For more information on other steps in the Imago image capture workflow refer to articles listed at the end.

The starting point should be the Profile to be used by Imago Capture X.

1. A Profile incorporates such aspects as:

The Workspace and Dataset to which the images will ultimately be uploaded to;
Imagery Type(s) with associated Image Type(s) defined for the Dataset;
Capture operation mode, sensor mode, and several camera setting such as quality and sensor to use;
Whether to use Box Numbering, Image cropping, and other aspects;
Assigned users which will allow them to use the Profile when capturing images in Imago Capture X.

2. After a Profile has been created a post-capture Action Definition(s) need to be defined. Imago Capture X will process according to these actions.

3. This Action Definition is then assigned to the relevant Workspace/Dataset.

This article describes these steps.

1. Create a Capture X Profile

A Workspace and Dataset must exist which incorporates Imagery Type(s) and Image Type(s) to be used.
A User with Administrator or Subscription Owner privileges can create Imago Capture X Profiles only.

Let's create a Profile for the Drilling Core Dataset in the Firefly Workspace:

1. In Settings, select Profiles:

Existing Profiles are listed which may be edited by clicking a Profile.

2. To create a new Profile, enter a Profile name (Firefly Chips in this example) and select imago-capture-x for the Profile Type:

3. The Profile Definition page is displayed. As this is quite a long page, let's work through by Section:

Ultimately, the captured images need to be located properly on the Imago Portal. 1 - 3 ensure this.

Workspace & Datasets	1. Select Workspace (e.g. Firefly Resource Development).
	2. Select Dataset (e.g. Drilling Chips).
	3. Select Imagery Type (e.g. Wet).
Capture Operation	4. Enter a Camera Operation Name (e.g. Wet). For each camera operation, a tab is created (5) where operation parameters are entered.

Capture		Select Sensor Capture Mode	Option
	4		wait	Select this option when the camera is not compatible with Imago Capture X. Photographs captured can be saved to the Watcher Directory and from there they can be imported directly into Imago Capture X for upload to the Imago Portal. See Supported Cameras to see if your camera is compatible or when planning to buy a camera. For more information on setting up a Watcher Directory, see Import Images and Watcher Directory Options.
			trigger	Where a camera is compatible, the computer (Imago Capture X) controls the camera operation.
			use station settings	Operate the camera manually. This is rarely used and not recommended.
	5	Enter a Capture operation name	Enter a meaningful name e.g. Wet Core or Dry Chips. There can be multiple Capture Operations in a single Profile. As soon as the first name is entered, Capture Operation 1 is displayed. This will increase for each subsequent Capture Operation e.g. Capture Operation 2, Capture Operation 3, etc.

Workspace & Datasets	1. Select Workspace (e.g. Firefly Resource Development).
	2. Select Dataset (e.g. Drilling Chips).
	3. Select Imagery Type (e.g. Wet).
Capture Operation	4. Enter a Camera Operation Name (e.g. Wet). For each camera operation, a tab is created (5) where operation parameters are entered.

After populating the Profile for the above selections/options:

Capture Operation 1	6	Review before accepting	When selected, each time a photograph is captured, Imago Capture X will ask whether you wish to accept or reject. However, this is somewhat of a redundant option because, if not selected, the photograph is still shown in Imago Capture X and if not satisfactory it is a simple case of retaking the photograph.
	7	Use read all mode for directory watchers	This option applies when the sensor capture mode is set to 'wait' (see earlier). Imago Capture X read all formats that are in the Watcher Directory. If it is an image format, Imago Capture X will likely accept it.
	Capture These Images Simultaneously	8a	Image Type	Select one of the Image Types from the list. In this example, there is only one (Wet). If there are more e.g. Dry, this could be added too. Only relevant where the Watcher Directory Options are configured in Imago Capture X. See Import Images and Watcher Directory Options for more information.
		8b	Image Type	After the Image Type is selected, a list of options are displayed (9 - 12 below) for the selected Image Type.
		9	Target Sensor	Think of a Target Sensor as a camera. They are one and the same. There are two choices: RBG1: Camera 1 RGB2: Camera 2 Imago Capture X can work with two cameras, hence the choice. If there is one camera only, select RGB1.
		10	File Format	Three capture formats are available: JPEG PNG TIFF The capture will be uploaded in the selected format.
		11	Quality	This relates to JPEG only. The default is 90. A lower value may impact the resolution of the image. A higher value is unlikely to be noticeable in terms of quality, but it potentially will impact upload and processing time due to larger file sizes.
		12	Rotation	Select a rotation if the captured photograph(s) are incorrectly orientated. Imago Capture X will use this when capturing all images.
	Before Capture	13	Action Type	This is only relevant for a Chipshot camera. A movement will be triggered ,such as light or UV light, before the photograph is captured.
	After Capture	14	Action Type	If Chipshot is selected (above), selecting poweroutlet provides the means to turn the power outlet on or off depending if UV light is being used.

Repeat the steps 5-14 for Dry (or any other type of core)

With the Capture Operations set, the next step is to select the remaining options for the Profile:

Increment Options	15	Auto increment interval	If the number of boxes/trays is known e.g. 10, selecting this option will increment up to this number.
	16	Increment Length	This is the length in units (e.g. 10 metres). Imago Capture X will use this value to automatically increment to the next depth after a capture has been made, without the need to enter a value:
	17	Increment direction	As the name implies, this is the tells Imago Capture X whether to increment up/down to/from the Auto Increment Interval. In some cases there may be a need to count down from 10 rather than up to 10.
Upload Options	18	Only upload when all images are captured for an interval	There may be circumstances where different Image Types are being captured. When selected, photographs will not be uploaded to the Imago Portal until both are captured for the interval. It is recommended not to select this option. It may be removed in a future version.
Upload Options	19	Only upload when collection exists in the cloud	Select when the Collection exists in Imago Portal. However, if the Collection does not exist, it will not be possible to upload captured photographs. It is recommended that this option not be selected. This will allow Imago Capture X* to create the Collection on the Imago Portal as it uploads photographs.*
Quality Control	20	Minimum Interval Length	Enter a minimum value for the anticipated start depth. Imago Capture X will display a warning message if a value is less than this.
Quality Control	21	Maximum Interval Length	Enter a maximum value for the anticipated start depth. Imago Capture X will display a warning message if a value exceeds this.
Box Options	22	Allow Box Number Recording	Select to record the Box Number (see screenshot 16 above).
Box Options	23	Allow Multiple Box Numbers	Select if the capture will be across multiple box numbers. Imago Capture provides an additional entry point for the end box number:
Image Options	24	Allow image cropping	Select to allow cropping on the captured photograph. For example, core tray and runs. Imago Capture X will display options for Image cropping:
	25	Allow core frame to be defined	Select to allow define the core tray. Red outline in the above image. Green represents runs in the tray.
	26	Only upload when core frame is defined	This is a safety feature to force the core frame to be defined.
Advanced	27	Export Profile	Export the profile in JSON format
	28	User Permissions	Click to move to Profile Permission tab. This assigns users to the Profile. See Manage User Roles, Permissions for more information.
	29	Assign Security Groups	Click to move to Profile Security Groups tab. This assigns one or more Security Groups to the profile. See Manage User Roles, Permissions for more information.
	30	Archive	Click to permanently delete the Profile.

2. Create an Action Definition

With the Profile created, the next steps is to create an Action Definition for which defines Image Transformation. Essentially the Image Transformation is performed by Imago Capture X allows for such actions as defining:

Boundaries for core trays and individual runs;
Image quality and more.

1. From the Left Panel, click Definitions and enter a name for the Action Definition and press Enter:

2. Enter a name (1) for the action type, this is then listed under Actions (2) and configure the Action Type by clicking the small pencil (3):

3. Select an Action Tool from the dropdown list:

4. We will select Image Transformation from the dropdown list. This will perform cropping to a boundary in Imago Capture X. The Action Type page is displayed:

Action_Definition_-_Populate_Action_Type_-_Image_Transformation.png

With the page populated, let's look at the options:

1	Destination Image Type	Enter an Image Type name (e.g. Wet, Dry). This reflects the source that is being captured.
2	Cropping By Boundary	Selecting this option will indicate to Imago Capture X that the user will digitize a cropping boundary e.g. a core tray or chip box. SELECTED.
3	Cropping By Margins	These are enabled when 2 is selected. Select to allow Imago Capture X to determine the boundary based on the percentages entered below.
4	Left/Right/Top/Margin (%)	Enter a value to indicate to Imago Capture X that the boundary is to be x% in from the photograph border.
5	Title Box Position	Select a Position for the Title Box (Top, Bottom).
6	Title Box Text Size	Select a Title Box Size (mm).
7	JPG Quality	Image quality. Select from 50, 80, 90, 100. 90 is a good choice, reducing image size, without compromising quality.
8	Sharpen Image	Sharpening is a technique for increasing the apparent sharpness of an image. It subtracts a blurred (unsharp) copy from the original image to detect any edges. A mask is made with this edge detail. Contrast is then increased at the edges and the effect is applied to the original image. Experiment to see if this improves/detracts from the original image.
9	Adjust Colour to Full Dynamic Range	Images may be captured in a limited dynamic range. e.g. 16-235. Selecting this option will adjust to the full dynamic RGB range is 0-255. Experiment to see if this improves/detracts from the original image.

Repeat the steps in this section for Dry (or any other type of core).

3. Configure Imagery Type to Allow Image to be Displayed and Scaled downhole

1. Select Definitions>Imagery Types:

2. Select the relevant Imagery Type. In this example, core trays are for an Imagery Type that has already been created for Firefly Resource Development:

3. Click to the Imagery Type to select:

1	Enter a name for the new Image Type.
2	Imago adds to the list of Image Types.
3	This Image Type will store the individual downhole (linearized) cropped core tray runs. Select Derived.
4	For the Wet Image Type, we want Imago Capture X to take the original image and crop according to the action definition defined earlier and place into the Image Type defined in step 3 (Wet). Select Wet Cropped.
5	Finally we want to linearize the Wet core. Select Linear/Wet
