It has finally arrived. Mask editing tool thanks to which I can always improve, even if the image is acceptable, I always see if I can make it better.
Manual parameterization is advisable especially when you want a perfect picture for the home page, preparing the product image for website banner. Mode’s background removal algorithm (BGR) is now enhanced with a tool that clearly allows the user to control the quality of the edge and …expenditure at the same time. After all, it is known that the salary of graphic designers is calculated per hour of work, and the modification of the mask saves this valuable time.
In this short post I decided to focus on discussing 3 parameters available to users:
# DENSITY. Actually… this is a threshold value known to all photography enthusiasts. Thanks to this feature we can decide what should be visible in the picture and what should not. If the automatic parameterization fails and a fragment of the object is lost – we can easily recover details by pulling the fill slider. You have to do it sensitively and observe chages within the whole image. In extreme cases, excessive filling reveals an unwanted fragments of platform or dust fragments. It can also work the other way round: when an unwanted white border appears on the edges of the product, we can easily get rid of it by reducing the fill parameter.
# SMOOTHING – that’s cosmetic. Thanks to smoothing parameter the edge becomes softer and more pleasing for the eye. I don’t advise to exaggerate, because excessive blurring can spoil our perception of whole photo
FILLING AND SMOOTHING should be used parallel. Only this mix gives me the expected results.
Comparison of results: before and after mask modification.
It is worth noting that not all algorithms used in BGR activate the alpha channel. If the function is greyed out, just switch to the one that will light up the slider:
Transparent, Glasses, Bottles..
Below is an example of a perfect product which came out straight away from the system. MODE BGR is best parameterized to underlay a white background. This is the color most often used by professionals. Therefore white was the priority of MODE.
