Excellent for sharp delineation of hot/cold areas.

* Greyscale/White Hot: Best for documentation where visual realism is preferred.

2.4 Focusing and Image Capture

Sharp images are critical for accurate analysis. Thermal images require focus, just like visible light cameras, though the process is different.

Focusing Methods

• Automatic Focus (AF): Pressing the focus button once usually snaps the image into focus based on the center reading.
• Manual Focus (MF): If AF fails (common with very distant or very close objects), use the joystick or dedicated focus ring/buttons to manually adjust until the image appears sharpest.

Capturing and Saving Images

1. Framing: Frame the area of interest, ensuring the target fills a sufficient portion of the screen.
2. Focus & Adjust: Ensure focus is sharp and contrast/level adjustments (span) are optimized.
3. Capture: Press the shutter button completely. The camera will momentarily freeze the image and prompt you to save it.
4. Saving: Select 'Save' on the screen or press the shutter button again (depending on the model configuration). Always add a brief note or inspection ID if the camera supports annotation features.

2.5 Reviewing and Managing Files

To review previously captured images, exit the live view screen and enter the image gallery (usually indicated by a folder icon).

• Navigation: Use the directional controls to scroll through images.
• Image Analysis: When reviewing a saved image, the camera often allows you to move the spot meter, change the color palette, or adjust emissivity after capture (metadata adjustments), which is a powerful diagnostic tool.
