Train layout photography

09/05/2006 Train layout photography
Some people have asked how I produce such nice sharp images of my train layout so I thought I would describe the techniques that I use.

Camera selection
I use a digital camera, currently a Nikon Coolpix 5000 which produces 5 megapixel images. 5 MP is way more than what is needed for images for the web and I usually reduce the size and resolution before posting on my web pages.

Here is what is important.

Minimum focus distance. Thankfully, many digital cameras now have excellent minimum focus ranges such as 2 to 5cm
Ability to select aperture priority mode. The camera must be able to let you select the aperture. This is important for controlling depth of field.
A self timer. This lets you set a delay before the camera takes the picture.
A fold out viewfinder is nice to have.
Ability to switch the flash unit off.
The smaller the camera the better, as it is easier to place a small camera on the layout itself.

Lighting
Switch the flash unit of the camera OFF. The flash is usually way too intense for close up work and the camera does not have enough time to react and end the exposure before everything in the foreground is burnt out (over exposed)
Try to get as much constant lighting onto the subject as possible, but having said that, the lighting should resemble the real world as much as possible, so do not create the illusion of 4 suns in the sky by having 4 lamps at different positions, producing 4 shadows for every object!
Do not put intense lamps near the models as they may simply get melted. You do not need a huge amount of light anyway as you will see.

Depth of field
Depth of field is the area that is in focus. The smaller the aperture the more depth of field you will get. Small apertures have the larger numbers, such as F8, f11, f22. The closer the subject is to the lens, the smaller the depth of field. Since we are photographing tiny models, we generally have to be very close to the subject and that is why it is critical to compensate by using as small an aperture as possible.

Small apertures however reduce the light getting through the lens, so in order to get enough light we need as much light as possible or we increase the duration of the exposure, or both. Once you have maximized the amount of light using reasonable means, such as room lighting or positioning an additional light in place, the rest is done by long exposures.

Positioning the camera
Since we need fairly long time exposures, we have to ensure that the camera is still during the exposure. This rules out hand holding. You could use a tripod, but that limits you to scenes near the edge of the layout. You can also get very small tripods that can be placed on the layout as well but this is not very practical. What is practical is a very small beanbag and or a couple of small wedges that can be placed under the camera in order to direct the lens in whatever direction you need. This is where a viewfinder that can swivel comes in handy.

Positioning the camera right inside or on the layout produces a point of view that closely matches what a person on the landscape would see. The closer you can get the center of the lens to the ground the better.

Taking the picture

Place the camera on the layout. You may be limited to space on the tracks (take care the camera does not short out the tracks if the layout has to be powered up) or on a road or in a field.

Set the camera to its macro mode if it has one, and its minimum focus.
Set it to the minimum aperture (select aperture priority often marked 'A' and the highest f number f8, f11, f22)
Set the camera to use the self timer
Position the camera using the wedges or beanbag to frame the picture. Watch out for distracting things in the background such as windows, wall lights etc. Ensure the camera itself is not shading the subject
Press the shutter release and then step away so that you are not shading the subject area

By using the self timer, you reduce the vibration and movement of the camera that results from your finger pressing the shutter release. It is even better than a mechanical remote shutter release. Some high end cameras have an infra red remote release which would also work well.

The exposure may take 20 or 30 seconds. It needs all that time to get enough light in through the small aperture.

Movement
The long exposure times make it very easy to simulate train movement. Once the exposure has started, simply move the train either by hand or with a locomotive. It does not have to move very fast or far...

Some examples

First, not what to do... taking a picture from a bird's eye view does not produce a view with which most of us are familiar..

This looks unsettling for those of us who do not spend much time up in the air. Even a pilot may feel a little uneasy going down at this angle towards mountains. This type of shot is only good for documenting the progress or how to build the layout. By taking the camera down to the track level you get a much more natural image:

Choose interesting perspectives:

If you have a backdrop image, use it.

Don't be afraid to make even longer exposures for night scenes... see http://layout.mixmox.com/1/day_night

Remember to switch loco lights on etc.
