You need to use our template, to use pre-existing art please see this tutorial.
Make sure to have a good source of natural light, outdoor lighting is best! Sunny or cloudy it’s the same. No flash is better.
Pay attention not to photograph your phone shadow on the template and try also not to wrinkle the paper.
Make sure the picture is nicely in focus and sharp! The sharper the picture, the better the dress!
All recent smartphones have really good resolution, anything above 5MP will work great.
Get as close as you can to the template without cropping out any part of it out of the picture
