What do people use to have the perfect picture on Instagram?

I mean like the picture is very clear and the lightning is so perfect because I'm sure they don't use iPhone

Lol. Some people do actually use just Instagram. Auto correct and LoFi. But yes there are many other apps. For example BeFunky is a good editing app. Also just the auto correct on the iPhone. You could also just focus the camera when you are taking photos. I hope this helps. Here is some of my work if you would like to check it out. My instagram is @cucucrazzi004 and or @jinxerz004 or my website

To create the perfect picture on instagram, a gallery wall, a magazine cover or anywhere, people use skill, talent and experience.
