Manual for Thermal Camera (iOS) 
You can support the developer by giving him a small donation.
Donate!Photo Button 
This button takes a photo. The app can save it in three types:
- Thermal image
- Real color image
- Flir Tools compatible thermal image
You can switch each image format on or off in the options with the setting: Images to save
Only the third image type can be opened and edited in Flir Tools. And if this feature is not used, it is recommended to deactivate the third image type due to its larger size and the missing extra features (like min/ max temperature, deactivated MSX, ...).
Cross Hair 
You can use the Cross Hair to find the temperature of an element on the thermal image. The cursor can simply be drag'n dropped around the screen and the temperature behind it is displayed on the bottom, above the image taking button (See title image). You can reset the cursor by double tapping on it.
The cursor can also be hidden by tapping the cross hair icon on the right of the temperature. If done so the cursor will also be not saved when taking a photo.
Palette
The palette defines how the thermal image is colorized. There are currently twelve different palettes available:
| Palette | Palette used for Flir Tools compatible image |
Cold - Color - Hot |
|---|---|---|
| Iron | Iron |  |
| Iron Gray | Iron |  |
| Black/ White | Gray |  |
| Inverted Gray | Gray |  |
| Arctic | Arctic |  |
| Lava | Lava |  |
| Rainbow | Rainbow |  |
| Double Rainbow | Rainbow |  |
| Rain | Rain (Contrast) |  |
| Color Wheel 12 Colors | Color Wheel 6 Colors (Wheel) |  |
| Color Wheel 6 Colors | Color Wheel 6 Colors (Wheel) |  |
| Color Wheel Redhot | Color Wheel 6 Colors (Wheel) |  |
Most palettes don't have a representation in the Flir Framework and are not saved with the Flir Tools compatible image. Here the app chooses a palette that's very similar to the selected one. See the second column in the above table.
You can also change the upper and lower bounds of the palette. Either by setting them manually or by locking the palette. It should be mentioned that the Flir One has huge temperature jumps (<2 K) before and after tuning.
You can also change the gamma value of the palette by sliding up and down on the screen. For more information see the Gestures Section.
Min / Max Temp. 
These two numbers always represent the min / max temperature of the current palette. They can currently trigger only one action:
- Long press: open dialog to change lower and upper bounds of palette
The upper and lower temperature bounds are only saved with the Thermal Image format.
Gallery 
This button opens the gallery, which only shows the last image taken in this session. It was implemented so that one can quickly verify if the image is good without closing the current session.
Switch to Camera Roll
This will switch to the camera roll, where all last images are located.
The app instance will close if you go out of the app. With it all small settings like palette locked or min/ max temperature will be lost.
Image Switcher
By pressing the different items, you can switch between the different image formats. If one image format was deactivated in the settings, the corresponding item button will be grayed out like the Flir Tools compatible image format button above.
Back Button
This will return to main screen of the app.
Toolbar Opener 
This button opens the Toolbar.
Toolbar
This menu contains shortcuts to some relevant settings that are needed to use the app. It can be opened by tapping the toolbar opener.
This menu contains from left to right following buttons:
Palette Chooser 
This buttons opens the dialog to choose between the different palettes.
Tuning Button 
Tapping this button triggers the tuning of the camera.
Palette Locker 
A simple tap will lock/ unlock the palette. If the palette is locked, the max and min temperature will not change anymore.
MSX Toggle 
This button switches between the non combined (no MSX) and combined (with MSX) mode of the real color and thermal image. By default, the app starts in the non combined mode. This will also be saved with standard thermal image.
Options Button 
This button opens the standard settings menu. See the Options section for more information.
Options
Unit
Here you can select your preferred unit. Possible options are:
- Celsius (ºC)
- Kelvin (K)
- Fahrenheit (ºF)
- Rankine (ºRa)
Emissivity
This value is important to calculate the right temperature for the viewed object. For more information about it, take a look at: Wikipedia.
One can only choose from following emissivity values:
- ε=0.95 Matte (default)
- ε=0.80 Semi matte
- ε=0.60 Semi glossy
- ε=0.30 Glossy
Hide Real Color Image
You can hide the real color image in the bottom right corner of the screen with this button.
The real color image format will still be saved, even when this option is activated.
MSX Zoom
The configuration of the cameras inside the Flir ONE can change between the models. If the images don't overlap one should choose a different zoom setting for it, but 100% is default value.
Images to save
With this option, you can toggle each image format for saving on or off. For a list of available formats, look in the Image taking section.
