Default Photo lightbox

In a departure from modelling I decided to build a small lightbox/photo stage for photographing my locos.
A simple open fronted box, lined with white card and a few strips of LEDs left over from my layout lighting provides a consistent and even light source for the photos.

I need to sort the depth of field out on oblique shots like this.

And the real loco at warley

Nice even results

For the depth of field issue have a look into focus stacking, its ideal for this sort of thing.

As the previous post indicates, to compensate for depth of field at small scales you use a procedure called 'focus stacking'. There are cameras for botanists and entomologists which do this automatically. Railway Modeller uses an expensive camera and proprietary software, but you can do it using a cheaper camera and freeware you have downloaded.

Thanks for the suggestions, but for this purpose I will be going for a more appropriate aperture setting. (I don’t believe in photediting on a PC preferring to do all my adjustment ‘in camera’).
The test shots were on auto and I ended up with f3.3 which ain’t going to cut it. F11 and a slower shutter speed should suffice.

You can also up the ISO setting for a higher shutter speed, or move the camera away from the subject a little and increase zoom to get a greater depth of field.
I Like the light box .

I like to agree that it gives very good results.

Very nicely put together Steve. Are there LED lights the other side of the metal bars on the front, or just the top outer edges and down the front edges? Gives a great result. R-

Yes Roger, it’s two strips of aluminium U channel containing two extra strips of lights providing head on illumination and a convenient carrying handle.
If I were building it from scratch I would have square sides rather than sloped and fit at least three rows of ‘channel lights’ as the current position leaves a bit of a shadow at the front when photographing OO gauge locos as I have to pull the camera back a bit.

I can see a mark two version coming along in the new year.

Steve have you thought about Flash Guns a long time back i had 3 firing off detectors, angled corners, tissue to spread the flash light, a prime lens around 30mm set at one stop under its maximum, if you have a half decent flash it would work using the DSLR built in flash to trigger a second unit,,,, I don't have time at the moment but a couple of months i will set something and see how it goes.....
