Infrared Photo Editor
Infrared Photo Editor provides fast and easy color channel manipulation tools for photos. It supports RGB and HSL mixing, and brightness and contrast manipulation for all and individual channels. It was primary designed to manipulate infrared photos captured with mobile phone cameras but Infrared Photo Editor also works well with normal photos.
Infrared photos are an interesting area in photography because they show the world from a different view. For example, foliage appears white in infrared spectrum.
Luckily, many mobile phone cameras can capture infrared pictures with a simple trick. You just need an unexposed, developed analog film strip which you can usually purchase in a photo store for around 10 Euros. You can also get a film strip from us.
If your local store does not offer the required film strips then you can also purchase two 10cm film strips ready to use for infrared pictures here for 4.99 Euros which covers the material and shipping costs (please send a Paypal payment to "firstname.lastname@example.org" with 4.99 EUR and your postal address. We will immediately ship the film strips).
You need the following material to get started:
- Unexposed and developed analog film strips (you can get it here)
- Sticky tape
- Mobile phone
- Camera application (recommended: CameraPro)
- Optional: Infrared Photo Editor to develop infrared pictures
- A green plant (e.g. tree, gras, etc.) and sufficient light (best: sun light but a light bulb is ok too)
First, cut the film strip into pieces so that each piece can cover the camera lense. Then place the film strips on top of the camera lens.
Place as many pieces on the camera lens until foliage of plants turns white:
Finally fix the film pieces to the mobile phone with sticky tape.
Now you are ready to take infrared pictures.
Almost every camera has a built in infrared filter, either as a separate plastic layer, or directly attached to the camera lense. This infrared filter filters out infrared light to improve image quality. Often it is wrongly stated that cheap cameras, such as those used in mobile phones, do not have an infrared filter.
The film-based filter trick presented above uses the fact that the infrared filters cannot filter out all infrared radiation. The main disadvantage is that the presented filter works only under very good light conditions such as outdoors with sun shine, or objects illuminated with a light bulb.
Below are some hints to get sharp and bright pictures:
- Turn off autofocus and use infinite or hyperfocal focus instead.
- Set ISO as high as possible or to "Auto"
- Set exposure mode to "Night" or "Auto"
- If possible, do not use brightness/contrast/exposure compensation controls. It is better to adjust these values later with the Infrared Photo Editor.
