Facing a field of flowers, a photographer has to choose among many possibilities. Here are just a few:

1) He can choose a really beautiful flower and make it the sole point of attraction. In that case, he must decide if the background will be free of any distractions.

2) He can profit from a blurred background that is of a color dramatically opposed to the color of the chosen flower.

3) He might favor an overhead or a low angle shot. As this choice of the angle of view does not apply only to flowers, I found in my archives a low angle shot of a pear tree located in St-Nicolas, Québec. Here it is, so that you can see what kind of effect can be obtained.

4) He can decide to show many flowers on the same picture, considering the interesting impact produced by all the color dots.

5) He might also use the flowers as accessories to direct the eye of the viewer to another point of interest like, for example, a building with special architectural characteristics.

The flowers and the bumblebee are two interesting subjects; they complement each other in this picture. It would be hard for me to decide which one I prefer.

Unless there is no other possibility, it is better to avoid shooting flowers under full sun as there will be considerable reflection on their petals. If you have no choice, use a polarizing filter, well adjusted, to reduce the undesirable effects of direct sunlight.

The ideal day to get out and take pictures of flowers is a day without wind, where there is a bright light but dimmed by an overcast sky.

The quality of colors and contrasts will be maximized if the pictures are taken during the morning or at the end of the afternoon.

Aperture has a definite impact on the final result. With a wide aperture (smaller numbers like F2.8 or F4.0) you will get a sharp subject with everything blurred around it. This will make your flower stand out. With a small aperture (bigger numbers like F14, F16), both foreground and background will be sharper, with an even better result using a wide-angle lens. Your flower will lose a bit of its impact as all the elements in the picture will now shine. Below is a picture taken in Ontario, during the Ottawa Tulip Festival.

1) Remove any dirt from the plant you want to capture and choose a plant whose petals are in perfect condition.

2) Use a tripod, a remote control release and the mirror lock-up (MLU) function for better results.

3) The camera should ideally be used with manual focus, for improved sharpness. In order to verify if the picture will be in focus, look at the LCD screen and enlarge the picture (5X or 10X). You will immediately see if a minor adjustment is needed to get a sharp photo or to improve the depth-of-field.

The histogram should be checked upon taking the picture to immediately compensate for the necessary amount of light.

You can use a flash to reduce aperture. You must adjust it so that it’s not shooting at full power otherwise there will be too much reflection and you will lose all the delicate nuances of colors and contrasts.

A method that will produce surprising results is called “zoom burst”. You slowly move the zoom of a lens on all its focal length while the shutter remains open during the process. You must select a speed that is slow enough to accommodate the full deflection of the zoom. You should know that many shots are normally needed before you get a satisfying image.

Every lens offers different possibilities:

1) The macro lens is useful if you wish to capture very precise details on the flower. To add an interesting effect, you can even spray the flower lightly with water so that a few droplets remain on the petals.

2) The wide-angle lens allows you to transform an image and give it an original perspective. The effect will be more important if you shoot the flower from a special angle like, for example, from the ground up. If you must lie on the ground, use a little carpet to keep yourself clean and dry. I bought a right-angle finder to ease the workload when shooting under complicated angles. This could be a potentially interesting addition to your equipment.

3) Finally, the telephoto allows you to pick a particular flower and, because of compressed perspective, offers you a background filled with multiple colors.

Let’s end this section with a mushroom picture. The same principles apply with regards to simplicity, settings and angles of views. I could have chosen to show only an oversize shot of a mushroom, or take only part of it, but I preferred an approach that would allow me to show the radically different shapes of the specimens found at the Laurentian Forestry Center in Québec.

Night Photography

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.

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.

Aperture, ISO and Speed

A Decision Has to be Taken

You must decide the ideal combination between the following: aperture, speed and ISO. All three are interrelated and choosing one has a direct influence on the other two.

You are facing a beautiful landscape in which you want everything to be in focus: you decide that the aperture is what matters the most. Choosing aperture as the priority is a very popular choice. Let’s consider that you choose F16, which should give you a very interesting depth-of-field but will demand a lot of light. You have to compensate somewhere. If there is not much movement in the scene, and you have access to a tripod, you might decide to choose a slow speed, which allows more time for the light to enter the camera. Doing so, you won’t need to crank the ISO and you will avoid adding useless noise to your picture.

In the picture below, aperture is set at F16. The vegetation in the left corner draws the viewer’s eye toward the pedestrians, and then progressively to the quai des Cageux. We finally see the Quebec bridge, the longest cantilever bridge in the world.

If you decide that speed is a priority, you will have to compromise ISO or aperture. ISO will have to be increased to improve light sensibility, but doing so will increase the size of the grain in the picture. Depth-of-field will have to be adjusted as well since a higher speed does not let much light enter the camera. You won’t be able to pick F16 this time. So you will eventually find that there are some out of focus areas in your picture. With a bit of practice, you can be less demanding on the speed, providing you can follow the subject with your camera (it is like if you were slowing down the subject, so less speed is required).

The picture below was a bit particular: it was taken when I was on a boat rocked by waves. The eagle was far away and was traveling in the opposite direction, thus increasing the relative speed of the subject. The Canon 5D MKII was hand held and 400mm focal was necessary. Speed was crancked at 1/1600 and the ISO required was set at 5000. Naturally, the grain in the picture being larger, slightly diminishes the quality. This was a necessary compromise if the eagle was to be taken in flight.

It is getting dark and you want a photo with absolutely no noise and you decide that the aperture is what matters the most. You make no compromise and choose ISO 50. This setting requires a lot of light, because the lower the ISO, the higher the demand for light. In order to make sure that your picture will not be blurred, a tripod will be necessary, since there will be an extended exposition time. In the picture below, the shutter has been opened for ten seconds, with a 9.0 aperture, 200mm focal and 50 ISO. Only the small branches in the foreground are blurred.

Note: in general, it is better to use a tripod as often as possible, even in daylight, in order to optimize quality. Choose a heavy enough tripod to prevent vibrations under windy conditions. A light tripod is easy to carry but does not allow for acceptable pictures in adverse weather. It’s obvious that this Queen Mary II photo would not have been as precise if a light tripod had been used. In this case, it would have meant that continual vibrations would have been recorded during 10 seconds. The boat would have been totally blurred.
