Live Preview User Workflow
|
1
|
Launch from Capture One
|
Launch Live Preview from Capture One. Live Preview is paused in composition mode as default. The composition window can be moved outside the Capture One application.
|
|
2
|
Open shutter
|
Open shutter and keep it open in B or T mode depending on choice of camera system.
|
|
3
|
Press play
|
Start composition mode by pressing the play button.
|
|
4
|
Adjust the exposure
|
Notice the reading on the exposure meter. Adjust the aperture until the exposure meter is in the "green" area.
If the Live Preview image seems too dark or too bright, adjust the ISO gain and/or the shutter speed. Lower ISO gain means less noise in the image. Higher shutter speed improves image quality at the expense of slower frame rate.
|
|
5
|
Set pilot lights
|
The best image quality is achieved with pilot lights set relatively low. High lights and high key areas may generate image artifacts in the Live Preview image. This will not affect the final image. Many fluorescent light sources typically have a non-steady behavior.
If the white balance is not correct, a new white balance can be set using the picker tool, and clicking on a gray area in the composition preview. Typically a gray chart is temporarily placed in the setup for this purpose.
|
|

|
Set image scene
|
When the exposure is adjusted, the set can be composed. To ease composition it is possible to turn on a square grid. The amount of grid lines and their color is adjustable through the use of the preference settings.
To further improve the workflow, it is possible to load an overlay image and compose with this as a guide line. Overlay opacity is configurable in the preferences panel.
|
|

|
Launch focus window
|
With the composition and pilot lighting in place, the focus window is launched by pressing the magnifier symbol, placing the magnifier symbol in the area of focus interest, and then left click.

|
Handling the focus window
|
In the composition window the focus area is indicated with a box. The focus window is launched and will be updated 1.5 to 3 times every second, depending on the size of the window. The window can be moved outside the Capture One application and ideally be placed on another monitor adjacent to the set. The focus window can be scaled and zoomed into for easier viewing from long distance if needed.
