I used all of the apps below (except HDR Fusion)
STEP 1: I use SnapSeed
1. Tune Image
• Brightness +15
• Ambiance + 5
• Contrast + 20
• Saturation+ 22
• White Balance +5
• Dark 1 then tune the Saturation to +100
• Filter should be around +90
STEP 2: I use Weather FX to add the lightening and the flares for the stars. Add as many as you wish. I try not to overdo it though.
STEP 3: Using LensLight, I like to add some extra flare to the sun . You can add different colors and even add more stars and lightning.
STEP 4: I open the photo in Xnview FX
• Select Actions
• Mixer, then chose the color
STEP 5: I open in Pix
STEP 6: go back into Snapseed
Lastly open in Squaready and make sure it fits nicely and I then chose to Watermark my photos using IWatermark.
