Infrared Photography Manual For Fujifilm Finepix S2900 Series Cameras

There are two ways to take infrared pictures with the camera. (1) Modify the camera and make it Wide Spectrum (also known as Full Spectrum) or place in the camera a filter that will make the camera 720 nm, or other wavelength permanently.

(2) Use the camera without any modification and place filters in the front of the lens. This usually results in long exposures of 10s or more.

Preparing Full Spectrum (Wide Spectrum) Camera to Take Deep Black and White 850 nm Pictures

Power on the camera.

Place an 850nm infrared filter on the lens.

Take a grey card. We will use it to set a Custom White Balance in the camera.

Set the dial on top of the camera to the letter P (Program).

Press Menu and the down arrow a few times until you see the White Balance menu option. Press the right arrow or OK.

Use UP and Down arrows to select Custom.

Fill the white rectangle frame in the view screen with the grey card and take a picture by pressing the Shutter button. Press OK to confirm if needed.

Now you will be able to take Infrared Deep Black and White images like ones shown below.

How to Take 590 nm, 690nm, 720 nm Infrared Pictures

The procedures are the same as above:

• Place a filter in the front of the lens.
• Set custom balance to a grey card. (Asphalt or something similarly grey works as well). Alternatively, you can set white balance to the grass. This will make grass appear white.
• Take pictures. For best results with infrared images, take pictures on a sunny day.

In addition we will do a channel swap. Please install the Gimp software.

Open an image for editing: File -> Open.
Adjust color levels by going to Colors-> Levels. If needed, slide the arrow from right to left to make the image brighter.

Swap channels. Go to Colors>Components>Channel Mixer. On the red output channel, adjust red to 0% and blue to 100%.

Next, select the blue output channel. Set red to 100% and blue to 0%.

Further actions very depending on your taste. For example, you can make the sky blue by adjusting the hue or increasing blue in the channel mixer, etc.
