Using a zoom lens

A Summer morning gave me another chance to grab my versatile 18-135 mm f/3,5-5,6 zoom lens and Canon DSLR show you the possibilities when using a zoom lens. The weather was bright sunshine which presents some issues but makes a walk in the garden very enjoyable. The flowers, leaves, insects, the reflections on the pond were the ideal environment to get great photos and a source of inspiration. In this post I just want to show you the impact of using a zoom lens on the composition of the image.

The context

The above panorama shows the context. There is a path that goes all the way around the pond, with bridges at both ends. The view is particularly captivating from the bridges. But it is also beautiful from all sides. This means that people are often in the frame and can be a distraction from the natural beauty. Using a zoom lens, and patience, will allow you to capture the images when there are few or no people in the frame.

Above you can see people on the bridge and on the right hand side. The person in red, under the weeping willow tree, is the most bothersome as red really catches your attention.

First, whenever possible, set the ISO on your camera to 100, as I did here. This will reduce any potential for noise in the final image. Noise being a grainy aspect to the photograph.

Three examples

Here are 3 photographs from the bridge at the eastern bridge. They were taken with focal lengths set to 22mm, 56mm and 76mm.

If we compare these to the panorama we can see that the higher the focal length is the less we can appreciate the length of the pond. Distances are compressed. This is where the artist in you will decide the right balance between keeping the depth of field in the image, zooming to remove distractions, and focusing on details.

Clearly if the bridge is the subject of the photo the more you zoom the more of the bridge you will see. It is hardly visible at 22mm. But if you are taking a photo of a water lily pond, then 22mm really shows the pond in its surroundings.

My favourite here is the 56mm. Why, because it takes the gentlemen on the right out of the frame, it keeps the blue sky, the impression of a pond. The reflection on the waters surface of the sky is less overpowering.

Zooming even more

Changing the objective on my camera to allow me to zoom to 250mm allows me to focus on individual items in and around the pond. Here is a of 2 while lilies amongst their leaves. There are several insects in and around the flowers. If you look carefully there is a turquoise dragon fly just a short distance above the left lily.

I did another post on zooming earlier in the year which you can find here.

Capturing birds in flight

Estimated Reading Time: 4 minutes

My afternoon introduction to capturing birds in flight tool place at the Étang de la Galiotte. This translates to Galiotte Pond. When you visit you will see that is an understated way of describing a large mass of water in Carrières-sous-Poissy. Capturing birds in flight professionally requires specialized equipment. I need to verify that I am interested enough to make that investment. So with my existing equipment I see about capturing birds in flight.

You can see from the map the lake is quite large. The town of Carrières-sous-Poissy, which translates to Quarries under Poissy, gives a good clue to the origin of the Étang de la Galiotte. The Paris region is made up of layers of sand, limestone, mixed with various amounts of clay. Being by the river Seine transport of the quarried sand was easy. Subsequently the Étang de la Galiotte was filled with river water to make a lake.

The lake is a major feature of the new park du peuple de l’herbe which covers 113 hectares.

Today, the lake and surrounding park are the host of birds, fish and people. There is a small island in the centre to help birds nest and breed. Making it a good site for capturing birds in flight. This protected natural space hosts a village of about 30 floating homes on the southern shore of the lake. There is an active residents association.

The Yvelines region published a detailed study, in French, about steps taken to avoid the risks associated to natural disasters in the region linked to the river, the geology and other potential threats.

Now to my visit. What did I see and how did the afternoon go?

Getting There

First of all if you arrive from Paris take to the train or RER to Poissy. You can walk from the train station at Poissy. It’s a fairly level walk over the main road bridge. It will take 20 minutes, about 1.5km. If you arrive by car, then I suggest you park in the Parking du parc du peuple de l’herbe. There are several bus services which use the road bridge to get to the Poissy station. The town of Poissy has also a project to build a new footbridge (site in French) linking the station to the park.

For the less nimble on their feet, I would recommend sticking to the path that run along the river Seine, rather than those by the lake which end up as a narrow track in the woods.

Bright sunshine and water

Bright sunshine can make photography complicated. On the good side everything is brightly lit, but with that comes shadows. And the contrast can be hard to manage. Add to that water, and to a slightly lesser degree the bright blue sky, and you have bright reflections and dispersed light from the sky and water. This can make the blue sky appear grey, the beautiful water dull and opaque.

Polarization

The solution to this is a polarizing filter. You may will be familiar with polarizing sun glasses. The same filter on your objective will filter out light which is dispersed in all directions. It will leave nicely aligned light rays. The advantage that the filter has over sunglasses is that you can spin the filter to choose exactly which direction the light rays should be. This allows you to choose the blue colour for your sky and optimize the view of the water so you can see the fish etc. Unfortunately my filter was not with me on this trip.

Freezing motion

So I chose to focus on the bird-life. In June the young ducks and geese still look cute and fluffy. They become a natural subject for cute photos. There are also plenty of terns here. They fly quickly over the water’s surface before diving into the water to capture fish. And the fish don’t have much chance as they are so fast. This speed also makes them difficult to photograph.

Some starting steps

Time needed: 30 minutes

Capturing flying birds

  1. Before you go

    Empty the memory card, and take the fastest card you have. It might be worth checking what file types you are storing. In general I write RAW and JPEG files to the card. Doing this means writing takes longer and uses more space. You could just save high quality JPEG for this session.

  2. Select objective

    Use a zoom, I would say at least 135mm, preferably 210mm, or more

  3. Use auto-focus

    Set the auto focus to AI servo. You will not be able to focus manually on the fast moving birds, use the camera’s intelligence o track them in flight

  4. Choose the ISO setting

    Consider setting the ISO to 100, or 200, depending on the aperture of your objective. The smaller the aperture the less light will be collected and therefore a higher ISO can help.

  5. Set speed

    In order to freeze the movement of a bird, or anything moving rapidly, set the speed to a maximum of 1/800s

  6. Review and modify

    After your first series of photos review and adjust the settings. Too dark check the ISO and aperture. Blurred reduce the speed.

  7. Repeat

    There will be many missed shots so just keep going

SD Card speeds

There are many sizes of SD cards, but I would suggest 32GB or 64GB. Which gives plenty of room and not a totally unmanageable volumes of photos to sort through when you get home. When the technology was launched it supported a 12.5 MB/s speed. At this speed it would take 2 seconds to write a typical RAW image. Making continuous shooting for a bird in flight impossible. The technology now supports up to 3940MB/s however not all cameras support such speeds, nor do they need them. There are 3 common ways of describing the speed that the card can transfer data.

Look for card with the U3 class. These can support up to 30 MB/s which id ample for video and photo recording. There is more information on the classes on the SD card Association website.

Good luck capturing birds in flight. If you further inspiration try this external website.

Return visit

It’s a great park and I went back in the winter. You can read about it here.

I have other posts about my visits along the River Seine, for example Spring walk along the Seine

Catch them while you can

Poppies flower for a short time, you need to catch them while you can. They are short-lived perennial plants and have brightly coloured flowers. The petals appear crumpled and very fine. Spreading out as they straighten. There are many species and many colours. The one I see most, is the 4 petaled red poppy. It grows in and around farmer’s fields of wheat, corn and barley. I expect it’s the Papaver rhoeas, or common poppy I see most. I think it’s this one because of the name and its description. It has 4 red petals. The other famous poppy is the Papaver somniferum, commonly known as the opium poppy. This one I never see. The common poppy will flower from late spring to early summer but each flower doesn’t last long so catch them while you can.

It’s hard to imagine how soldiers in the battlefields of the first world war would look upon such a field of poppies. But the poppy fields of Belgium became a symbol of the conflict and feature in a poem from the front line – In Flanders Fields by John McCrae.

Remembrance

The poppy maintains that link today as the symbol of remembrance for the Commonwealth Remembrance Day. This is held annually on November 11th. It marks the end of First World War hostilities. In the UK the date is an important fund raising event for veterans and organised by the The Royal British Legion. The poppy is not the only flower associated with the end of World War 1. In France it is the cornflower, which is often found growing next to poppies.
