How did I do that? (Part 1 of many to come)

In an effort to bring more visitors to my blog, I will from time to time dispense hints and tips that I use in my photography in a "behind the scenes" manner.

This time I'm showing how I made this HDR.

As you may have read earlier, I took a holiday this year in the Italian region of Switzerland. From time to time I came across really beautiful, photogenic places of worship. When I see really old churches with frescoes, I know that I have to record them using HDR. This was no exception.

It was a really warm day and to get to the church, I had to climb LOTS of steps. For this reason and because of the winding alleys and streets, I decided against taking a tripod with me. I did however, take a mini G-Clamp table top tripod. This little beast which I bought many years ago can be clamped to a ledge, table or shelf or if there are none available, can be stood of a surface thanks to two small support legs. On this occasion, I lay on the floor (to get the perspective I wanted) and mounted the camera using the G-Clamp in its "tripod" mode.

The clamp itself is a bit flimsy so I used the camera in self-timer mode in order not to shake it too much. Ten seconds later, I had three shots of varying brightness which I fed to my HDR programme, the results of which you can see here.

The image can now be seen in Google earth or on Panoramio at full size here.

To my left was an alcove which I also found interesting. For this image, I clamped the G-Clamp to a pew.

HDR has captured the highlights and shadows

The church is "Sta. Maria del Sasso"located in Morcote, Switzerland.

Grossmünster Church Zürich

Had an interesting job last week.

My friend, the Swiss lighting designer Renato M de Toffol has made a new installation in the Grossmünster church in Zürich.

It is programmable according to whatever event is happening in the church and the lighting changes accordingly.

I spent from one thirty in the afternoon until about seven in the evening documenting the different moods available.

The crypt

I photographed everywhere from the crypt to the outside where it is also illuminated.

The pictures will shortly be appearing on his website but in the meantime, I experimented with HDR which was necessary to provide details from the highlights to the shadows.

Here's some of the results.

Dusk is starting outside the church

On my way back to my car, I stopped to take a picture

That's it for now. Thanks for reading

My favourite fourteen

I’ve just been sorting through the images that I took last year in my job as photographer for Regent Lighting here in Switzerland.

I took literally thousands of images and these have now all been categorised, sorted and saved along with their associated backups etc.

I was distracted by reading some of the many “best of” type posts that inevitably appear every year’s end on the ‘net and in print.

With that in mind I decided to choose my favourite images taken in the course of my work last year and remark on a few of them.

All were taken with my Eos 5d. I used my 17 – 40 F4, the 28 – 135 or my 24mm f2.8. The 17 – 40 proved the most popular with the majority taken using that lens.

My work, when I’m on location requires that I reproduce the lighting effects as faithfully as possible. That means no extra lighting. Just me, the camera, a lens and a tripod. Sometimes it’s relatively straightforward such as photographing at dusk of an exterior building lit from out or inside.

These images were all taken using the HDR method of combining three exposures and blending them into one in which details can be seen everywhere.

 Bracketed exposures of 2.5, 1 and 6 seconds. f10

400 ISO. 28 - 135 zoom at 28mm setting.

 Bracketed exposures of 2.5, 1.3 and 5 seconds. f13

400 ISO. 17 - 40 zoom at 17mm setting.

Sometimes however, it gets a tad trickier. I will have to photograph a room where the lights are burning. A “normal” exposure will lead to the lights being “burnt out” on the picture. The same is true if there is a window in the shot, as the daylight can often burn out and look false. This is where HDR again comes to the rescue rendering details in the highlights and shadows.

  Bracketed exposures of 1, 1/2 and 2 seconds. f18

200 ISO. 17 - 40 zoom at 17mm setting

 Bracketed exposures of 1/2, 1/4 and 1 second. f18

400 ISO. 24mm Lens

 Bracketed exposures of 1/2, 1 and 2 seconds. f18

400 ISO. 24mm Lens

  

Bracketed exposures of 1.3, 1.5 and 3 seconds. f13

400 ISO. 17 - 40 at 17 mm setting

  Bracketed exposures of 1/4, 1/2 and 1/8 seconds. f20

125 ISO. 17 - 40 zoom at 17mm setting

Bracketed exposures of 1/5, 1/10 and 2.5 seconds. f18

200 ISO. 17 - 40 zoom at 17mm setting

Lastly there are street scenes which are also helped with the HDR method.

Bracketed exposures of 5, 2.5 and 10 seconds. f13

200 ISO. 28 - 135  zoom at 28mm setting

 

 Bracketed exposures of 2.5, 1.3 and 5 seconds. f10

400 ISO. 28 - 135 zoom at 38mm setting

 Bracketed exposures of 2.5, 1.3 and 5 seconds. f10

400 ISO. 28 - 135 zoom at 28mm setting

 

The only image amongst my favourites for 2010 that wasn’t an HDR is this one.

 Single exposure of 13 seconds. f13

400 ISO. 17 - 40 zoom at 17mm setting

I did make three images but ended up choosing this one as there were enough details already. You can read about the circumstances regarding the taking of this image in a previous blog post here.

All images were taken one of the three lenses mentioned above, normally at the widest setting (in the case of the zooms) with the camera on manual and set to f 10 or above

The 17 – 40 and the 28 – 135 are both nice sharp, contrasty lenses. The only corrections I’ve made are for distortion where the edges of wall etc., are curved. To correct this distortion I use “PT lens” from Tom Niemann. This can be used as a standalone programme or as a plug in for Photoshop. The newer versions of Photoshop have (I believe) this functionality built in. I however am using Photoshop version 7.0. It is a fantastic programme and recognises the camera and lens in use. It then corrects automatically or the user can further refine it. New lenses and Bodies are constantly being added. Take a look. It’s well worth the price.

That's it for now. As usual I appreciate your taking the time to read this and would welcome some comments.

Happy 2011.
