As seen on FB but referring to a group called The Darkroom Darkroom tip! If you have an iPhone you can invert your screen to look at your negatives. All you have to do is go to "settings" click "general" then "accessibility" >then go all the way to the bottom to "accessibility shortcut" and select "invert colors". Once you do that, if you triple click the home button your screen colors will invert. Triple click home button to go back to normal colors. It's a fun thing to do when looking at your b&w or color negatives! FYI, Andy
