Making my final images

I created these multiple exposures in Photoshop:

Each image has 3 different image, a scene, a portrait and a bedroom scene.
Each image started with a bedroom scene image. I then added a scene image and lowered the opactity and changed the blending mode (usually to multiply or darken) until it looked blended but visible.

I then added the portrait on top of these using the mask tool and slowly revealing the portrait with a detailed brush. I used brush 66 to add the portraits in to my multiple exposures. I added the portraits in at a low opacity and layered the opactity by using the brush more over certain areas like the eyes as I wanted these to show more as a focus point. I blended the portrait in to the rest of the image by lowering the opacity of the brush whilst adding in the edges of the person in the portrait. I made sure the portrait was enlarged and placed in the image to keep a good composition rather than placing it randomly within the image.

I then lowered the saturation of all of the bedroom scenes to -100 to remove all colour. I lowered the saturation levels of the portrait and scene to around -80 so that they still showed slight colour but not too much as I thought the colour of the saturated images was too bright and made the images look too busy as the colour was quite distracting.

When I took the colour away from the layers I then added a gradient map over the layers and chose colours for the gradient map that would have been in the images before I took away the saturation as I thought it would be fitting. I used the soft light blending mode for all of my gradient maps as I thought this worked nicely as it wasn't too contrasting. I lowered the gradient opacity to between 50-80% to create a nice soft colour tone which fitted with the dream-like feel I was trying to create.
