HDR Modes
Machinery has three different techniques for merging together HDR images.
|
Contrast Detection
The program chooses the best fragments from selected frames. Transitions between frames are very gradual, which can show up as a darker or lighter glow in areas of high contrast.
The advantage of the mask mode is that is keeps the contrast of the original frames.
|
|
|
Edge Detection
The program chooses the best fragments from selected frames. The transitions between frames are more abrupt than in the "Contrast Detection" mode because the algorithm detects the edges of objects in the frame. This mode allows users to substantially eliminate the glow visible in the "Masks" mode.
The advantage of this mode is that is keeps the contrast of the original frames.

|
|
Natural HDR
The program creates one image with a dynamic range that incorporates all loaded frames. This mode fully eliminates the glow effect, but can generate images with low contrast.
|

|
Natural HDR + Microcontrast
If the image created with the "Natural HDR" mode does not have enough contrast, you can fix the problem with the help of the Contrast effect, available in the HDR pane.
It is recommended to create HDR images using the Natural HDR mode and then increasing the microcontrast level.

|
Natural HDR + Details
If the image created with the "Natural HDR" mode does not have enough contrast, you can fix the problem with the help of the Details effect, available in the HDR pane.
It is recommended to create HDR images using the Natural HDR mode and then increasing the details level.

Auto-alignment of images series shifts
Sharp shots consisting of several frames, even if you take series of photos "from hand". Use the option "Image ->Align Source images" to enable auto-alignment. Access program configuration to turn on automatic alignment for each new project.
Deghosting
If the successive images have shifting objects, e.g. a car driving past of moving people, the stitched image will contain so-called "ghosts", visible as blurred or semi-transparent fragments. To remove this effect, go to "Image -> Deghosting" in the HDR Panel. Access program configuration to turn on automatic deghosting for each new project.
