LCA+'s MX function gave Lomographers tons of unexciting and surprising images. Having said that, follow this tipster and looking at it from another angle can give your MX photos more power!
Use LC-A+ Splitzer shoot 50/50 MX photos (I recommend 50/50 as it is easier to control)
1) Shoot the first image
2) Rotate the LC-A+ Splitzer to the other half, press the MX switch
3) Turn your LC-A+ Upside Down
4) Shoot the first image again
In this way, you can get “symmetrical” MX images, which becomes your “Art Piece”!
