Camera – Smartphone or DSLR?
Many smartphones take pictures at our required 3000x3000 pixel resolution. You can use an iPhone (6s, 7, 7 plus); Samsung Galaxy S6 and S7; and the flagship models from other manufacturers. With that said, a DSLR camera will always give you the highest quality photos.
We would also recommend hiring a photographer for your artwork and promotional pictures. Ask yourself: doesn't all the hard work getting the song done deserve the best possible presentation?
