3 Steps to Creating Retro Tones in Photoshop
Instagram filters and Pinterest boards have increased the popularity of post-processing with retro tones. This look is easy to create in Photoshop. The basic steps combine a cream-colored fill layer, dark blue layer set to exclusion and levels adjustment (blue channel only).
After opening up your image in Photoshop, select Layer > New Fill Layer > Solid Color. Select white (#ffffff) or a soft rosy pastel color (#f6ebeb works great). Choose a low opacity like 10% and set this layer to Screen for a light hazy effect.
Next, follow the same steps, but choose a dark blue (#0c0c93 and #05275a are my favorites). Setting this layer to Exclusion at a medium to high opacity like 70% creates a warm honey tone.
The last step is adding a cool vintage hue using a levels adjustment only altering the blue channel.
To create a moderate effect, highlight the first layer in the palette and also select the last one. On the top menu under Layers, click on Group Layers.
Adjust the opacity to taste.
