It always surprises me how much my followers appreciate how candid my photos are - they may not have a particularly unique subject, but it's more about the light you shed on the subject than the subject itself.
Using the correct apps can completely change how your photos look. It's really exciting because once you've already taken a good photo, it can become 10 times better if you use the right combination of apps. My favorites are VSCO Cam, Afterlight, Facetune and SKRWT.
