Does anyone know Apple's camera software that operates like a SLR?

I recommend you to download the POCO camera APP, which has a variety of lenses built in to make your mobile phone camera more powerful! Double exposure lens, fisheye lens, four-grid lens, jigsaw lens and shift lens let you experience the fun of taking pictures! The iPhone version also supports the professional focusing and metering separation functions of SLR cameras! Built-in "GIF short video" lens! Let photographers and video creative people not only express themselves with pictures, but also realize "creative super-dynamic short video photography"!
