Apply a light leak effect for that retro appeal
Firstly, set your Foreground colour to orange (ffa53b). Add a new layer on top of the Background and change its blend mode to Pin Light.
Select the Gradient tool (G) and then head to the Options bar. Choose the Foreground to Transparent option and set the gradient type to Reflected.
With the Gradient tool, draw a horizontal line across your image. This applies a band of orange light from top to bottom with the Pin Light blend mode.
Press V to quickly select the Move tool and then hit 6 on your keyboard to lower the layer’s Opacity to 60%. The light leak should be subtle but clearly visible. Try other blend modes such as Linear Light or Vivid Light for different effects.
