together immediately after they are taken. I wouldn't advise using this option as there is very little control over how the photos are combined and the results can be disappointing.

Dedicated HDR Software


There are many dedicated software packages out there specifically for merging the photos to HDR such as Photomatix and image processing software such as Photoshop also has an option to do it. This is probably the best option to choose as you get a huge amount of options and flexibility as to how the photos are combined allowing you to craft the finished image to your liking. Moreover, it is a very quick and powerful way of producing HDR images.

Merging Images Manually


Using a raster graphics editor such as Photoshop or GIMP, which allows you to work with multiple layers, you can manually combine the images. By importing the different exposures as separate layers and manually overlaying into one image you can make an HDR image. This technique can give a huge amount of control over how the final image looks but can be very, very time consuming and fidgety.

The 3 images above merged into an HDR image using the Merge to HDR function in Photoshop. The whole scene is now correctly exposed with no large over or under exposed areas.

 

From the Sublime to the Ridiculous

 

Depending on what software you use and how you tweak the settings you can get a range of different images from the same bunch of initial shots. 

Below are three bracketed exposures of a scene:

Midtone Image.
Overexposed Image - 2 1/3 stops lighter
Underexposed Image - 2 1/3 stops darker

Below are various HDR images derived from the three initial shots. I used Photomatix to render all these HDR images and just played around with the settings to get a stronger effect. Which one is better is just a matter of personal preference.


Very subtle use of HDR. Very little difference from the original midtone capture other than the foreground is lighter and more realistically exposed.


Cranking it up. The sky is now darkened and more contrasty whilst the foreground is still well exposed.


Knock it up a notch. The sky darker still with even greater contrast. The background trees are darkened and the foreground is correctly exposed albeit with greater contrast. This is the final image I liked best.


Overdrive. Sky is darker still and the foreground lighter but with extreme contrast across the whole image. Also notice the phenomenon known as Edge Glow appearing where lights and darks juxtapose, such as the large tree.


HDR using 1 photograph


You can get the HDR effect using a single photo. By taking a single photo and producing multiple copies of it at different exposures using software such as Lightroom, you can get the multiple photos needed to pump into the HDR software. Although this works I wouldn't use it as a substitute for taking individual captures of the scene for a number of reasons 

  • You can get a lot of noise when increasing the exposures. 

  • If the image has blown out highlights or completely underexposed areas, the detail from these cannot be recovered.

  • You have to convert to JPEG before putting the images into the HDR software resulting in a loss of quality.

Below is the initial capture. The trees are underexposed and the sky and water is correctly exposed.

The initial shot

Here are the other exposures I created using Lightroom.


1 stop darker using Lightroom

2 stops darker

1 stop lighter

2 stops lighter

And below is the final HDR image created using the 5 images above in Photomatix. I have really cranked up the HDR effect to show how the detail in the darkened areas has been brought out whilst still keeping a good exposure level in the sky and water.


The Final Image. A bit surreal I know but it illustrates the effect which can be achieved from a single image.

 

Don't Stop With HDR Software

 

One final point to mention. Although the HDR software can have a lot of options to control how the images are fused together, often the result might not be quite what you are wanting. But don't fear, there is other software out there that can perform the final touches. There is no reason to stop your image processing with the HDR software. After you get something close to what you want, fire the image into Lightroom or something similar and use that to perform the final tweaks. These software packages give you more power and control over the image than the HDR software does. So instead of expecting your final product to come from the HDR software (as I used to), just see it as another step along the way to creating a great image.

The above image further processed in Lightroom. The trees have been darkened slightly and the colour saturation in them reduced. In addition, the overall contrast has been increased, more so in the sky.

Conclusion


Depending on the software you are using you can get a wide variety of different results from the same set of photos and how you tailor the final image is a matter of personal preference. Personally, I prefer the effect to be quite subtle to try and mirror how it would appear to the human eye, but many prefer a more exaggerated, surrealistic look. 

Don't be put off if you don't get the desired outcome. HDR merging can be a bit of a hit or miss process. Sometimes the images come out great, other times they look awful. Learning to get a good range of exposures and understanding the controls in the software will help but will by no means guarantee a good result everytime. Just keeping plugging away with it and the good images will come.

And that's about it really. This was just a basic introduction to HDR photography. It can get very complex working out the correct exposures to take and how the different merging options in the software work but that is for a later date.

My advice is to have a go. Get out there and take some multiple exposures of a scene, fire them into the software and have a play around. You might be surprised at the results.
