One of my favorites is picnic that allows you to evening real-time edit the lighting in your entire photo. The sky changes almost everything else and it is the most convincing effect out of all the apps I’ve tried that offer similar features. It’s just fun when I’ve taken a photo of something, I just find myself thinking if this could look even better if I played with the lighting effects. For example, See my shots in Hawaii a couple weeks ago and it looks pretty great but I definitely think it’s an improvement when I apply the sunset preset. But we can do better still – snow storm and truth be told most people I should the image to didn’t even question but it was fake the responses were mostly oh wow I didn’t realize it snowed in Hawaii
