1. How can I save the result picture?
A: Please register your product. After registration, the "Register" button will change to "Save To File", and you can save the picture as you want.

2. Why is it some slow to save a file while I make the check of "Reduce Noise"?
A: The option of "Reduce Noise" will enable an intelligent algorithm to reduce the noise in the picture while saving. The noise can be introduced from high ISO value when you shot a night scene. The algorithm uses an expensive convolution processing operation. Please use this option very carefully.

3. What's the meaning of "Radius" and "Sigma"
"Radius" and "Sigma" are two parameters for Convolution processing operation. Many effects like "Sharpen", "Blue", "Oil Paint"... take "Convolution" as a basic processing operation. If you are not familiar with "Convolution", you can just think "Radius" is a range that the operation will take effect and "Sigma" is the degree of how much the operation involved. The safe way to get the meaning of these two parameters is to modify them and see the result!

4. Why the adjustment page is reset after "Save To File"?
"Save To File" means the result has been accepted, and the result should be set to the base point for next adjustment.

5. What's the meaning of "Amount", "Threshold" in "Unmask Sharpen" page?
In summary, "Unmask sharpen" is an operation like this equation: "result picture"= "original picture"+ Amount x ("original picture"- "blurred picture"). If the pixel's brightness is greater than "Threshold", the algorithm will take effect, or the original pixel value will be copied.

6. Why are there no changes when I select/unselect "Auto Enhancement" from "Configuration"?
"Auto Enhancement" takes effect while a picture is loaded. You can double click the source file to let the effect applied to the current picture.

7. How to print out the picture from the software?
You can not do printing in 1.0 version. But this feature will be a candidate requirement for next version.
