You can effectively change the background color in Lightroom Mobile by using selective masking and adjustments. Here's how:
-
Select the Subject: Use the "Select Subject" masking tool to automatically create a mask around the main subject of your photo.
-
Invert the Mask: Invert the subject mask. This will select everything except your subject, effectively selecting the background.
-
Adjust the Background: Now that the background is selected, you can modify its color:
- For a White Background: Increase the "Exposure," "Highlights," and "Whites" sliders towards their maximum values.
- For Other Colors: Use the "Color" or "Hue" adjustments within the mask settings to shift the background's color to your desired hue. "Saturation" can be adjusted to make colors more or less vibrant.
-
Fine-Tune the Mask:
- Addressing Imperfections: If parts of your subject are inadvertently affected or elements of the original background remain, use the "Add" and "Subtract" tools within the mask to refine the selection.
- Duplicate the Mask (if needed): If the background has varying tones or details that require separate adjustments, duplicate the mask and adjust the settings accordingly for each area.
-
Tweak Settings: Depending on the image, further adjustments to "Contrast", "Shadows" and "Blacks" within the mask might be necessary to achieve a natural-looking result.
In summary, changing the background color in Lightroom Mobile involves using masking tools to isolate the background and then applying adjustments to achieve the desired color.
