Edited Image 1-Change Brightness to +50-Change Contrast to +80-Change Hue to -15-Change Saturation to +10-Change Lightness to -5-Select sky using quickselection tool-Apply «Rough pastels» effect-Select wheat using quickSelection tool-Apply «Film Grain» effect
Edited Image 2-Use «Spot Healing Brush Tool» to erase airplane trail, abnormalityIn wheat and over-bright center ofMountain-Use «Smart Brush Tool», select skyAnd make brighter.-Use «Smart Brush Tool» select wheatAnd increase contrast-Use «Smart Brush Tool» select mountainAnd use «Greenery» function
Edited Image 3-Use cookie cutter and cut out heart-shaped centre of image-Open enhance and adjust color curve to:
-Min Highlights-Max Midtone Brightness -Max Midtone Contrast-Min Shadows
- Insert generic lake image on background
- Drag heart on to Image
