A Sat Airlines aircraft is on final for the Peyresourde mountain airfield
Flight simulation allows the use of all company liveries and types of aircraft. In the present case, a DHC-8-227Q from Sat Airlines, with the Sakhalin Energy logo, has mysteriously found itself inbound for the Peyresourde mountain airfield.

Peyresourde Balestas is located in the Pyrenees, at an altitude of 1580 meters. Its runway is only 335 meters long and has a 15 degree slope. The beginning of the James Bond movie “Tomorrow never dies” has been filmed there. The runway is long enough to accommodate the DHC-8-227Q as the plane’s excellent braking capacity is even improved by the sloped runway. If you touch early enough, you won’t even have to apply full braking power.

A Dash 7, with its superb ability to operate from any kind of field, would also fit in there, providing the amount of fuel and cargo is well calculated. Because what lands must also takeoff.

The Peyresourde Balestas mountain airfield is made by LLH Créations, from France. The company has already produced four mountain airfields located in the French Alps. This is the first one in the Pyrenees.
Virtualcol FS Software created the Dash-8 used for this flight. For a very reasonable price, that company offers, in one bundle, an astonishing amount of liveries and all the types of DHC-8. Their product is detailed enough and really takes lower end computers into account when it comes to FPS (frames per second). Don’t expect the same realism as with the Q400 from Majestic Software though: Majestic’s Q400 is on a category by itself in the sim world and the price is adjusted accordingly.
The fun will not be over after you land. You will find that the takeoff is quite spectacular. Apply the brakes, full power and the necessary amount of flaps and let it go! You’ll see that the runway’s end is coming quickly and that you’re building speed like you never believed possible with a Dash 8!

1. A picture you would never have thought possible, because of extreme contrasts between brightness and darkness, is now accessible to you through HDR.
2. For a good HDR picture, you need at least 1) an interesting subject 2) an appropriate setting or background 3) the appropriate light and 4) a wide range in contrasts. That seems basic, but HDR will not save a picture that was not thought through.
3. You need a software like Photomatix, to transform several pictures taken at different exposures into one HDR picture. But this is only the first step. You will also need another editing software to improve the general result after Photomatix has been used.
4. A tripod is required to help Photomatix align the pictures and create the HDR effect.
5. As with your normal pictures, it is always better to try to use the lowest ISO as possible.
Gruyères, Switzerland, 2013.
6. It is safer to work with manual focus. This way, none of your shots will have been influenced by external objects without you noticing. It will always be the exact same focus throughout the HDR photo session. With automatic focus, you generally notice your blurred pictures when you’re back home and then it is too late (it will often happen under low light conditions).
7. The greater the contrast, the more exposures you need to take (up to nine) in order to match the dynamic range of your eyes.
8. The idea is to take each exposure at a different exposure setting. If you need seven exposures, an example of settings would be: -1, -2/3, -1/3, 0, +1/3, +2/3, +1. You might decide that three exposures only are necessary and go for -2, 0, +2 or -1, 0, +1. The choice is yours but you must take only the required number of exposures to avoid including too much noise in your shots.

9. Throughout your HDR exposures of a specific scene, always keep the same aperture.
10. A scene is rarely perfectly balanced with light and shadows. If there are many shadow areas in the photo you want to take, then take more exposures over the recommended settings to ensure that you caught the whole dynamic range of the scene.
A house in Sainte-Pétronille, on Île d’Orléans, autumn 2012. HDR picture.
11. Inversely, if your scene has lots of highlight areas, take more exposures under the recommended settings.
12. Setting your camera to “automatic bracketing” is preferable because all the pictures are taken quickly thus avoiding to show any blurred picture in the final HDR picture. But if you want to show the movement of water in a creek, you don’t need bracketing: just take few shots with different time of exposure (in number of seconds). Just don’t overdo it otherwise it will give place to an uninteresting undefined white surface.
13. Check your LCD monitor so that none of the highlights are blown out. There would be a loss of details. For the same reason, you must avoid to block the shadows.
14. Always work with RAW files, it gives you better results. The RAW file already provides you with more f/stops then the JPEG file, and this before the transformation in HDR has even started).
15. Of all the lenses I’m using, the wide angle lens is my preferred one with it comes to HDR photography.

16. To improve the composition or enhance the general impact, crop the picture.
17. Not all pictures are appropriate for HDR transformation. If you want a dramatic silhouette as the final result, for example, HDR will not be appropriate. It will reveal too many details in the shadows and you will lose the high contrast effect that you were looking for. With practice, you will recognize where HDR is the most effective.
18. Whether you want a realistic picture or not, you can obtain surprising results with the combined effects of softwares like Photomatix, Topaz, Photoshop, Nik Software, Lightroom, Lucis Pro and so on. It’s only a matter of taking your time to experiment.
19. If you have only one picture on hand, like a shot you took years ago, and you would like to give it an HDR effect, you can use a software likeTopaz Adjust. There is an HDR effect section in that software that allows you to get a wide range of effects. But this is not going to be nearly as good as the real HDR resulting out of many pictures. The final editing step is, most of the time, done using Photoshop.
20. An unpretentious book about HDR is “Rick Sammon’s HDR Photography Secrets for Digital Photographers”. It is simple, colorful, well written and loaded with practical informations.

Cumuliform clouds add energy to any photo. Even photos in black and white benefit from them largely, whether it is for a normal or an HDR photo.

The stratiform clouds add to the tranquillity and the stability of a photo.
Daytona Beach under stratus clouds in 2011. The end of the afternoon allows the fresh air from the sea to move over the heated land, which helps create few cumulus fractus, visible near the buildings.
Clouds including a stratiform and cumuliform components (stratocumulus) produce an effect that is more energizing than the simple stratus, while avoiding the explosion of energy of the cumuliform clouds.
A stratocumulus adds to this otherwise peaceful scenery captured on board the Lyria train between Paris and Geneva in 2013.
The cold front
The approach of a cold front enhances the possibility of interesting photos. If it is a fast moving cold front of moist and unstable air, the photos will probably be more spectacular, as some thunderstorms will be associated with the system. A dew point of more than 15 C indicates the presence of a lot of water vapor which can be transformed into precipitation, thus releasing a lot of energy. When these conditions are combined with a really strong contrast between the new air mass which approaches and the one which goes away, the produced meteorological phenomena will certainly be intense.
In the photos below, the meteorological system approaching the Quebec Jean-Lesage international airport also had to cross a small mountain range.

The morning fog
The morning fog offers many opportunities for interesting photos. You can choose an isolated tree and capture the combined effects of the morning sun and fog. Or you may choose a cluster of trees, for a completely different effect. Both photos below were taken in Domaine Cataraqui, Quebec City.
Trees in fog at Domaine Cataraqui, Quebec City 2009
Sun and fog provide for a special atmosphere at the Domaine Cataraqui, Quebec City 2009
A morning fog resulting from a cold cloudless night will persist for hours if there is no wind. The cold morning air, motionless over a slightly hotter stretch of water, creates a fog that will finally disappear just before noon, when the atmosphere has been heated enough. If there had been an overcast sky during the night, chances are that the air over the water would have remained at a higher temperature, preventing the formation of fog.
The opportunities for more interesting photos arise when you witness the first holes in the fog layer.
The Ocean tugboats during a dense fog in the Bassin Louise in Quebec (2012).
We can take into account the season to estimate the speed of the diurnal reheating of the lower atmosphere. A morning fog will need more time to dissipate from late autumn to early spring: that leaves more time for the photographer to prepare. The forecasts can announce the disappearance of fog while it will not be the case if, over your sector, there is an invading layer of stratocumulus preventing the morning sun from reaching the ground.
To determine if the fog is going to dissipate as expected or will remain and possibly intensify, watch the difference between the temperature and the dew point on the hourly meteorological observations issued by weather stations near your place of residence. If the temperature and dew point spread increases, the fog is going to lift. If the difference between those two decreases, the fog is going to persist and possibly intensify.
The mist
The mist can be qualified as such when the visibility is superior to ½ mile, but do not exceed 6 miles for an observer on the ground. If the visibility is of ½ mile or less, it is called fog. This photo of the Bic National Park, near Rimouski, shows the interesting effect that the mist adds to a beautiful landscape.
Mist in the Bic National Park, Province of Quebec (2009)
Hot and unstable air in winter
When there is a warm and unstable air advection (about 0 degrees) while winter has already settled, there are good opportunities for photos. A moderately developed cumulus produces significant snow showers and this snow sticks on all the surrounding objects. All that snow would have begun to melt on contact of objects if the latter had had a temperature superior to zero degree. But, the winter being already settled, the snow persists. It gives enough time to capture some souvenirs.

The local effects
A photographer might benefit from learning about the meteorological local effects influencing the regions he intends to visit. The local effects are often simple to understand and they repeat themselves regularly, according to wind and season changes. The knowledge of these effects allows the photographer to be ready and position himself even before the phenomenon occurs. It limits the comments like: “If I had known that it would occur, I would have settled down here one hour earlier!“
The local terrain as well as large size bodies of water produce predictable meteorological phenomenon that can be used by a well prepared photographer. It can consist of persistent fog, repetitive snowstorms over a small sector, strong winds, cumuliform clouds alongside the mountain summits, etc. By being positioned at the right place, at the right time, the desired photo can be realized.
A change in the wind direction
A change in the wind direction suddenly increases the opportunities of interesting photos. It might announce the approach of a cold front, a warm front, a sea or land breeze, etc. In the photo below, a bit of fresher air suddenly began crossing the St-Lawrence seaway at the end of the day, thanks to the approach of a weak cold front. The water was still relatively warm and the moisture which was present over the surface became visible due to the cool air supply. The conditions were now ideal for a short-term thin fog, as long as the wind speed would not increase. Just in time for a photo.

Familiarization with weather radars
It can be useful to get acquainted with weather radars which, for the needs of photography, remain simple to interpret. Multiple echoes of small dimension with a steep gradient of various colors indicate precipitation resulting from cumuliform clouds. The showers associated with these clouds are often moderated or strong and will be the result of approaching towering cumulus or cumulonimbus (thunderstorms). A towering cumulus presents a dark base and a white summit to the photographer. At sunset, their vertical development can be used to emphasize the last rays of light.
The side of a towering cumulus (TCU) is benefiting from the remaining sunlight over Quebec
Large echo areas of similar colors of low intensity indicate a relatively stable air generally producing steady light rain or drizzle. This should be understood as a possibility of increased humidity limiting the visibility through mist or fog.
Hoar frost
Hoar frost is a short-term phenomenon. It is thus necessary to capture the scene before the sun melts everything. The photo below shows some small twigs on which hoar frost has settled. It was taken at the beginning of the seventies. Although the quality of the photo is not exceptional, the meteorological phenomenon is well demonstrated.

Forest fires
Wishing to make photos of western Canada during summer 2014, I came up against a season where hundreds of forest fires were raging. The smoke was covering some parts of Alberta and British Columbia. Some fires were important enough to require the closure of the sole highway connecting Lake Louise to Jasper. I thus decided to include the effects of those fires in the holiday souvenirs.
A visibility reduced in forest fire smoke allows a photographer to obtain, without special editing, sunsets with interesting colors.

The smoke also produces an effect similar as fog, but a fog which would be impossible to obtain at the end of a summer afternoon while the sun shines and there is a 38 degrees Celsius temperature.

1. Ensure you bring : tripod, remote cable, flashlight and timer.
2. Use of RAW (.TIFF) is highly recommended. There is a greater potential for corrections afterward, if something is not according to your taste.
3. Noise reduction activated on the camera.
4. If the winds are calm: ISO between 50 and 200.
5. If there are strong winds: ISO 400 might be useful to avoid a blurred picture caused by the continual small vibrations of the tripod due to a long exposure. That is why a heavy tripod is always preferable.

6. If you wish to take a picture of people moving at a normal pace, and you have access to quality lenses, it will often be necessary to use ISO 800 to get a clear shot. This setting could allow the shutter speed to be adjusted at about 1/200 which is plenty to obtain a picture that is not blurred; that is unless you are not using a long focal like 200mm or more.
7. For people shots, it is better to have your back to the remaining light on the horizon, unless your goal is to capture a silhouette.
8. For extended exposure, use the autofocus “one shot” setting until it stops working due to insufficient light. Then use manual focus. Or use manual focus all along, with Liveview, if you prefer it that way, for extra precision.
9. Mirror lock-up function must be activated to avoid vibrations caused by the shutter action.
10. Use a remote cable when taking the picture to avoid useless vibrations.

11. If you wish, you might think of selecting a specific AF point to ensure a better focus if there is a small area that matters the most to you in the picture.
12. Do not use the FULL AUTO mode during night photography.
13. The three most important modes are 1. Aperture (taking care of slightly overexposing for surrounding lights) 2. Speed 3. Manual. There is one more reason to overexpose a bit if you work with the RAW format: there is more data information in light than in shadow, so once the picture is taken you have access to more data to play with to adjust the dark sections of the picture.
14. If you expect an exposure longer than 30 seconds, use BULB mode.
15. Night pictures are best taken using the camera bracketing funtion (-1,0,+1) and this, every two minutes.
A Christmas tree in Sillery
16. The best period for night shots is 15 minutes after sunset, until official night time, which you can find on the internet. As this period is quite short, it is important that you know in advance what is of interest to you and where you will position yourself when comes the time for the picture.
17. Total darkness is not what is the most favourable in night photography. But you can certainly obtain interesting results using black and white.
18. Beware of surrounding light reflection in your lens.
19. Histogram has to be reviewed to ensure that there is no serious overexposure.
20. It is preferable to choose an aperture between F11 and F16 for maximum sharpness as well as an adequate depth-of-field.
21. If shooting a subject against the remaining light over the horizon, there might be quite a contrast in lighting between where you stand and where your subject is positioned. You might think of using grad filters (3-6-9-10) to help correct this huge light difference, or you can transform the standard photo session into an HDR one. Or both! There are also filters specifically designed for sunrise and sunset periods that can improve your shots.
View from our hotel room in Schwanden, Switzerland 2013
Here are some of the pictures recently added to the Europe photo gallery. Schwanden, in Switzerland, was a superb discovery as the hotel was in the countryside but at a very reasonable distance from a big city like Bernes. This is an HDR picture, as the contrasts were just too important between the shadows under the balcony and the natural light of the sky. The Schwanden picture represents in fact five shots each taken with a different exposure. Photomatix is the software used to mix together all the pictures. Have a good visit in the photo galleries!
This book is about the daily operations and lifestyle of the people who worked at decoding German messages in Bletchley Park, England, during the Second World War. The reader quickly realizes the incredible impact of the shadow workers on major battles like the Battle of England, El Alamein or eventually the D-Day. Moreover, it allows the reader to enter the Park’s installations to witness the rigor and professionalism of the men and women who worked day and night, through high tension and exhaustion, to accomplish their duties.
The Secret Life of Bletchley Park
Their efforts to obtain results bordered with obsession. Even while sleeping, brains were at work. A major breakthrough happened after a researcher woke up in the middle of the night with a long awaited solution. Naturally, names like Alan Turing, John Herivel or Dillwyn Knox are repeated on a regular basis. But they are just a few in a crowd who played an essential role.
Bletchley Park was highly efficient for many reasons:
1. A wise combination of employees with diversified training and capabilities. A wide cross-section of abilities and general culture were sought after. Women and men working at decoding were gifted with a highly superior intelligence and focusing capacity. Multiple fields of knowledge were required: there were experts in mathematics as much as in history, classical letters or linguistic. Dillwyn Knox, one of the Bletchley stars, was himself an expert in old papyrus. The combination of intelligence resulted in important innovation.
2. The ability to keep a secret: the employees were scrupulously screened and could not walk in any other buildings than the one that they were assigned for their work. If there had been a mole in one of the buildings, that person would not have been able to have a physical access to other buildings to try to acquire secret information. A common goal and a deep understanding about the importance of their sole objective helped the staff to deal with fatigue and keep the unavoidable personal conflicts under control. The discretion about the operations at Bletchley was even maintained by the employees after the war was officially over.
3. A special treatment for the code breakers: even if Bletchley Park was officially created for military purposes, there was no strict military regime implemented: [my translation] “Throughout the years and centuries, we observe that British intelligence is partly a military affair, but is mostly managed by talented civilians”. The code breakers needed a special treatment: [my translation] “It was deemed very important that the “experts” benefitted from enough space and liberty so that their brilliant thinking could be used at its full potential”. They did not have to deal with restrictions and discipline applied to other employees. This objective to avoid useless pressure on highly skilled employees has been repeated in successful international companies aimed at innovation.
4. Collaboration between countries: it is important to mention the essential collaboration between Poland, England and France at gathering results aimed at cracking the Enigma code. Up to the moment that France was defeated, all the found solutions were shared. Besides, Polish cryptanalysts where the first to decipher the codes on the first version of the Enigma machine, results that were shared with the two other countries.
5. The importance of the chance factor in the success of the operations: the chance factor would eventually play a key role in the ability for Bletchley Park to maintain its operations for a prolonged period. In spite of the intense German bombings, very little damage was inflicted to the buildings where the code breakers were working: [my translation] “We owe it to a miracle that only two bombs fell on Bletchley Park […]. Moreover, another bomb fell near the site where Knox and Lever were working, but it never exploded”. Furthermore, two other bombs fell on the Park, also without exploding.
There were nonetheless obstacles to efficient operations. These included the existence of useless levels of administration: primary information starts to be transformed as soon as it is passed to another level for interpretation. The more levels there are, the more the message is transformed. Some people become masters at protecting their own status and job and eventually become superfluous. Because of their higher status, they are harder to dislodge. This situation could not be avoided at Bletchley Park: [my translation] “Our working place is actually overcrowded by intelligence officers who mishandle our results and make no efforts to double check their arbitrary correction”.
A book passage that particularly touched me was the story of three British sailors who swam up to a slowly sinking U-Boat, the U-559, and helped protect and bring back a four rotor Enigma machine (the most complex version) as well as all the Stark keys used with the machine. The two sailors who entered the U-Boat drowned as they had insufficient time to get out on time. The third sailor, who had stayed outside, was able to bring back all the secret material (wisely placed in a sealed bag) to his ship. To get a hold of this Enigma machine and all its keys would be deemed of capital importance to help neutralize the German forces on the oceans.
I conclude with a quote from Mavis Batey which resumes quite well the state of mind of the people who worked at Bletchley Park: [my translation] “You do things or not, but if you don’t act, nobody will do it at your place”.
Bilingual readers who appreciate real life stories about the sea will love: “On l’appelait Bugaled Breizh”. This is the story of a trawler that sinks with all crew and equipment, while fishing in the Cornouailles region. Experienced sailors were on board and the weather was fair. Other trawlers were present in the area and their captains were maintaining contact with each other by radio. Suddenly, the Bugaled Breizh’s captain mayday call was received. Just a few words, not even enough time to complete his sentence.
Yann Queffélec – On l’appelait Bugaled Breizh
We soon discover that the trawlers were not alone in the area. There were alsonuclear submarines on an exercise in shallow waters. And there is a possibility that a submarine from an uninvited country could have also been watching the manoeuvers, well protected in the obscurity and silence.
The book raises the possibility that a fast moving submarine could have been entangled in the Bugaled Breizh’s fishing net, thus destabilizing the trawler and sinking it, without giving the captain any time to react. As for keeping the truth hidden about the accident,it is believed that if the facts were openly revealed to the general public, it would create strong political tensions due to admitting that an undetectedsubmarine was closely watching the military exercise. The book enumerates possible reasons explaining the presence of the foreign submarine in the area.
Theenquiry, or shall I say inquiries, have been stalled for over ten years now. But as questions have been asked over the years to a vast network of interested parties, a better idea of what could have been the causes behind that drama has emerged.
This is a really interesting book, signed by the reknowned writer Yann Queffélec (Goncourt prize 1985 for Les Noces barbares) also helped by Pascal Bodéré, a journalist known as one of the best connaisseur of the Bugaled Breizh affair.
1978. During my first trip to Europe , I am lucky enough to capture this picture of Concorde at Charles de Gaulle Airport , France, from the window of the Air Canada Boeing B-747 that flew us over the Atlantic. The arrival was punctuated by a missed approach due to adverse weather conditions.
1980. I fulfill my dream to fly a plane and sign-up for a private pilot course in St- Jean -sur- Richelieu. My first solo flight , which means without an instructor, takes place on a Grumman Cheetah (C-GVXO) on a sunny day. The landing is smooth and I can’t believe I will finally be able to fly unaccompanied. A dream come true !
As the private pilot course continues, a change in aircraft model is required to practice incipient spins because the Cheetah does not meet the criterias required by flight schools. If we would find ourselves in a complete spin during the exercise, it would take too long to correct. So a Cessna C-150 (C-GGNK) will be used . The transition is strange as students have to suddenly enter a whole new aircraft for this exercise only. Feelings and views are completely different.

All instructors do not have the same luck, one of them and his student eventually experience a real engine failure during take-off on their Cessna C-150. Fortunately, no one is killed or injured . However , the damage is considerable. The photo below shows what is left of the plane.
