How To Change Backgrounds in Snapseed | SNAPSEED TUTORIAL | Android | iOS

Today we are gonna manipulate this image and create a silhouette look using the free Snapseed app. 

First thing to note, I will be adding this sky
image as the background.

• So I need to match the colors and brightness of this sky image to the foreground here in the original.
• So using Curves, I am gonna just lower the top right point down and darken the overall image.
• Also adding some yellowish tint by dragging the blue curve towards right.
• I am gonna save this.
• Reverting to the original state.
• To separate the foreground from the background, first step is to convert the image to black and white.
• 
  
• Here in the color options, choosing the color which gives most contrast between the foreground
• and the background.
• Blue is the best option here as all the bluish colors in the image becomes white mainly the
• sky here and the remaining dark.
• Now I need to make the grayish colors to completely black and white.
• So again with Curves dragging the lower part to the right and downwards to move the darker
• parts more towards black.
• Similarly the upper part of the curve to make the brighter parts completely white.
• Need to play with this till you get the desired results especially around the edges between
• the foreground and the background.
• To turn those white spots in the foreground to black, using the Curves, turning the whole
• image to black by dragging the top point towards bottom.
• Now going to the masking screen.
• With the effect disabled and brush value set at 100,
• brushing on the white spots to turn them to black.
• Need to zoom in especially around the edges to be more precise.
• On the subjects too.
• Now I am gonna add the last saved image using Double Exposure and choose the Add option.
• After applying this, saving this as a separate copy and deleting the last Double Exposure effect.
• With the black foreground here, I am gonna use Curves to invert the image and make the
• foreground white and the background black.
• Will save this and remove this effect.
• Coming back to the state where the foreground is black, I am gonna add the sky image now
• using Double Exposure and choose Darken option.
• Scaling the image and placing it at a desired position.
• Applying it.
• Now I am gonna use Curves to alter the colors of the sky a bit.
• First adding some brightness and yellowish tint...
• ...and then more brightness and yellows.
• With masking, applying just around the subjects.
• As the subjects here are black, the effect doesn't affect the subjects.
• Now using Double Exposure, I am gonna add the earlier saved image of white foreground
• and black background.
• Choosing the Add option which makes the foreground completely white.
• Now adding one more image saved earlier of the foreground intact image but with white background.
• Choosing the Subtract option and applying it.
• Now you can see the almost finished image.
• I am gonna add one more edit especially on the foreground with a Selective filter.
• Just adding little more brightness and contrast.
• Removing this effect in the sky using masking.
• So here are the changes after each effect applied.
• And the final result.
